Full Description

This article discusses the innovative process which the City of Seattle used to develop a new treatment facility, its first water filtration plant. Rather than use a conventional design-bid-build approach, the city opted for an alternative design-build-operate (DBO) model for its Tolt treatment facilities. The new facilities will increase system reliability and flexibility by allowing continuous operation of Seattle's Tolt source through periods of high turbidity. It will also improve system yield and allow long-range compliance with anticipated regulations. The authors discuss Seattle's experience over the complex, 18-month procurement process, including the challenges faced and steps taken in the DBO approach. Includes reference, tables, figures.
