Dayton Water Executes Successful “Proof-of-Concept” Pilot for Buried Pipe Assets' Risks and 50-Year Capital Improvement Plan (CIP)

The City of Dayton (Ohio) Water Department (Dayton Water) is determined to develop a long-term CIP, and a more systematic approach, tools and processes that will better define the need and fund the proactive repair and replacement (R&R) of their water and sewer pipes. They see this as a first step in implementing asset management, and have now performed a successful “Proof-of-Concept” (PoC) pilot project for those assets, including development of a 50-year capital improvement plan (CIP) for them. This case study paper is intended to help other utilities that are just getting started with, or are contemplating initiating asset management and capital planning programs, and it will present:• the method Dayton Water used for assigning risk scores to their water and sewer system linear assets in less than two months (with most performed during 3 workshop-days),• the risk scoring approach used to prioritize projects by pipe asset groups and reaches,• the method used for selecting prioritized projects using diminishing return on investment principles, and• the integration of level of service criteria to further prioritize, select and schedule CIP projects over multiple planning periods
