Seattle Public Utilities is reimagining the planning process for combined sewer overflows (CSO) and stormwater improvements through the Longfellow Starts Here (LSH) project by endeavoring to make planning accessible and meaningful to the community served by this project. Whereas traditional options analysis has centered on technical feasibility and cost minimization approaches with sparse community engagement on leading options, the LSH team is shifting the planning approach to begin with community and co-create an infrastructure vision through simplified planning tools that demystify drainage and wastewater infrastructure. One tool, the Drainage and Wastewater High Level Planning Tool, is a Microsoft Excel based calculator that reports the cost and water quality performance of various user defined infrastructure scenarios in real time. Specifically, the user selects a suite of CSO reduction and water quality treatment options and the tool reports the planning-level cost, CSO volume reduction and pollutant reduction to Longfellow Creek. The intent of this tool is to facilitate simple, iterative planning so that community can collaborate with SPU to “co-create” the project and engage in dialogue around trade-offs and benefits of various options. The LSH team hopes this tool, through meaningful community engagement, will promote unconstrained creativity and help to elevate optimal strategies by removing the historical bottlenecks in infrastructure planning from modeling and cost analysis given that these calculations are performed automatically by the tool. This presentation will provide a summary of the scenario planning tool’s intended uses, an overview of the back-end calculations and assumptions, and a real time test drive of the tool to showcase its performance.

The City of Portland Bureau of Environmental Services (BES) Columbia Blvd Wastewater Treatment Plant (CBWTP) was first constructed in 1952 and continued to expand in later years. Many process pipes and plumbing systems are original to the plant’s construction and have often been the forgotten brethren of the CBWTP. The majority of the pipes have not been inspected internally during their lifetime or assessed for their condition and remaining useful life (RUL). The CBWTP has experienced an increase in pipe breaks in recent years causing process areas to be taken down and creating a detrimental impact on plants operations and a sharp increase in financial expenditures. Frequent breaks and leaks also impact operations and maintenance resources as piping systems are continuously patched to ensure reliable operations of the treatment plant.
BES Condition Assessment team has engaged with Kennedy Jenks consultants to prioritize, inspect, and assess plant process piping helping move BES towards proactive management of its pipe assets. The primary goal of this project is to identify BES’s risk exposure due to these aging pipe assets to enable tailored and sustainable long-term replacement/rehabilitation strategies.
This presentation will outline the vision and drivers for this project, along with sharing success stories and how other utilities can adopt similar programs. Attendees will learn about developing a truly integrated asset management solution, from identifying pipe assets, managing these process piping assets in CMMS, bringing GIS tools within the plant fences, developing risk and prioritization tools, using advanced condition assessment technology and conducting this with careful coordination with a busy plant’s scheduling restraints. Finally, the presentation will focus on creating a cultural of change in managing assets, one that proactively inspects piping systems and avoids unforeseen breaks and leaks through effective risk communication long after the team members have moved on.
Brief Biography and/or Qualifications Steven Dutschke is a reliability and data intelligence engineer at Kennedy Jenks. Steven has spent the last 10 years working to improve operations and maintenance programs through the application of analytics and asset management solutions in the water and oil and gas industries in Australia, Canada and the United States.
Mia Sabanovic, P.E. is an Engineer III at the Portland Bureau of Environmental Services (BES). She has over 15 years of civil engineering experience in public utility sector. She has been actively engaged in Asset Management Program in the City of Portland for the past 10 years. Mia leads a dynamic group of analysts and planners at the Colombia Blvd Wastewater Treatment Plant in the pursuit of improved management of BES assets through the application of programmatic maintenance and condition assessment.
