This article presents Wilmington, Delaware's program for water distribution system improvement. Wilmington's Department of Public Works developed and implemented an integrated multiyear program in 2003 to replace and rehabilitate its water distribution network. The program uses a multi‐objective project investment optimization model based on data from water main condition assessments, hydraulic performance analyses, valve exercising, and fire hydrant testing. Geographic information system (GIS)‐ based data models of water main breaks and water quality complaints, combined with hydraulic‐performance simulation models, are being used to select and prioritize asset renewal projects.
