A Water Workforce Needs Assessment: Human capital for tomorrow’s challenges

Carrie Sanneman1, Paul Manson2

1Willamette Partnership, United States of America; 2Portland State University, Center for Public Service, United States of America; ,

In the next 50 years, utilities will face unprecedented challenges. Across the Northwest, the sector needs to adapt to new regulatory requirements, a changing climate, and an aging workforce. For urban areas, those issues are compounded by the need to keep pace with population growth. In rural areas, the challenge is more often about accessing the funding or financing to make costly upgrades. Northwest utilities need a diverse and prepared workforce to meet those challenges. Willamette Partnership and Portland State University’s Center for Public Service, in collaboration with the Center for Sustainable Infrastructure, are partnering to learn how workforce development can best support Oregon and Washington utilities to design, build, and maintain the infrastructure of tomorrow. Throughout 2018, the project team has investigated the critical barriers that water infrastructure providers face in developing and retaining a reliably qualified and talented workforce. The team used surveys, interviews, and literature review to identify workforce-related barriers to high performance (e.g., availability of training programs, recruitment, retention, etc.) and propose solutions to improve the region’s water infrastructure talent pipeline, including tailored recommendations for large, small, rural, and urban settings. But the work doesn’t stop there. After the results are available, anticipated September 2018, the team will begin extensive outreach to share the findings and draft recommendations, building a solution set that utilities, technical training and apprenticeship programs, engineering and management programs of the region’s universities, and other workforce development partners agree can best develop our precious human capital.

And Now for the Hard Part: Evaluating and Measuring the Performance of Your Asset Management Program

Elizabeth Lowell

HDR, United States of America;

The need for an asset management program is greater than ever: infrastructure is aging, regulations are requiring higher and higher performance standards, and financing infrastructure maintenance and investment requires greater and greater supporting documentation.

And the truth is, asset management programs ARE documented at many utilities, with many more working through unofficial or ad hoc methods. So, is that it? Are we done? The answer of course, is no, and that’s because of the inevitable next question: is what we’re doing working?

Whether a utility or agency has been practicing asset management for years, or is just implementing its program, it naturally wants to know if all its efforts are paying off and delivering the desired results. In addition, savvy stakeholders, customers, and external management are starting to pay attention to that too. But measuring that kind of success can be a challenge. What does successful asset management look like? How do we measure that? And how can we use that to evolve into the future?

This presentation will tackle that topic by presenting a variety of ways to measure the impact of an asset management program, such as leveraging service levels, performing self-assessments using a standard framework, and engaging staff. It will also include defining what “success” looks like from different vantage points, including senior management, governing bodies such as boards and elected officials, the general public, and the employees of a utility or agency itself.

Attendees can expect to pick up tips on leveraging available industry resources, explore potential metrics or performance indicators that can be applied programmatically, identify opportunities and ways to engage with their stakeholders, and most importantly, learn from each other!

How to Make the Most Effective Use of Emerging Technologies to Meet Service Level Demands

Scott Bash

Jacobs, United States of America;

What if we redesigned the work using smart machines and the Internet of Things? Assets can self-monitor, collect data and communicate with other assets, and send event notifications to the owner. For years organizations have been talking about automating the business, but technology today is allowing us to digitalize the business processes and dramatically improve the ability to share knowledge. Instead of dehumanizing work, the technology helps people get back to what doing what they are good at. The opportunity is to use machines to augment people’s work and help them reach their potential without the constraints of paperwork and bureaucracy.

Utilities across the USA are learning how to use digital information along with business analytics and business intelligence (BI) tools to meet the growing demands of a “do more with less”, and in some cases a “do less with less”, society. Under these new data rich conditions, utility managers in Spokane, Portland, Seattle, Boise and across the Region are trying to figure out how to deal with all the available technologies and make the most effective use of available data.

Digital business transformation helps the organization improve process workflow by streamlining the data flow. Environmental regulations become stricter; society expects faster results, and the customers want it all to cost less. Technology can make internal business processes more effective and overall service delivery more cost efficient. The advent of the Internet of Things, mobile computing, machine learning and almost everything moving to the cloud makes us data rich but we need to turn that data into knowledge and share it enterprise wide. How an organization can determine the best course of action and leverage existing technology needs to align with business goals and available budget. This paper addresses the framework for information technology planning and knowledge management in a digital world.

Strategic Communications Can Build Awareness, Mobilize Support, Engage Critical Decision Makers, And Help Utilities Maintain Positive Perception While Securing Funding For Infrastructure Renewal

Kim Pallari, Teresa Platin

HDR, United States of America;

Utility infrastructure is critical to functioning communities; yet the public have little understanding until issue arises or rates increase. To build a positive reputation while securing funds to renew or replace aging assets, utilities must take a programmatic approach to communication. The right plan can alter perception and position districts for successful, supported and smart growth. This presentation demonstrates how to employ strategic communications to strengthen public trust.

San Antonio Water System (SAWS) operates large, complex systems that provide vital services, however information was lost in translation between high quality services and a customer’s bill on the kitchen table. To close that gap, SAWS began engaging personally and dynamically with customers. Using data-driven technology emphasizing visual design, SAWS’ real-time capital project map website showed how SAWS’ investments benefit the community and environment. These efforts paved the way for SAWS’ investments in capital improvement projects to comply with mandated sanitary sewer overflow (SSO) reductions.

In 2005 the City of Sacramento began installing meters to 105,000 connections and updating aging pipes to comply with State Mandate. The City secured several funding sources to accelerate the Water Infrastructure Improvement Program while minimizing customer financial burdens. This example will explore controversy the City faced and how they conquered it through rebranded themselves, their program and communication tactics to educate, repair damage and create good will. New messaging and brand identity created the framework for implementation of traditional and innovative online tactics to reach the diverse audiences. As the City continues, creative leave behinds guide customers on topics like reading your bill and water conversation.

Padre Dam Utility Water District provides quality drinking water, recycled water and wastewater management. Their 2015 Comprehensive Facilities Master Plan (CFMP) provides long range planning and reflects issues, trends, regulations and analysis to provide recommendations for improvements over the next 25 years. To ensure the 400 page technical document would accurately tell their Master Plan story and build support amongst all target audiences from decision makers to the customer, the District reimagined the document in a highly visual way by reinventing the key messages within a 10 page graphical brochure.

Transparency Is Just Telling It Like It Is – Isn’t It?

Nicki Pozos, Libby Barg

Barney & Worth, United States of America;

Ratepayers are telling utilities they want transparency in how decisions are made and projects are implemented. Technical professionals often interpret transparency as being based solely on facts, thinking of transparency as just the accurate transmittal of technical information. But to the public, transparency is not just about the information – it’s a feeling. One of the main barriers to feeling transparent is when information is complex and difficult to understand, even if it is accurate. It gives the feeling information is being occluded, even if that is not the intent.

This presentation will discuss approaches to convey in information in a way that is both technically accurate and feels transparent. The presentation will include audience interaction, having participants practice transforming complex information into easy-to-understand text.

Practical Field Techniques and Methods to Assess Secondary Clarifier Performance

Frank Dolemeyer1, Joyce Chang2, Theresa Gregonia1, Vince Chiu1, Kim Fries2

1Metro Vancouver; 2Jacobs; ,

In a secondary wastewater treatment facility, clarifiers are the final critical step for solids/liquid separation producing effluent that meets regulatory limits for total suspended solids prior to discharge. In-situ clarifier hydraulics are crucial to a clarifier’s efficiency and performance. Typical measures of secondary clarifier performance include effluent suspended solids concentration and solids capture efficiency at varying flow rates. Other clarifier performance indicators include surface overflow rates, solids loading rate, sludge blanket depth, and return sludge rate. This presentation covers the application of practical field techniques and methods on which operators can assess a clarifier’s hydraulic performance.

In 2001, the Water Environment Research Foundation (WERF) and Clarifier Research Technical Committee (CRTC) published a guidance document on protocols for evaluating secondary clarifier performance. The document outlines detailed steps for testing a clarifier and troubleshooting clarifier issues. Metro Vancouver operations staff have been regularly assessing the performance of secondary clarifiers at the Northwest Langley Wastewater Treatment Plant using the dispersed suspended solids/flocculated suspended solids (DSS/FSS) tests described in the WERF/CRTC protocol. In addition to the regular tests, Metro Vancouver also conducted a 2-month intensive test program in 2017 to further evaluate clarifier performance under different flow conditions.

This presentation will provide an overview of the test program, demonstrate DSS/FSS sampling techniques using a Kemmerer sampler, present two years of data, and highlight key lessons learned. The results from the 2017 intensive test program, including additional DSS/FSS test points beyond the standard WERF/CRTC protocol and dye test results, combined with microscopic observations of microorganisms, illustrate how test data can be used to assess a clarifier’s hydraulic performance and assist operators in identifying where to focus efforts on improving overall plant performance.

Stress Testing of a Secondary Clarifier with an Adaptive Inlet Structure

Mario Benisch1, JB Neethling2

1HDR Portland, OR , United States of America; 2HDR Folsom, CA, United States of America;

Conventional clarifiers are generally limited in their performance by the settling characteristics of the biological sludge and hydraulic conditions in the clarifier. In general, secondary clarifier (SCL) effluent total suspended solids (TSS) less than 10 mg/L are difficult to achieve consistently. The Hydrograv Adapt variable inlet structure (HA) changes that.

Unlike traditional inlet structures, mixed liquor is introduced near the bottom of the clarifier below the sludge blanket. In addition the inlet elevation and opening height adapts to the load thus always operating in ideal hydraulic conditions. Embedded in the functioning principal is the blanket filtration. Since MLSS is introduced near the bottom of the sludge blanket, all flow has to travel (filter) through the blanket. The results are impressive.

At Moers-Gerdt the average annual TSS concentration for 2017 is 1.5 mg/L. To investigate the performance of an HA clarifier under peak load conditions a full scale stress test was conducted at the Moers-Gerdt facility Nov 14th 2017. Pushing 100% of the plant through one of three clarifiers, effluent turbidity never exceeded 1.0 ntu and was closer to 0.5 most of the time.

The technology has the potential to reduce the compliance cost for utilities to meet lower effluent limits by improving solids capture in the clarifier. Upgraded clarifiers have demonstrated a 60% to 95% reduction of clarifier effluent solids. Full scale experiences show effluent from a HA clarifier can rival that of a sand filters. In fact, at two installations plant staff have since taken the effluent dual media filters offline as they are no longer required for compliance. To quote the lead Operator at Moers Gerdt, Guido Hammer “In my opinion this best innovation in wastewater treatment in the last 30 years”.

Designing Lagoon-Based WWTPs for <1 mg/L Ammonia in <34°F Water: The Case of Harrah, Washington

CJ Strain1, Ted Pooler2

1Nexom, United States of America; 2HLA Engineering and Land Survey, Inc., United States of America; ,

Ammonia limits are in place in nearly every corner of North America, and for good reason. But in small- and medium-sized communities—like Harrah, WA—who are reliant on lagoon-based wastewater treatment that was never designed for nitrification, operators and their consultants may not be certain of what works and what doesn’t when it comes to beating these limits.

This presentation will cover the causes of lagoon nitrification failure—particularly related to cold lagoon effluent that can fall to <1°C in winter—and the validity of options that purport to beat those limits year-round (including recent developments in MBBR-based technologies as well as SAGR post-lagoon nitrification). It cuts through marketing noise to discuss the common pitfalls when piloting new technologies and how to evaluate data sets. Further, it addresses the question of inevitable nitrate limits, and how lagoon-based WWTPs are uniquely suited to address them.

The conclusions will be drawn from the experience of hundreds of lagoon upgrades over the last 20 years, including the Harrah, Washington wastewater treatment plant, where HLA Engineering and Land Surveying, Inc. chose to implement the SAGR technology to retain the existing lagoon infrastructure and treat the 70,000 GPD design flow so the plant can beat its 1.93 mg/L Winter Ammonia objective. The presentation will examine the engineers’ decision-making process and what made SAGR technology the logical choice, as well as the challenges overcome in implementing the SAGR at the Harrah site, within their lagoons’ existing footprint.

The presentation will also draw on the data set collected from the Harrah site as well as additional years of data collected at a comparable site in Kennard, Indiana (for even greater context) which explain why, even in the face of their ammonia limit, their operators sleep easy. Kennard’s data shows that since commissioning in 2014, the site’s Ammonia levels have consistently measured well below that limit, averaging 0.17 mg/L while also producing BOD levels averaging 1.92 mg/L and TSS levels of 4.97 mg/L.

Soggy in Snohomish - Lagoon Nitrification via Biofilm Media 5 Years of Performance

Wayne Flournoy, Jeff Danner

Entex Technologies Inc., United States of America; ,

Lagoon systems are one of the oldest and most popular methods of wastewater treatment used today. They have remained appealing for both municipal and industrial treatment applications for their relatively low capital cost, low operating costs, and ease of maintenance. While aerated lagoons are typically well suited for carbonaceous biological oxygen demand (CBOD) removal, their susceptibility to inclement weather can make it difficult to maintain consistent biological nutrient removal. The City of Snohomish, Washington added fixed biofilm media in 2012 to solve a unique set of challenges in maintaining treatment at its wastewater treatment facility. While the plant’s average month daily flow is 1.2 MGD, maximum month daily flows can reach up to 7.9 MGD due to heavy rainfall events. High flows through the plant used to wash out the microbial populations responsible for ammonia transformation, making it difficult to maintain consistent nitrification. In 2012, the City completed a facility upgrade which included retrofitting its three partial-mix lagoons with a total of fifty-four (54) submerged fixed-film (SFF) modules, to improve CBOD removal and nitrification performance. To date, the SFF media system has proven to be an effective solution to the treatment issues presented by wet weather flows at the facility, as it quickly helped the plant meet or exceed its effluent criteria for CBOD and ammonia. In addition, the SFF system resulted in significant cost savings for the City, as it required less additional footprint and lower operating costs compared to alternative solutions.

This paper reviews the performance, effectiveness and economics over the 5-year span since the conversion.

Green Stormwater Infrastructure for CSO Control— A Cost-Performance Model to Address Uncertainty & Risk in GSI design

Alice Lancaster1, John Phillips2

1Herrera Environmental Consultants; 2King County Wastewater Treatment Division; ,

The King County Wastewater Treatment Division (WTD) is embarking on large-scale implementation of roadside green stormwater infrastructure (GSI) retrofits to help control combined sewer overflows (CSOs). To support this effort, an innovative model was developed that allows decision makers to account for uncertainty and risk in design.

The GSI cost/performance model allows comparison of various GSI retrofit options given variability and uncertainty in right-of-way conditions and infiltration potential. Based on block-scale user inputs, the model assesses feasibility, CSO reduction performance, and cost for a suite of GSI practices. The model can be run in a probabilistic mode that uses a Monte-Carlo simulation to evaluate performance for a range of possible inputs, providing the ability to address variability and uncertainty in parameters such as: effective impervious surface area draining to the street, shallow infiltration rate, deep infiltration well capacity, and unit costs.

The Excel-based model includes bioretention, walled bioretention, and curb bulbs with a range of infiltration approaches (infiltration to shallow soil and infiltration to deeper soil horizons using pit drains, drilled drains and deep wells). The model also includes proprietary filtration treatment (Filterra) to deep wells.

The probabilistic model utilizes Crystal Ball software and is being used to evaluate a range of typical retrofit scenarios anticipated for future WTD GSI projects. The results of this analysis will be used to develop tools to guide alternatives development and evaluation, such as cost effectiveness curves and decision flow charts. In addition, this work will address key questions to support programmatic siting and design guidance, such as “Which block typologies are the most feasible/cost effective for GSI retrofits?” and “In what surface and subsurface conditions are deep infiltration practices more cost effective?”.

This presentation will include a description of the model, the design tools developed using the model, and the resulting programmatic siting and design guidance.

Multi-Function/Use Stormwater Facilities - The Future of Stormwater Management?

Christopher May

Kitsap County Public Works (KCPW), United States of America;

Kitsap County Public Works (KCPW) has designed and constructed a number of stormwater management facilities that have included significant features address functional goals other than stormwater treatment. These functions include community gathering spaces (parks?), walking trails, wildlife habitat, and other aesthetic related uses. With the costs for regional stormwater facilities and stormwater retrofits increasing, gaining public support and acceptance for stormwater treatment has become more difficult. The public also expects more cooperation from the various branches of local government to improve project cost-benefit ratios and provide multiple uses for projects as a whole. Green stormwater solutions (GSS) provide a unique opportunity to incorporate open-space or community amenities into stormwater treatment facilities on a neighborhood or regional scale. This presentation will show examples of this concept and stimulate discussion of other multi-use/function approaches to public works projects of the future.

Sulfur Sequestration in Anaerobic Digestion Without the Use of Scrubbers

Tyson Schlect1, Doug Kelley2

1T-O Engineers, United States of America; 2Inland Environmental Resources, United States of America; ,

Sulfur can be a smelly culprit in wastewater treatment systems. It becomes problematic in its reduced form of hydrogen sulfide gas (H2S), to which it is converted via biotransformation in almost any anaerobic environment. H2S is commonly associated with collection systems and headworks, but is also a key consideration in anaerobic digestion systems, as it appears as a biogas constituent. When biogas is burned, H2S is converted to sulfur oxides and emitted to atmosphere. As sulfur dioxide is a primary contributor to “acid rain”, emissions can lead to rigorous air permitting limits. If biogas is utilized in an energy recovery system, the H2S can severely damage equipment.

Numerous biogas scrubbers are available on the market, but one simpler and more environmentally sustainable solution is often overlooked. Using fundamental aqueous chemistry principles, a regional food processor adopted a strategy to sequester sulfur in the liquid stream by raising the pH slightly in the anaerobic digester. This would reduce the concentration of H2S in the biogas at the source rather than cleaning it up later with a scrubbing system. Magnesium hydroxide (Mg(OH)2) was selected to achieve system buffering and pH increase because it provides stable digester operation and is environmentally sustainable.

The first fundamental principal at play is Henry’s Law, which states that if less H2S is present in the digester liquid, then less will be present in the biogas. The second fundamental principal is acid/base speciation in liquid, which means that as pH increases more of the total sulfur in the digester will be present as HS- rather than H2S. The overall effect of these two principles is that the higher the pH, the less H2S is in the biogas.

Comparison of Phosphorus Recovery Through Pre-anaerobic-digestion Brushite Precipitation And Post-Anaerobic-Digestion Struvite Crystallization

Zhongtian Li, Jerod Swanson

Centrisys/CNP, United States of America;

Phosphorus removal and recovery from sludge stream in water resource recovery facilities (WRRFs) bring multiple benefits including phosphorus recovery, digester and pipes protection, and improvement of sludge dewaterability. This study will evaluate two phosphorus recovery options through brushite (CaHPO4•2H2O) precipitation and struvite (MgNH4 PO4•2H2O) crystallization in terms of treatment process, phosphorus release and recovery strategy, and impacts on solids treatment processes.

Pre-anaerobic-digestion phosphorus recovery through brushite precipitation by CalPrexTM technology. The CalPrex system consists of three key processes. First, an acid phase digester is utilized for optimizing phosphorus release in sludge. Second, soluble phosphate is separated from sludge through a phosphorus stripping centrifuge, generating phosphorus rich centrate. Third, the phosphorus rich centrate is treated in controlled pH and calcium hydroxide dosage for brushite formation and precipitation. The phosphorus reduced sludge cake is recombined with a portion of the brushite clarifier effluent before piping to a methane phase digester.

Post-anaerobic-digestion phosphorus recovery through struvite crystallization by AirPrex® technology. The digested sludge is fed into a reactor located immediately after the anaerobic digester (AD). The reactor is equipped with air stripping; this will increase the pH value of the digested sludge. The addition of magnesium salts leads to the formation, and ultimately, to the sedimentation of struvite. The precipitated struvite crystals are extracted, washed and dewatered by a struvite washing unit immediately following the reactor. No additional chemicals or heat sources are needed to dry the product.

The objective of this study is to evaluate the performance of CalPrex and AirPrex pilot tests in terms of treatment process, phosphorus release and recovery strategy, and impacts on solids treatment processes. Both CalPrex and AirPrex pilot units are designed at the same hydraulic loading. The performance of dewaterability of acidogenically digested sludge and the anaerobically (methanogenic) digested sludge are compared. The phosphorus removal and recovery potentials are evaluated between brushite precipitation and struvite crystallization.

Enhanced Biological Phosphorus Removal Process for Achieving Extremely Low Effluent Phosphorus Levels

Bridget {Yueyun} Li Tse1,2, Per Halkjær Nielsen Nielsen4, April Gu2,3

1Black and Veatch, United States of America; 2Northeastern University, United States of America; 3Cornell University, United States of America; 4Center for Microbial Communities,Department of Chemistry and Bioscience,Aalborg University, Aalborg, Denmark;

U.S. EPA regulations are now implementing increasingly stringent wastewater phosphorus (P) controls to more areas across the country. The TMDLs for some sensitive areas (e.g. Spokane River basin) are as low as 0.05 mg P/L, and more facilities are faced with the extremely low P targets (e.g. 0.01 – 0.06 mg-P/L), which are near the limit of P removal technologies currently in practice. Enhanced biological phosphorus removal (EBPR) process is considered a promising strategy to simultaneously achieve sustainable P removal and P recovery, with economic and environmental advantages over traditional chemical/physical P removal technologies, especially for cases to meet compliance of extremely low effluent P levels. However, due to the yet insufficient fundamental understanding of the mechanisms involved in EBPR processes, there is still a lack of mechanisms-based design, model and optimization guidance, and the advantages of EBPR has not yet been fully realized.

In this study, we focused on systematically investigating the combined effect of two critical operational parameters, SRT and influent C/P ratio, particularly, to identify the key factors that govern the EBPR stability variation, using state-of- art and innovative microbial ecology tools that enable simultaneous examination and monitoring of both phylogenetic and metabolic/functional characteristics and dynamics in EBPR systems.

Our EBPR systems were demonstrated to be able to achieve < 0.01 mg P/L effluent phosphate level. Higher stability was observed with higher influent C/P ratio, and an optimal SRT range was revealed for each influent C/P conditions. The long-term P removal stabilities of our C-limited EBPR systems provided with relatively low influent C/P ratio were positively correlated with polyphosphate accumulating organisms (PAO) relative abundance, while the stability of those operated under relatively favorable conditions (i.e. C non-limiting condition with high influent C/P ratio) was found positively correlated with the overall EBPR phylogenetic diversity but not PAO or glycogen accumulating organisms (GAO) abundances.

Characterizing BPR Activity to Understand Overall Process Health

Gavin Bushee, Peter Schauer, Adrienne Menniti

Clean Water Services, United States of America;

Consistent and stable BPR is pivotal in meeting strict effluent limits and providing recoverable phosphorus downstream of the dewatering process. Historically, the BPR process can operate consistently for long periods of time, only to become upset during critical times of year. Developing a better understanding of the factors influencing the stability of the process is important so that different process configurations or corrective measures can be taken without relying on chemical phosphorus removal.

Factors affecting BPR include operational conditions, influent characteristics, availability of volatile fatty acids (VFA), rainfall, and competition for substrate with denitrifiers or glycogen accumulating organisms (GAO). However, readily available data for evaluating process performance is often limited to effluent phosphorus or sampling of the influent stream or mixed liquor, which is usually difficult or impossible to adequately use to predict process instabilities that lead to upsets. Extensive research and bench testing of phosphorus release and uptake has been performed at the treatment facilities to better characterize the BPR process and determine the most important factors affecting its stability.

Key findings of current bench testing indicate that:

• Batch phosphorus uptake rates of sludge from the end of the aeration zone can be substantial, indicating excess storage products (i.e. polyhydroxoalkoanate) remaining in the sludge.

• Phosphorus uptake rates are mainly a factor of PHA content and abundance of phosphorus accumulating organisms (PAO) (i.e. total PAO fraction) in the sludge.

• Batch phosphorus uptake rates correlate well with basin removal performance and VFA load, therefore, online measurements may be a useful tool in predicting process upsets and knowing when to shift VFA inventory. The status of an online uptake system developed at Durham will be presented.

• PAO/GAO competition is unlikely to be a current factor in BPR stability based on phosphorus release to acetate uptake ratios (P:HAc) and qPCR.

Success with a New Generation of Leaders

John Beacham, Monica Ott

City of Post Falls;

From 2014 through the present, the City of Post Falls experienced a major demographic shift in personnel. Many experienced professionals retired and carried with them decades of knowledge and experience. At the same time, the City is experiencing both a major growth phase and significant new regulatory obligations which necessitate staffing increases and major capital upgrades. The first of these presents the challenge of hiring candidates from the new generation for both new and recently vacated positions and the second puts a big responsibility on these newly-hired, potentially inexperienced candidates. Currently, the top four leadership position within the Wastewater division are held by employees under the age of 35, yet the department is facing the largest projects and most stringent regulatory requirements it has seen to date. Of the remaining Operations staff, all but one are over 40 which poses inter-generational challenges in forming a cohesive Utilities team. The City’s Utilities Manager will share his perspective on being hired into a leadership role supervising staff with greater years of experience. He will also share his experiences recruiting from a workforce with limited career experience. Filling one of the newest positions, the City’s Environmental Specialist will share her perspective on joining a department in a professional role with limited industry experience. She will share her experiences trying to gain respect, earn credibility and demonstrate value to the division. To meet the challenges successfully, a significant goal and subsequent accomplishment of the new generation of management within the Division has been to establish reputations as reliable professionals within the City. These efforts have paid off. In discussions with long-time employees morale is at its highest level in years and the Division sees strong support from the City Council on both projects and new initiatives.

Strategies to Build a Workforce of Women Leaders

Jennifer Price1, Courtney O'Neill2, Shailee Sztern3

1GHD; 2AECOM, United States of America; 3Seattle Public Utilities; ,

40% of women who earn engineering degrees quit the profession. This is a major challenge for all of our organizations. A majority of these women leave because of the organizational climate, characterized by non-supportive managers or co-workers and general incivility. Another reason tends to be that women don’t see any long-term potential for themselves in this industry. One former woman engineer quoted, “It’s hard to justify the long hours to go nowhere”. The infrastructure industry, similar to other technical industries, is still lacking in sufficient female leadership at the highest levels of organizations. Our industry has on average over 40% women in the workforce, yet on average there is only 10-20% women in leadership at the executive levels. Our presentation will address strategies for both public and private sector employers and leaders to increase the pool of women leaders at all levels of the organization and start to increase diversity in succession planning and leadership. We conducted multiple focused interviews of senior women leaders in our industry, on both the public and private sectors. We also included a few women in other technical industries. We asked each of these leaders to identify their keys to success, characteristics of strong leaders, and strategies they used to improve their leadership and navigate their career. We will focus on strategies that can be used by employees, managers, and executives to improve their own leadership and help increase the number of women employees at all levels. These could include effective mentoring, handling difficult conversations, and stepping into your leadership potential.

Ladies and Gentlemen Tip Your Cap For The City Of Portland Bureau of Environmental Services Wastewater Group's Systematic Condition Assessment Program

Mia Sabanovic

City of Portland/Bureau of Environmental Services, United States of America;

Condition assessment is vital for a comprehensive and robust utility asset management program. The Bureau of Environmental Services (BES) uses data generated by the Condition Assessment Program (CAP) to make strategic reinvestment decisions by systematically decreasing unforeseen asset failures and reducing overall business risk exposure. CAP is a two-way asset condition assessment communication conduit, from field experts to engineers to decision makers, and includes over 18,000 registered assets at two large wastewater treatment plants, 98 pump stations and appurtenances. The program is a comprehensive and proactive approach in defining the degree and pace of reinvestment required to meet and sustain optimal levels of service at an acceptable risk. The “super exciting” aspect of the program is that decisions are made on current information and there is a built in “means-to-madness” through a 2-level approach

Level 1 condition assessment includes visual and experience based assessment completed by operations and maintenance field technicians on a regular basis utilizing condition rating tables. Technicians communicate asset condition scores through the CMMS during preventive, predictive and corrective work order close out process or after completing inspection routes. After screening and prioritization, assets that have poor condition inspection scores are followed up with Level 2 condition assessment. Level 2 condition assessment entails a detailed analysis of the asset performance, invasive physical condition assessment, remaining useful life assessment, past failure history and performance. Level 2 condition assessment results in capital improvement project requests or modifications to the operational or maintenance strategies for identified assets to ensure business risk exposure reduction.

This presentation will describe how BES is realizing a culture set in life-cycle asset management that effectively integrates asset condition information to optimize asset reliability, extend useful life, and minimize asset life cost at an acceptable risk while meeting established levels of service.

Successful Asset Management Programs: A Sum of All Parts

Jeff Theerman

Brown and Caldwell, United States of America;

By nature, water utilities recognize and understand the need for asset management; most understand that a managed approach designed to wring the most life out of each asset is the best way to optimize costs and ensure reliability. To that end, many have invested in the various components of asset management like third party condition assessment and computerized maintenance management systems. Many utilities have in-house engineering expertise that drive capital projects through design and construction, and financial expertise for reviewing budgets and rates. This being the case, why does a fully functioning Asset Management program remain elusive for US Water Utilities?

The reality is that most utilities struggle with really understanding how the asset management elements fit together to achieve success. Utilities often focus on the discrete elements of asset management without considering the human interconnections that make-up of the program. While each element is important, it is the sum of all the connected parts and their ability to function together that makes a program successful.

Asset Management depends on a clear understanding of the interconnected elements and committed team of players that has embraced the need to change long held methods and approaches. The concepts are not difficult but putting them into practice is daunting. When utilities think of asset management only as a series of building blocks they can lose sight of the complex web of staff interactions that create value.

This paper describes many considerations that are often missing in utility asset management programs. Attendees will gain insight on the critical linkages between asset management program elements and explore a real-world example of how these linkages and the human players involved can spell the difference between success and failure.

Strategic Communications Connects the Dots and Defines One Water Journey

Holly Tichenor

Water Systems Consulting, Inc., United States of America;

The alternatives are evaluated. The treatment technology is proven. The schedule and cost are feasible. But, not all the dots are connected.

While agencies are working toward reliable and sustainable water solutions, achieving envisioned results require new degrees of collaboration, partnership, and communications. This shift is driven by many factors, including advancements in treatment technology, greater public awareness, impacts of climate change and more.

This presentation will utilize case studies from the drought epicenter, the Central Coast of CA, where in a very short period, utility leaders had to quickly assess and address traditional water management approaches to align stakeholders and close the water gap. We will look at 3-4 examples where strategic planning and communications is the One Water implementation connector.

• Multi-Section Strategic Plan Update. City of San Luis Obispo desired to make their Utility Strategic Plan (Plan) more relevant, actionable, and transparent to staff. The effort identified gaps impacting project and strategic plan use and implementation. A cross-department approach to align around a common vision and plan.

• Water Program Branding. The City of Pismo Beach worked collaboratively with its five agency partners to rebrand and improve communications around its $30M groundwater recharge program. The effort demonstrates the value of branding water with the community interest at the forefront.

• Communications for Funding Support. Partners within the Big Bear Valley have invested in communications support that simply conveys a complex story and the critical need to restore and protect this natural gem.

• Workshop Role Playing. The effort demonstrates how a role-playing interactive workshop approach has promoted water leaders to look at water challenges differently to arrive at better solutions.

In summary, the case studies demonstrate how strategic plans, frameworks, and effective communications is an essential ingredient for developing successful water solutions.

Leveraging Community Input to Define an Unlikely Path to Water Reuse

Matthew Gregg1, Nate Runyan2

1Brown and Caldwell, United States of America; 2City of Nampa, Idaho; ,

The City of Nampa, Idaho has been working for several years to define the preferred path to meeting increasingly stringent water quality regulations for their wastewater system. Acknowledging the magnitude of this decision and the impact to the community, the City elected to utilize a robust stakeholder engagement process to support the evaluation process conducted as part of their recently completed planning efforts. The goal of these efforts was to understand the community’s priorities related to water so that these could be represented in the alternatives analysis process for the City’s facility planning.

The City used an engaged group of approximately 60 citizens as the primary means of gather public input. Beginning early in the City’s planning process, this group helped shape the goals for the City’s upcoming investments by relating them back to the City’s Strategic Plan. Technical alternatives were developed and presented to the citizen group from this input and guidance. The City then described how each alternative aligned with the citizen and community’s goals and presented approaches to quantify this alignment (or misalignment in some cases) so that the community interests could be considered in parallel with the technical aspects of the project. This process lead the City to develop a water reuse strategy that supports the community’s interest to make full use of their water assets and support economic development within the City, a somewhat unexpected outcome at the outset of the process.

This presentation will focus on the City’s path to developing a water use program grounded in its community’s interests. Specific attention will be given to how the public process was administered to get feedback that could be incorporated into the technical alternatives evaluation.

Primary Filtration (PF) is an advanced primary treatment technology that can be used to replace primary clarification at wastewater treatment plants (WWTPs). Based on several pilot and demonstration projects, PF has been established as a treatment method to achieve significant capital and energy savings at WWTPs. PF was found to increase the primary treatment removal efficiency by an additional 50% over conventional primary clarification. Primary filtration achieves an overall 40 to 60% carbon reduction, depending on the influent characteristics. Resultant advantages of the PF process are:

1. Decreased aeration power consumption (approximately 25%) required for secondary treatment,

2. Increased energy production up to 30% in the anaerobic digestion process resulting from the high organic energy content of the volatile suspended solids removed by the filter,

3. Expanded plant capacity of about 30% by reducing the organic loading upstream of the secondary process,

4. Reduction of footprint required for primary treatment of approximately 75%, and

Pilot testing of PF for sidestream and primary filtration began in August 2016 and was completed in June 2017 at City and County of Honolulu Sand Island WWTP. Another 1-year PF demonstration testing using cloth depth filter was completed in December 2017 for Los Angeles County Sanitation District at the Lancaster WWTP. Following numerous pilot and demonstration PF projects, construction of the first full-scale PF installation was completed in June 2017 at Linda County Water District (Linda) WWTP (Olivehurst, California). The detailed evaluation of this first full-scale PF installation at Linda WWTP will provide significant information for wider implementation of this promising technology.

This presentation will provide an overview of the PF technology with its significance for the WWTP industry. Several case studies will be discussed in detail including the full-scale installation at Linda WWTP and demonstration and pilot projects at Lancaster and Sand Island WWTPs. Field performance data, operational issues, and projected cost savings will be presented.

Rushville, IN – First Cloth Media Filtration Case Study for Combined Tertiary Treatment and Wet Weather Flows

John Dyson1, Steve Gress2

1Aqua Aerobic Systems, Inc., United States of America; 2Donohue & Associates, Inc.;

After extensive use in tertiary applications for over two decades, cloth media filtration has now been adapted for wet weather treatment. Rushville, IN is the first full-scale CSO cloth media filtration system to be operational and started in July 2017. This new solution has emerged as a promising technology due to its many advantages compared to existing solutions. This wet weather/stormwater filtration technology offers a small footprint and is capable of treating extremely high solids while providing high quality effluent without the use of chemicals. This cloth media filter can be utilized in many wet weather/stormwater applications including sidestream CSO, SSO, or stormwater treatment and combination configurations. The combination configurations can be used in combination in tertiary filtration or primary treatment modes during dry weather conditions, but CSO/SSO sidestream treatment during wet weather events.

The presentation will cover the operational performance of the cloth media filtration technology during the first year of operation. Looking at the performance during dry weather conditions when the filter is operating in tertiary treatment mode for TSS and phosphorus removal. Then, the performance of the cloth media filtration system during wet weather event while treating both the secondary clarifier effluent flows and excess wet weather flows that are being blending around the secondary treatment process.

To validate this new wet weather filtration solution, many studies have been conducted on raw domestic wastewater and wet weather conditions. Pilot studies have been conducted at the Rock River Water Reclamation District (RRWRD) in Rockford, IL in 2014, Rushville, IN and other locations. The treatment scheme consists of fine screening and grit removal before the wet weather treatment system. These studies have documented the technology’s capabilities to achieve TSS and BOD5 removals of >80% and >45%, respectively. This high removal efficiency has been achieved without the use of chemicals.

This filtration technology is also a viable solution for primary treatment and tertiary filtration applications.

Optimizing Lagoon Based Treatment Systems for Improved BOD, TSS and Nutrient Removal

Tom Birkeland

Lemna Environmental Technologies, United States of America;

Meeting tougher regulatory requirements for BOD, TSS and nutrient removal including ammonia, phosphorus and total nitrogen can be a daunting task for any community, especially those with aging lagoon systems. Add in a cold climate where treatment is adversely affected by winter temperatures and many lagoon facilities struggle to stay in compliance with current limits or plan for future requirements. This talk will demonstrate how advancements in lagoon technologies, design and operations are helping communities to effectively meet their current and future effluent requirements.

Using wastewater treatment process design modeling software, lagoon treatment designs can be optimized for performance and reliability, especially for nutrient removal. The latest innovations in lagoon treatment use a dynamic wastewater treatment process simulation model, to analyze performance of existing facilities and the expected performance of proposed facilities. The models can explore the impact of various changes in loadings and temperatures and verify process design and performance before project implementation. Models may be manipulated to reflect the size, configuration, loading, aeration and effluent requirements for current or future facilities and are especially useful in predicting and troubleshooting cold weather performance and nutrient removal. Models enable designers to consider the effects of non-steady state factors such as peak flows, constituent loading, and ambient air and water temperatures, improving upon traditional steady state wastewater treatment process design methodology.

This presentation will focus on an updated approach for aerated lagoon based wastewater treatment and include an introduction to lagoon technologies, a brief discussion of current design methods, and several case studies showcasing how lagoon systems have been successfully upgraded in order to meet stringent effluent requirements for BOD, TSS, ammonia and phosphorus removal.

Acid Reign: Use of Peracetic Acid for Disinfection at the Snohomish, WA WWTP

Tom Giese1, Duane Leach2, Jeff Harmon3

1BHC Consultants, United States of America; 2City of Snohomish, WA; 3TMG Services; , ,

The City of Snohomish, Washington owns and operates a lagoon wastewater treatment plant rated for 2.8 million gallons per day that discharges into the Snohomish River. The City had been using chlorine gas to disinfect effluent and sulfur dioxide gas to dechlorinate the effluent prior to discharge. Although there are no projected capacity issues with the chlorine gas disinfection system, that system requires a number of improvements to replace old equipment and enhance safety. Furthermore, the City would prefer to avoid the safety concerns of handling and storing chlorine gas. For these reasons, the City had tested application of peracetic acid (PAA) as an alternative method of disinfection. The City conducted full-scale testing to confirm effectiveness and evaluate the economics and performance of PAA versus replacing the chlorine gas system with sodium hypochlorite and using sodium bisulfite for dechlorination. A representative of the City, City’s consultant, and the PAA vendor will discuss the process that the City went through to evaluate the application of PAA, select a vendor, conduct the testing, and obtain approval of this “new and developmental technology” from the Washington State Department of Ecology, including:

• A brief overview of the WWTP and the drivers for considering PAA.

• Ecology requirements for “new and developmental technology”.

• Overview of PAA disinfection.

• Initial sizing parameters and bench-scale testing.

• PAA vendor selection process.

• PAA system requirements and process contingencies.

• Testing and sampling protocol.

• PAA system performance and challenges.

• Overview of PAA testing results.

• Discussion of next steps for implementation.

King County has been implementing a combined sewer overflow (CSO) control program for over three decades. The County’s CSO program includes the construction of facilities to treat CSOs prior to discharge. Over the years, the County has had periodic issues at various CSO treatment facilities with consistently meeting discharge requirements for fecal coliform, settleable solids and chlorine residual.

The County is facing challenges of siting large CSO facilities in the urban area and rising costs for constructing facilities, The County is investigating innovative solutions that are operator friendly, fit within tight space constraints in highly developed portions of the City of Seattle and consistently meet the current regulatory requirements. The County would also like to incorporate newer technologies that not only achieve today’s water quality standards but also will meet future regulatory challenges.

Recently, the County and project team identified a new methodology for treating CSO discharges: using a combination of ceramic (silicon carbide) membranes and chemical coagulant commercialized by OVIVO. As a physical chemical process, this system can react quickly, activating within one minute. The County requested that Tetra Tech and Parametrix oversee a “live flow” site test of the OVIVO system, to assess its potential for addressing CSO conditions in the Seattle area.

This presentation will share the following with attendees:

• Process operation and key components;

• CSO simulation approach;

• Testing protocol and procedures;

• Results documented by an independent testing lab;

• Additional information needed;

• Lessons learned over the multi-day testing period, and;

• Why the County is now moving forward with a larger scale pilot program.

City of Spokane Sharp Avenue Porous Pavement Effectiveness Study

Marcia Davis1, Robin Kirschbaum2

1City of Spokane Integrated Capital Management; 2Robin Kirschbaum, Inc.; ,

The 2014-2019 Eastern Washington Phase II Municipal Stormwater Permit, Section S8.B, requires permittees to “collaborate with other permittees to select, propose, develop, and conduct Ecology-approved studies to assess, on a regional or sub-regional basis, the effectiveness of permit-required stormwater management program activities and best management practices (BMPs)”. Many Eastern Washington permittees worked collaboratively to meet this requirement by developing a ranked list of effectiveness studies.

The City of Spokane (City) proposed to implement the Sharp Avenue Porous Pavement Effectiveness Study to design, construct, monitor, and maintain a porous pavement system on an arterial street, Sharp Avenue, located in north Spokane. The City also proposed to collect data from the porous pavements with respect to durability, water quality (influent and effluent), and infiltration rates. Sharp Avenue is located in the Municipal Separated Storm Sewer System (MS4) basins that discharges to the Spokane River. The goals of the project are to:

• Gain a better understanding of stormwater runoff treatment capacity through the porous pavement profile

• Evaluate the effectiveness of the porous pavement systems with respect to durability, infiltration rates, and water quality

• Compare two different types of porous pavement: porous asphalt and pervious concrete

This presentation will discuss design, construction, monitoring, and lessons learned from past porous pavement installations in the City and from this on-going project.

Thermal Hydrolysis, how well do full scale systems really work?

Todd Williams

Jacobs, United States of America;

There is growing significant interest in the use of thermal hydrolysis technology in conjunction with anaerobic digestion to manage biosolids in the North America marketplace. This is being driven by the desire to obtain Class A exceptional quality biosolids, to improve the dewaterability of the biosolids and to reduce the amount of solids that subsequently must be managed while at the same time optimizing the use of existing digestion assets. Because of this interest, several thermal hydrolysis vendors are entering the marketplace. Cambi has developed the most operating facilities worldwide. In North America Cambi has one operating facility at DCWater since late 2014. The first North American chemical-thermal hydrolysis system offered by CNP - Pondus also began operation in Wisconsin in early 2016. Other vendors are aggressively working to enter the thermal hydrolysis marketplace in North America including Veolia with their Kruger Biothelys and Exelys offerings, Sustec/Turbotec, Haarslev and Lysotherm. Many claims are being made in vendor literature related to these technology offerings and only recently has more information about full scale performance been available.

The purpose of this paper and presentation is to provide an unbiased review of the various full scale thermal hydrolysis systems currently available in the marketplace and to provide comparisons of full scale performance of several operating systems as reported in the literature. 22 full scale thermal hydrolysis systems with published operational performance data have been reviewed and analyzed and will be presented to show comparisons of actual operating data. Correlations between feed solids type (primary vs. waste activated solids), volatile solids reduction achieved in digestion, dewatering performance, digester residence time, improvements in dewatering and volatile solids reduction performance after thermal hydrolysis was added as well as other relationships will be presented. This information will be useful for water resource recovery facility engineers, operators and owners when considering, planning and designing thermal hydrolysis technology with anaerobic digestion as part of a facility’s sludge management strategy.

Update on Biogas for RNG, Projects Around the Country

Jeremy Holland, Karen Bill

HDR, United States of America; ,

There is significant interest in reducing environmental impacts of wastewater treatment and recognizing the opportunities to reframe thinking of a wastewater treatment facility as a resource recovery facility. Water reuse and nutrient recovery have been focal points of this effort, but more recent opportunities have arisen that make anaerobic digestion and biogas use another attractive opportunity to improve the environmental footprint of wastewater facilities and increase the resources recovered from our municipal waste stream. Biogas provides an opportunity to generate renewable heat, electricity, transportation fuel, and even bioplastics. These opportunities can reduce the environmental cost of heat, power, or fuel from fossil fuel sources. And incentives are now available that will also provide significant revenue sources for communities to reduce operating costs and assist in capital projects. In addition to these onsite opportunities, many communities are recognizing the unsustainability of landfilling organics, and seeking ways to divert those organics. Wastewater facilities with existing digesters may have capacity to receive and process these organics, resulting in lower fugitive emissions at landfills and increased renewable fuels generated at the treatment plants. Fats, oils, and greases are also a maintenance challenge for collection systems. Grease trap programs that direct those wastes to treatment plants provide the benefit of reduced impacts due to overflows caused by blockage along with added organic feedstock to digesters for enhanced biogas production. This presentation will discuss the opportunities and challenges of implementing organics recovery and co-digestion to increase biogas production, along with the opportunities for use of the biogas to reduce energy consumption, greenhouse gas emissions, and transportation fuel usage. Some case studies of facilities that have implemented programs will be described and presented as well. The presentation will highlight the current status of renewable attribute programs such as the Renewable Fuel Standard and Low Carbon Fuel Standard, and any new programs that have been implemented. It will identify up and coming equipment for treating and/ using biogas.

Beat Ultra-Low Phosphorus Targets with Reactive Filtration: How Citronelle, Alabama consistently hits 0.02 mg/L

CJ Strain

Nexom, United States of America;

As Phosphorus-fed algae blooms plague many North American bodies of water, regulators are pressuring wastewater treatment facilities to meet ever-lower Phosphorus limits, down to micrograms per liter. Phosphorus levels can vary significantly from region to region, but many states across the USA are seeing limits below 0.1 mg/L, with some introducing limits between 0.01 and 0.07 mg/L. In 2015, Citronelle, Alabama's 1 MGD plant was facing one of the lowest—if not the lowest—NPDES permits in the nation: 0.022 mg/L.

This presentation delivers an overview of available techniques for phosphorus removal and how installations currently meet end-user limits. The goal in each application should always be to provide the most reliable treatment system while minimizing the technology’s capital and life-cycle costs; as such, the focus technique in this presentation utilizes reactive filtration. Rather than dosing system influent and allowing coagulated particles to randomly be caught up in the filter, reactive filtration coats the filter media with the substrate needed to adsorb contaminants and nutrients, helping ensure phosphates don’t pass through the filter while improving headloss profile through the system. The process’ continuous backwash then serves to recycle unused reagent and assist in regenerating the adsorptive, reagent-coated media.

Case history, design considerations, and lessons-learned will include data sets up to and including its first full season of compliance to <0.067 mg/L TP at Grangeville, Idaho, as well as Citronelle, Alabama’s chosen solution: a continuous-backwash upflow sand filter-based reactive filtration installation (known by the Blue PRO trademark) which is producing <20 μg/L TP effluent. As an added bonus, for those looking for a complete nutrient removal solution, the presentation will also briefly show how the sand filter-based process is compatible with the Blue NITE process, which uses a similar filtration design to achieve Total Nitrogen reduction down to 3 to 5 mg/L through denitrification.

Achieving Ultra-Low Level Phosphorus at the Star, ID Wastewater Facility

Eric Roundy

Keller Associates, United States of America;

Low-level phosphorus effluent requirements are becoming a reality for many communities in Idaho. Star Sewer & Water District’s (SSWD) effluent discharge permit will soon require a seasonal monthly total phosphorus limit of 0.07 mg/L (as P). In addition to phosphorus removal, SSWD also received a more stringent ammonia limit, and is expected to receive a temperature limit in the future.

In preparation for these stringent limits, SSWD has studied and investigated a number of alternatives. SSWD owns and operates a membrane bioreactor (MBR), which provides a high quality effluent; however, they were concerned about chemical phosphorus removal negatively impacting their biological treatment. SSWD’s goal was to meet the new discharge limits while still producing effluent capable of meeting Class A recycled water requirements.

Recently, bench and pilot tests have been performed on the preferred technologies. This presentation will focus on the results of the pilot tests, which included chemical phosphorus removal using a rare earth solution. Other more commonly used chemicals, such as aluminum sulfate, were also tested. A description and comparison of the removal chemistry will be provided. The effect of the chemicals on nutrient removal will also be discussed.

The results of the pilot tests indicated that:

• The low-level phosphorus limit could be achieved with either aluminum sulfate or rare earth

• Ammonia and total nitrogen reduction can still be achieved while using chemical phosphorus removal

• Sludge production and dewaterability can be important factors in technology selection

• Pilot testing low-level phosphorus at the plant can provide significant savings

How to Grow your Career through Mentoring

Alena Thurman, Lara Kammereck

Carollo Engineers, United States of America; ,

Many believe that the key to career success is a combination of ambition, ability, and opportunity. While these factors are important, research shows that one of the biggest factors in career success and leadership development is actually mentorship. What’s more, it’s not just being mentored that shapes one’s career – mentoring others is equally, if not more, important for one’s career. This presentation discusses this research and highlights a successful mentorship between two female engineers.

It’s no stretch to believe that being mentored positively affects one’s career. Employees who are mentored experience faster growth in their career and greater career satisfaction. However, giving one’s time to mentor others is equally important. In a study of over 160 engineers, the most productive employees were those who consistently gave more to their colleagues than they received. In another study of those in sales, the top performers who averaged 50 percent more revenue than other employees were “givers”. Since giving is an intrinsic part of mentorship, this research holds true for mentors as well.

Over the past seven years at Carollo Engineers, Inc. the relationship between Lara Kammereck and Alena Thurman is proof that giving and receiving mentorship works. In fact they have found that mentorship is most successful when the parties are both receiving and giving mentorship.

Making the Case for Diversity - Is It Part of Your Strategic Plan?

Ann Hajnosz

Harris & Associates, United States of America;

The water utility industry has grown increasingly complex and challenging, making it a great time to be in this industry! But there is a catch to this rosy outlook – we are in a war for talent. Demographics point to increasing retirements from the field and an acute shortage of professionals entering the field. Furthermore, water professionals need to be equipped with skills and knowledge that many us who have been in this industry for decades may not have valued or even thought much about. Attributes such as “team player”, “emotional intelligence”, “connecting the dots”, “stakeholder engagement” and other so-called soft skills are rising to prominence in an industry that is finding its footing in a world that is suddenly “curious” about everything water-related or more appropriately, “One Water-Related”. The ability to engage, connect and resonate with an increasingly diverse customer base and associated stakeholders is one of the biggest challenges of our industry. Without stakeholder support, the best technical solutions will be difficult to implement; difficult to fund and could possibly jeopardize our goals of ensuring public health and safety and being stewards to our natural resources. We need water utility staff who understand these challenges and embrace the idea of finding solutions amidst an array of diverse ideas.

If attracting and retaining the right staff to address these industry challenges is not part of your organization’s Strategic Planning process – it should be! Specifically, how will we as an industry respond to the war for talent?

This presentation will:

• Report on current findings around the idea that successful organizations are positioning themselves to attract and retain increasingly diverse employees

• Define diversity in the eyes of successful organizations – it’s not just what you look like!

• Define success for these organizations – is it really just about the bottom line?

• Suggest ways for those of us in the water utility industry to win the war on talent

• Recommend specific steps to incorporate diversity into your Strategic Plan

Risk-Based Asset Management Communication Tool

Michael Comeskey1, Neil Jenkins2

1City of Boise Public Works; 2Jacobs; ,

The operators and mechanics know that an asset is broken and will stop working for the last time any day now. Duct tape and baling wire have extended its life and the engineering department has had it on the list to replace for years. Now, with stiff competition throughout the utility for limited resources, how do we get decision-makers to prioritize replacement funding?

The City of Boise has instituted an asset management approach to help close the gap between what operators and mechanics live with, what engineering staff knows about and would like to solve, and what makes it high enough on the decision makers list of priorities to fund. Based on the best practices in the International Infrastructure Management Manual and the ISO-55000 standard, the refreshed strategy relies on inputs like condition assessment to break down communication barriers by creating a common language based on risk. The project was multi-disciplinary within the utility, involving staff from operations, engineering, maintenance, and finance. Starting with a desktop review of all assets to determine how critical each asset is to the overall utility goals and objectives, participants then walked through the facility to validate the workplan in the field. Recognizing the importance of consistent and repeatable assessments, the team then brought in technical experts from outside the organization to train utility staff and perform quantitative condition assessments. The information gathered was processed and reviewed before communicating the results throughout the organization. The risk prioritization process allows team members at all levels to understand where the limited resources should be used and aligned the plan and priorities across the workgroups. As a result, capital spending was targeted to maximize risk reduction across the utility.

An Electronic Operator’s Manual On SharePoint - Wikipedia Style

Joel Borchers1,2, Prashant Sinha1, Brad Rumbaugh1, Matthew LaForce2,1

1Clean Water Services, United States of America; 2Clackamas Community College;

A cloud-based Electronic Operator’s Manual (EOM) was implemented in order to consolidate reference materials and bring new hires up to a level of competence in a limited amount of time.

Plant Documentation covers a wide array of materials; vendor O&M manuals, As-Built Drawings from past projects, equipment information, Control Descriptions, Standard Operating Procedures. In addition to these reference items, a narrative along with videos, pictures and drawings show how the various processes operate and what pieces of equipment are used to implement those processes. When new projects are underway in certain areas of the plant, resources are directed to that particular area of the plant to insure the information that is generated during the project is captured and that the information needed is created.

The EOM design in similar to Wikipedia in that users have the ability to add content to the EOM themselves. When new content is first entered into the EOM, the new content is available to only the person who created the new content along with a team of Subject Matter Experts. The Subject Matter Experts will review, and if needed modify, the new content prior to approval. Once approved, the new content is viewable to the general audience. The ability to add content to the EOM is designed to create a sense of ownership among the Operations staff.

The Electronic Operator’s Manual has also integrated an online learning platform based on a documented list of tasks, skills and information that an Operator needs to master in order to operate certain areas of the plant.

Even though the EOM contains some specific information on equipment, plans are underway to integrate the Computerized Maintenance Management System in the near future.

Cloud Hosted SCADA and Asset Management Automation

Rick Patton

Advanced Control Systems, LLC, United States of America;

Problem: Rural towns are finding it more and more difficult to support water and wastewater delivery systems, in part, due to the increasing trend for their youth to migrate to larger cities. With fewer recruits to fill operations positions, Cities have less tax revenue and less maintenance personnel forcing them to do more with less. Many small towns and privately owned operations are considering automation to enable fewer operators to manage and maintain their systems through remote monitoring, control and preventive maintenance. However, automation itself has traditionally required maintenance, so a solution must be found to reduce operational overhead without adding maintenance.

Solution: Cloud hosted solutions are the way of the future. Software as a Service (SAAS) is being adopted by nearly any company that has historically provided tactile software products. The customer will no longer “own”, but rather “pay to use”. The reasons for the providers to move to the cloud are many, but the value proposition for their customers is the same – unlimited scalability, high reliability, zero maintenance, zero obsolescence, remote support and unlimited access.

Conclusion: Cloud hosted solutions can be provided with a lower initial price when compared to traditional and, over their lifespan, provide superior value and with lower overall cost of ownership.

Thinking Past the Pipe: Innovation and Community Engagement on the Georgetown Wet Weather Treatment Station

Kristine Cramer1, Cari Simson2, Bibiana Ocheke-Ameh1

1King County Wastewater Treatment Division; 2Urban Systems Design; ,

Sited in the industrial-residential heart of Seattle’s Georgetown neighborhood, King County’s Georgetown Wet Weather Treatment Station (GWWTS) is a combined sewer overflow control facility designed to protect the Duwamish River from future stormwater and wastewater pollution. The Wastewater Treatment Division (WTD) saw the facility siting, design, and construction as an opportunity to build strong relationships with a historically underserved population in a growing neighborhood, on the banks of a Superfund site. The project reimagined community engagement for a new era in which Equity and Social Justice is a top priority, the idea of “neighborhood” extends beyond the project site, and a project incorporates community initiatives into its plans.

WTD achieved these community engagement goals by:

• Bringing business leaders and residents together in a community Design Advisory Committee to guide the site’s architecture and landscaping.

• Implementing a robust Equity and Social Justice Action Plan to ensure the County fully considered the area’s equity opportunities.

• Leveraging community-driven initiatives to help further protect water quality, including:

o Partnering with Urban Systems Design (USD) to install cisterns and rain gardens at a popular neighborhood grocery.

o Working with the City of Seattle, USD and Seattle Parks Foundation to seek grant funding to revive a long-desired neighborhood project connecting the community to Georgetown’s only riverfront park.

o Funding a community-initiated Green Wall along a traffic arterial to improve air and water quality.

o Joining forces with a small non-profit and local elementary school to improve educational opportunities and create art beautifying the project site.

• Prioritizing local hires in the construction contract.

Achieving big results requires big effort. Together, a committed outreach team, a supportive project manager, and an engaged community created a project that will improve water quality beyond the bounds of the treatment station. The GWWTS approach is a model for all large infrastructure projects seeking to leverage capital investments to build better infrastructure and enduring positive relationships with stakeholders and ratepayers.

Engaging the Public with Water Renewal

Colin Hickman, Cindy Busche

City of Boise; ,

In 2016, the City of Boise embarked on the mission of rebranding the wastewater treatment facilities. The City recognized that the public did not have an understanding of the work we do and that our previous model of citizen understanding and engagement needed to change. As we moved to a resource recovery focused operation, we needed to tell our story – or risk having someone tell it for us. Now, two years later, the City has developed a multi-pronged approach to generate community awareness to gain community understanding and support. At the foundation of the community engagement process was the rebranding to identify our organizational personality, defining purpose and positioning statements and ultimately determining a new name for the utility. Then a series of public communication campaigns and direct citizen outreach strategies were implemented. In addition, changes to the programming and exhibits at the Boise WaterShed Education Center, which traditionally reached youth, expanded its offerings to target adults in our community. We are excited to share these outreach and education strategies with you to take home ideas to implement in your community.

Engaging the Community to Plan Boise’s Water Future

Colin Hickman1, Natalie Podgorski2, Matt Gregg3, Haley Falconer1

1City of Boise, United States of America; 2Atlas Strategic Communications; 3Brown and Caldwell; ,

The City of Boise (city) is developing a long-term facility plan for its Water Renewal Services. Traditionally, facility plans have engaged stakeholders at the end of the planning process to endorse the proposed plan. Boise is aiming to do things differently. The city has sought to proactively engage and educate a diverse group of stakeholders throughout facility planning. The city has made ratepayer input a crucial element of the planning process to ensure decisions made today reflect the priorities of the community for the next several decades.

The city has employed various stakeholder engagement tactics that provide for both breadth and depth of feedback. To gather feedback and rich dialogue on water and energy concepts, the city started by holding a series of ratepayer focus groups. These meetings allowed the city to gain insight into the baseline knowledge of ratepayers and gauge reactions of future opportunities. The city also held a meeting with key stakeholders, including business leaders, environmental groups, associations serving some of Boise’s most vulnerable citizens, and neighborhood associations, to educate them on future opportunities and solicit feedback. Finally, the city developed an online survey and hosted two community workshops along with a Facebook Live town hall to gain broader feedback from even more residents. Throughout these efforts the city received praise for involving the community and an appreciation from the outreach participants in having a role shaping the city’s plan.

This process can serve as a roadmap for other utilities looking to more effectively engage with community stakeholders. This presentation will highlight why Boise placed such an important emphasis on community feedback, how the communication strategy was developed to align with the planning outcomes, and the tactics utilized to engage with ratepayers.

City of Post Falls, Idaho – Membrane Tertiary Treatment Pilot Study for Low-Phosphorus and Reuse

Michael Conn1, Mark Esvelt2, Ben Carleton2, Monica Ott3, John Beacham3

1J-U-B Engineers, Inc, United States of America; 2Esvelt Environmental Engineering; 3City of Post Falls; , ,

The City of Post Falls, Idaho owns and operates a secondary treatment Water Reclamation Facility (WRF) utilizing enhanced biological phosphorus removal (EBPR) to treat municipal wastewater. Under an NPDES Permit, reclaimed water from the Post Falls WRF is discharged to the Spokane. New NPDES limits and a compliance schedule targeting a reduction of CBOD5 and total phosphorus (TP) are being driven by a TMDL for dissolved oxygen in the downstream receiving water. To meet loading caps of 255 lbs/day CBOD and 3.19 lbs/day TP, concentration limits will decrease as future flows increase to <6 mg/L CBOD5 and <50 ug/L TP, arguably some of the most stringent limits in the nation. The City has undertaken an 18-month pilot study to test three MF/UF pressurized membranes in a tertiary filtration application to determine the ability of the systems to meet the new effluent requirements (and for future Class A reuse). In addition to the membrane pilot study, three high-rate clarification (HRC) systems were tested for pre-treatment to the membranes, including solids-contact clarification, dissolved air flotation, and plate settlers. During planning for the pilot study, pressure membranes (downstream of the HRC’s) were evaluated for the application, specifically targeting systems’ capable of handling heavy chemical doses. Further, research of full-scale facilities identified very few systems operating with EBPR followed by tertiary membranes targeting ultra-low TP. This lack of industry knowledge led the City to undertake a robust pilot protocol to enhance their knowledge of their potential full-scale tertiary system that they are targeting for full-scale. The paper will present the operational parameters tested including variable influent conditions, coagulant dosing, laboratory procedures and results for ultra-low TP. The conclusions of the study will be presented along with how the pilot study data was utilized to inform the membrane procurement, and design for the full-scale system.

Practical Considerations for the Full-Scale Application of a Membrane Aerated Biofilm Reactor (MABR)

Tom Johnson, William Leaf

Jacobs/CH2M, United States of America;

For any new technology, there is often a large leap that is required to move from pilot scale testing to full scale application. The development of new technologies has typically followed an “S-Curve” in the wastewater industry. As discussed in the recent Water Resources Utility of the Future Annual Report (2015), this acceleration of the S-Curve has led to the emergence of an Innovation Ecosystem. Within this ecosystem, technology developers, consulting engineers, utilities, and universities are collaborating to better define risks associated with innovative technology. This collaboration results in a deeper understanding of technology risks and benefits, and increased implementation of innovative technologies that provide clear resource reduction and recovery benefit for a utility. The membrane aerated biofilm reactor (MABR) technology development has actually had an extended bench scale and pilot scale period. Several manufacturers are now developing commercial scale MABR reactors. The challenge now is accurately identifying whole plant impacts of the MABR, and developing practical design standards for both the MABR and the ancillary components.

VCS Denmark manages the Ejby Molle facility in Odense, Denmark and recently completed a full-scale MABR demonstration project. The drivers for VCS with the incorporation of the MABR is to: 1) provide energy efficient total nitrogen (TN) removal, and 2) increase peak wet weather capacity. The whole plant impacts of incorporating the MABR in the full-scale pilot are documented. The optimal location for the MABR in the existing bioreactors is presented. A 40-percent net energy reduction was estimated in the activated sludge process. The average effluent TN was not impacted, but the overall annual TN discharge was reduced given the improved process stability. The peak wet weather capacity increased by 45 percent. A detailed process modeling (with Dynamita's SUMO) effort is also completed, with calibration and validation against the MABR performance.

Beads to Brine to the Bank: Piloting Electrodialysis for Reuse of Concentrated Brine

Katerina Messologitis

Stantec Consulting, United States of America;

Anionic exchange resins are becoming more widely used in advanced industrial wastewater treatment and to target specific constituents for potable reuse. Anionic resins can be regenerated to 99.9% recovery with NaCl, but leave behind a saline waste stream, referred to as brine. This brine contains left-over NaCl, as well as desorbed inorganic and organic anions (SO42-, HCO3-, HS, etc.) from the feed water. Dealing with this brine has always been a problem when trying to do large-scale treatment; especially with increasingly strict regulations.

Fortunately, compounds in the brine can be reclaimed if properly separated: NaCl for direct reuse in the regeneration process; and HS as a bio-stimulant for crop growth. Previous investigations have highlighted the efficiency of using electrodialysis (ED) technology to achieve the separation of 1) NaCl with mono-selective membranes and 2) divalent ions from HS with non-selective membranes. However, little was known about the effect of high organic loads from the brine on operations causing fouling or spacer clogging.

The purpose of this presentation is to share pilot-scale findings, which evaluated the long-term feasibility of ED technology for treatment of an anion exchange brine, including NaCl and HS recovery. ED treatment with mono-selective membranes took place over a six-month period while recording operational data and quality of the by-products. Results demonstrate that ED treatment with mono- and non-selective membranes is an innovative process that can be effective at targeting the recovery of resources from concentrated waste streams.

Brief Biography and/or Qualifications
Katerina has a Masters degree in Civil Engineering from the University of New Hampshire. She conducted a pilot study on the feasibility of using electrodialysis for the recovery and reuse of concentrated brines from advanced water treatment.

Katerina currently works at Stantec primarily with a team of process engineers who operates a proof of concept pilot plant testing the efficacy of an industrial wastewater treatment and reclaim facility. Katerina applies and builds upon the skills learned during her thesis work to understand and synthesize the results from the current pilot project she is working on.

City of Prineville Crooked River Wetlands

Brett Moore

Anderson Perry & Associates, Inc., United States of America;

The City of Prineville’s Crooked River Wetlands Complex demonstrates a new approach to dealing with wastewater. Constructed for just $8 million, a fraction of the $62 million price tag of a previously recommended mechanical treatment plant, the complex utilizes natural processes found in the wetlands to further treat reclaimed water. Designed to operate entirely by gravity, the wetlands offer habitat to numerous plants, wildlife, waterfowl, and insects that support a healthy ecosystem. The nearly 5 miles of trails built throughout the complex also double as a biology and wildlife laboratory for area schools and a recreational get-away for visitors.

The wetlands in the complex were designed to augment the flow of water into the adjacent Crooked River. After the water is polished by the microorganisms growing on the plants in the wetland cells, the water is cooled as it flows underground into the Crooked River, providing as much as 2 million gallons per day of clean, cool water to aid in the reintroduction of steelhead and salmon.

As with most innovative ideas, this approach met with a fair amount of skepticism from regulatory agencies during the permitting process. Anderson Perry and the City conducted a number of studies to convince the agencies that this approach would not adversely affect area groundwater and the City agreed to meet extremely rigid monitoring requirements and increased water quality standards in order to secure permits.

Since beginning operations, the system is exceeding the stringent permit requirements and has helped pioneer a new permitting process and regulatory agency mindset for other communities and engineers who are interested in this non-traditional method for treating and disposing of wastewater. This project proves that treating wastewater can provide more to a community than smelly ponds or energy-consuming treatment plants, and can benefit the environment and provide recreational and educational experiences at the same time.

Clean Water Services constructed a 95-acre Natural Treatment System (NTS) adjacent to the Forest Grove Wastewater Treatment Facility (WWTF) in Forest Grove, Oregon, in 2017. The wetlands complex provides additional treatment of the secondary-treated wastewater effluent from the Hillsboro and Forest Grove WWTFs. As part of the NTS, an intensified vertical flow wetlands (VFW) was installed after the WWTF to achieve nitrification; the VFW was chosen to achieve significantly lower energy and maintenance costs.

A pilot-scale system was operated to determine the media type and optimum design parameters for a full-scale VFW. Six-foot-deep columns were filled with rock media with a high ammonium exchange capacity to facilitate biofilm growth. Effluent from the Forest Grove WWTF was supplemented with ammonia-nitrogen to ~20 mg nitrogen/L and dosed onto the columns in 5-centimeter-depths at set intervals using siphons. Pilot testing results (presented at the 2014 PNCWA Conference) showed ammonia removal rates of 93 to 98 percent when operated under loading rates of 1 to 16 m/d under either of two operational flow conditions: vertical flow or flood-and-drain flow.

Based on the results of the pilot-scale testing, 12 VFW cells with a horizontal area of about 55,000 square feet were constructed at the NTS. The 6-foot-deep cells were filled with ¼-inch to ½-inch river rock with an ammonium exchange capacity of >40 mg/kg. The VFW was designed to treat up to 14 MGD.

Full-scale testing is underway and results will be presented. Data including examination of loading rates and operational flow conditions on removal efficiencies will be presented along with a description of the final full-scale design and construction process. The full-scale removal rates will be compared to the pilot-scale results.

Treatment Wetlands for Nutrient Removal at Small Facilities

Jack Wallis1, Otto Stein2

1Wallis Engineering; 2Montana State University;

As water quality regulations become stricter, small facilities face significant challenges to providing cost-effective wastewater treatment. Treatment wetland systems are becoming increasingly attractive due to their ability to provide a high quality effluent at a fraction of the cost of conventional wastewater treatment systems. The Montana State University Treatment Wetland Lab Group recently designed and constructed two vertical flow treatment wetland systems in Montana in response to new regulatory requirements. A pilot-scale system was constructed at the Bridger Bowl Ski Resort to demonstrate nitrogen removal in anticipation of a nitrogen TMDL, and a full-scale system was constructed at the Ennis National Fish Hatchery to meet the requirements of a new Concentrated Aquatic Animal Production General Permit.

Both systems receive high strength wastewater: the Bridger influent is high in ammonia nitrogen and chemical oxygen demand from kitchens and restrooms, and the Ennis system receives solids rich wastewater from raceway cleaning. Both systems are two stage vertical flow wetlands, with design features tailored to specific wastewater characteristics and treatment requirements. The Bridger system has been optimized for nitrogen removal over four operating seasons, and has shown consistently high COD removal (95%) and nitrogen removal (up to 75% depending upon operating conditions). The Ennis system has been operating for only one year, and preliminary results have shown high removal efficiency of COD (98%), TSS (99%), TN (59%), and TP (95%).

Treatment wetland systems are particularly well suited to rural applications, where land area is available, but funding for capital improvements and operations and maintenance is limited. These results show that these systems can be a cost-effective solution for small facilities when high levels of treatment are required, and conventional systems are cost-prohibitive.

From Stormwater Monitoring to Adaptive Management: Getting the Most Out of a Permit-Driven Effectiveness Evaluation

Andy Weigel

Brown and Caldwell, United States of America;

Solutions for reducing pollutant loads in urban stormwater runoff are almost never a one-size-fits-all proposition. Advances in design of Green Stormwater Infrastructure, proprietary treatment systems, and innovative policy strategies have grown at an exciting pace in recent years. With a wealth of solutions, it can be difficult for public entities managing stormwater infrastructure to collect and analyze the various data and information needed to make sound decisions when selecting solutions for specific stormwater management needs. Monitoring data collected for permit compliance alone may not be adequate to answer these questions.

The Ada County Highway District (ACHD) is the lead agency for the only Phase I MS4 Permit in Idaho. ACHD shares permit compliance and stormwater management responsibilities with five other permittees to cover a 58,000-acre permit area that includes the cities of Boise and Garden City. In 2017 ACHD completed an intensive two-year data collection effort in a small residential subwatershed draining to an infiltration best management practice (BMP). Monitoring and modelling results were used to evaluate the effectiveness of this widely used BMP.

The evaluation included:

• Continuous flow and rain monitoring covering 55 rain events;

• Flow-weighted composite water quality sample collection for 6 rain events;

• Modelling of BMP pollutant removal, source loads, and stormwater runoff volume using the Source Loading and Management Model for Windows (WinSLAMM); and

• event-based qualitative observations.

The presentation will provide information on how the results of this evaluation are being used to refine runoff volume and pollutant loading estimates for larger, more complicated, subwatersheds throughout the permit area, and inform updates to BMP design guidance. The presentation also includes a discussion of how the results of this effectiveness evaluation and other permit-driven studies and evaluations are being used to guide the next phases of data collection and planning efforts to achieve higher pollutant load reductions in urban stormwater runoff.

1Murraysmith, United States of America; 2City of Newberg, Yamhill County, Oregon, United States of America; ,

Despite the building boom underway in the Pacific Northwest, stress prevails within the capital budgets available to municipal agencies. Resource demands from regulatory requirements, a saturated bid climate, active community members, right-of-way encroachments, and franchise utility conflicts all compete for infrastructure improvement funding.

The City of Newberg commenced a corridor safety upgrade in 2015 on a prominent collector route. Upgrades involved improving multi-modal safety through introduction of bike lanes, sidewalks, lighting, enhanced pedestrian crossings, and speed appropriate geometric roadway design. During the process, Murraysmith and the City identified multiple synergetic opportunities along the way to incorporate stormwater management, fish passage upgrades, right-of-way acquisition and utility undergrounding while managing a deficit in CIP funding.

This presentation will help attendees:

1. Identify stormwater opportunities for projects considering similar safety improvements

2. Provide budgeting assumptions for stormwater improvements relative to existing CIP’s and master plans

3. Inform public involvement campaigns to show rate payers tangible results

4. Review construction options available for rapid assembly fish passage structures

Moneyball for Biosolids Dewatering

Kelly Brown

BDP Industries, Inc., United States of America;

Problem Statement:

It is a common problem in the wastewater industry for a plant wanting to go from ponding or liquid field application of waste sludge to dewatering followed by drying or land application or haulage to a landfill. In accomplishing this process change the dewatering step is critical. If the discharge moisture is too high the landfill won’t take the waste, the energy balance of a Thermal Dryer is primarily a function of moisture, so the overall economics of the project are significantly impacted by the performance of the dewatering stage. What steps should be taken to insure the dewatering process is achieved?

What is typically done is pilot testing with small scale dewatering units. This article will cover the belt press and screw press options and the analysis to use that based on established filtration theory will develop bid specifications that insure the acquired dewatering equipment will meet the process objectives. A perusal of dewatering bid specifications shows few incorporate the specifications items that should be reference if basing the equipment selection on dewatering theory and the pilot test results.

Approach:

This article will cover a recent pilot trial for determining equipment sizing on a project and go through an analysis of the test results based on filtration theory so that specifications are written that will insure the desired process objectives are met. What are the equipment specifications that relate to filtration theory and process performance, they are in order of their importance:

F

1. Filtration Area

2. Feed Distribution

3. Gravity Section Control

4. Cake Pressure / Time Under Pressure

5. Drive System: Speed / Control

The article will go through an analysis of all the filtration data that can and should be taken and demonstrate how using filtration theory the bid specifications can be generated that will insure desired process objectives are met.

City Of Moscow Solids Management Alternative Feasibility Study

Casey Bryant, Kenny Sheffler, Kirsten Dolph, Nicole Tompkins, Cody Sprague

University of Idaho, United States of America; , ,

This project investigates an upgrade to the solids handling of the City of Moscow’s Water Reclamation and Reuse Facility (WRRF). Currently, waste activated sludge (WAS) is dewatered and transported to Latah Sanitation where it is composted to achieve Class A biosolids status. This is a costly method of solids handling which has few opportunities to realize resource recovery. Additionally, Moscow forgoes primary clarification – opting to treat all influent wastewater in its activated sludge basins.

In this study, anaerobic digestion is considered due to its ability to produce biogas. Biogas, rich in methane, can be used with combined heat and power (CHP) to provide electricity and heat to the WRRF, with the potential to offset operational costs and contribute to achieving resource recovery. Three different high-rate digestion alternatives were considered: single stage, acid-gas phased, and thermal hydrolysis pretreatment coupled with a single stage digester. Due to the complexity and uniqueness of the Moscow WRRF, using thermal hydrolysis to pretreat WAS before digestion proved the best of the three alternatives. However, when compared to the current operations, the disadvantages outweighed those of the current operations resulting in a final recommendation of a “no-build”.

Unlocking Idle Capacity in Old Digesters

Patricia Tam, Chris Muller, Tadd Giesbrecht

Brown and Caldwell, United States of America;

Increasing digester capacity is one of the costliest capital improvements in a wastewater treatment plant. This could take the form of adding new digester tanks, converting to an enhanced digestion process, or upgrading the thickening process. Of these, thickening process improvements could provide significant capacity gain at a cost much lower than the other approaches. This case study is related to the recent upgrade at the Central Kitsap Treatment Plant (CKTP), which includes upgrades to both liquid-stream and solids-stream processes.

The digestion system at CKTP treats primary and waste activated sludge (WAS) generated at CKTP, as well as secondary sludge generated at three other, smaller plants operated by Kitsap County. The two existing anaerobic digesters were approaching capacity and it was not possible to safely and reliably take one unit out of service for maintenance for extensive periods. In addition, the existing boilers could no longer beneficially use the biogas, so that the biogas was routinely combusted in a flare and wasted to the atmosphere.

As part of a larger plant upgrade, the thickening scheme was changed from co-thickening in two existing gravity thickeners to separate thickening of primary sludge thickening in the gravity thickener and WAS thickening in a new rotary drum thickener (RDT). This results in digester feed sludge at about twice the percent solids compared to that prior to the upgrade and doubling of the solids processing capacity of the digestion process. The thicker digester feed sludge also allowed for a new, more efficient energy strategy for the plant. A new combined heat and power (CHP) system was included in the upgrade, which provides beneficial reuse of the biogas, significantly reduces the use of fuel oil while meeting the system process heating needs and producing power, and reduces greenhouse gas (GHG) emissions.

Toward Achieving Mainstream Nitritation with Post-Anoxic EBPR

Jason Mellin

University of Idaho, United States of America;

Due to the potential for significant energy savings, achievement of stable nitritation for treatment of municipal WRRF mainstreams has received increasing research attention in recent years. Despite this attention, practical implementation by full scale facilities remains difficult. Specific challenges include lower wastewater temperatures, lower influent nitrogen, and variable influent loading, as compared to conditions realized in the most conventional sidestream treatment (i.e., ANAMMOX). Moreover, achieving stable nitritation within a biological nutrient removal process is hindered by additional factors, including competition for nutrient resources between different microbial groups. Recent research at UI has indicated, however, that a nitritation process coupled to EBPR in a post-anoxic configuration is viable and holds the potential for significant energy savings while achieving low effluent ammonia, NOx, and phosphorus concentrations. Furthermore, this process has the potential to provide a microbial source for bioplastic production, thereby further advancing the Resource Recovery concept. This presentation will discuss research performed at the University of Idaho on this EBPR process, with a focus on operating parameters, aeration and ammonia control strategies, process resiliency, and relevant microbial species interactions and metabolisms. In addition, the potential benefits and feasible implementation of this process at full scale facilities will be discussed.

Optimizing Volatile Fatty Acid Filtrate Extraction from Fermented Primary Sludge

Austin Carnes, Ron Gearhart, Zane Custer, Tony Harmon

City of Boise, United States of America;

The West Boise Water Renewal Facility was found to be constrained in its capacity to biologically remove phosphorus due to a limited supply of volatile fatty acids (VFAs), the preferred food source of phosphorus accumulating organisms. West Boise’s supplemental VFAs are produced by side stream primary sludge fermentation. A VFA rich filtrate is extracted from the fermented primary sludge (FPS) using rotary screen thickeners (RSTs). An optimization study of this extraction process was undertaken to determine if the supply of VFAs delivered to the treatment process could be increased. It was hypothesized that the thickened, fermented primary sludge (TFPS) that was being sent to digestion contained significant residual VFAs. To test this hypothesis, several samples of TFPS were obtained, diluted with deionized water, mixed, and the liquid fraction extracted using a pilot screen of the same material as the RSTs. Analyses of these samples showed VFA concentrations as high as those of the filtrate already being delivered to treatment. As a result, a two stage extraction pilot test was initiated. FPS was pumped through an RST, in which first stage extraction took place. It then discharged into a hopper along with dilution water. The contents of this hopper were pumped to a second RST in which second stage extraction took place. Testing of the filtrate from prior to and during the two stage extraction pilot showed an increase in VFA extraction of 677 pounds per day, a 48.5% increase. After the two stage extraction pilot, effluent dissolved reactive phosphorus from the best performing aeration basin fell by 70%. Plant effluent dissolved reactive phosphorus fell by 10%.

Heating Primary Sludge for Increased Volatile Fatty Acid Fermentation

Jana Otero, Adrienne Menniti, Peter Schauer

Clean Water Services, United States of America;

The Durham Advanced Wastewater Treatment Facility has been practicing biological phosphorus removal (BPR) for over two decades. The facility relies on a primary sludge Unified Fermentation and Thickening (UFAT) process to augment the influent Volatile Fatty Acids (VFA) and support BPR. The process currently needs to be expanded because the solid residence time (SRT) available is too low to provide adequate VFA production when wastewater temperatures are low. A capital improvement project to expand the UFAT process is scheduled for completion in 2022. As an interim solution, primary sludge heating is being installed to increase VFA production.

Preliminary bench-scale testing will develop the start-up and operational plan for the full scale heating. Two temperature controlled jacketed reactors will be used to operate continuous flow, bench-scale fermentation at temperatures ranging from 15-30 deg C and SRT ranging from 1-5 days. Testing for each condition will be conducted for longer than three SRT to reach steady state operation. Influent primary sludge TS, reactor pH, soluble VFA concentration, and effluent TS will be monitored.

Year-round operational data already shows that increasing the primary sludge temperature from 15 to 20 degrees C almost doubles the VFA produced. Heating the primary sludge should stabilize VFA production throughout the year and promote more stable BPR. This is exceptionally important in the early months of the summer permit season when BPR is highly VFA deficient.

This presentation will review the full-scale operational data that supports the potential benefit for heating the unit process, the bench-scale testing results, and the implications the heating project has on the overall facility expansion. The following key questions will be addressed:

• What SRT and temperature combination produces the most stable performance for VFA production?

• With sludge heating, what design SRT should be used for fermentation capital expansion design criteria?
