Maturing your Asset Management Program: Lessons from the front line, to the bottom line

The Discovery Clean Water Alliance has developed an Asset Management Roadmap to guide the improvement of managing the regional collection system and treatment facility assets. To develop the roadmap, the Alliance undertook a Comprehensive Asset Management Review and Assessment to evaluate the Alliance’s current and desired position along a maturity spectrum in 38 asset management theme areas.
A multi-year program of discrete asset management initiatives were identified to close gaps between current practices and best asset management practices. This program will bring the Alliance into alignment with desired asset management maturity that will improve reliability,cost efficiency and focusasset management efforts to provide the most benefit.
Following the Roadmap development, the Alliance immediately recognized that a comprehensive risk analysis of all significant assets was required to make measurable progress in the next biennial budget period. Through a series of facilitated workshops with engineering and O&M leadership, each major asset (building, pump, equipment, etc) was scored for likelihood and consequence of failure. The resulting “criticality” score for each asset was then ranked for action. This process, called Initial Criticality and Condition Assessment (ICCA), is a simple, cost effective process that could be replicated by many utilities to quickly identify the most critical needs.
This presentation will explain in detail the practice of developing the Asset management Roadmap, and the practical ICCA process used to identify needs based primarily on input from front line O&M staff. Utilities of all sizes can benefit from the lessons and practices implemented here and following this example of the “80/20 Principle”.

Bridging Condition Data Gaps with Unmanned Vehicles
Gary Skipper, Tony VanHaverbeke, Mike Metcalf
Brown and Caldwell, United States of America; ,
In 2017, America’s Drinking Water and Wastewater Infrastructure were given grades of D and D+, respectively, by the American Society of Civil Engineers. While critical pieces of water infrastructure are aging and deteriorating, many municipalities scramble to address growing demand and budget pressures. As a result, utilities are increasingly reliant on new tools and technologies that allow them to bridge gaps and do more with less.
Unmanned aerial, surface, and submersible vehicles, coupled with new data visualization techniques to improve data utilization, are helping to provide utilities with the critical condition assessment information they need to strategically rehab their facilities and stretch their dollars further. Unmanned vehicles have the potential to significantly improve the cost, speed, safety, and quality of condition assessments in the water, wastewater, and stormwater sectors. When equipped with advanced sensor payloads such as lidar, sonar, multispectral, and thermal imaging, the unmanned vehicles provide insights not previously possible. When employed to reduce or eliminate the need for manned inspections of tanks, culverts, pipelines and other infrastructure, they can significantly improve productivity and value.
Throughout this presentation we will share experiences, results, and specific examples from projects with the City of Tacoma, California DWR, City of San Jose, and others where we used a variety of unmanned vehicles and advanced sensors to answer tough questions. We’ll also share approaches to avoid “data overload” through improved data interfaces to allow for faster and more informed decisions about what repairs are necessary and enable utilities to be more strategic with their capital budgets.

The Big Payback: Portland’s Innovative Approach to Pump Station Investments

The City of Portland Bureau of Environmental Services operates 97 wastewater pump stations within their service area, including thousands of assets to track and maintain. The Pump Station Improvement Plan had been in place to prioritize capital spending; however, this process was manually executed and heavily rooted in institutional knowledge. Organizational changes provided an opportunity to evolve the program into an automated system. Partnering with Water Systems Consulting (WSC), the Bureau decided to re-envision its approach to pump station asset management to achieve these aims by creating the Pump Station System Plan.
WSC and BES established multiple key goals of the program. The primary driver of the project and ultimate output would be a Capital Improvement Program that prioritizes projects by comparative business risk. Several innovative strategies were implemented:
· Development and piloting of multiple digital tools to streamline field data collection
· A Condition Assessment Program that leverages routine operator activities to continually update condition information
· Automating a criticality analysis to prioritize critical assets
· Analysis of BES capital projects to predict costs of an unplanned failure
· Utilizing operating data and GIS to predict impacts of sanitary sewer overflows
· Establishing a “living” system plan that presents annualized risk for each station in a system-wide dashboard
· Refining key performance indicators to flag heightened risks such as health and safety hazards or technological obsolescence
A robust data management plan is essential to successful implementation. WSC sought to leverage existing software and tools to promote sustainable procedures and continuity in operations. However, challenges arising from data access, compatibility, and quality required a realistic approach to evaluate the short and long-term data integration effort. Our presentation will describe methods used to develop and maintain system tools to provide attendees with an understanding of how they can be scaled to provide benefits to systems of all sizes.
