Water Works II, a $275-million water treatment plant currently under construction in Detroit, is redefining the way that such projects are let and built. In 1980 the city initiated a program to rehabilitate and upgrade its existing plant, a 320 mgd (1.2 million m�/d) facility originally constructed in 1924. The study showed that replacing the plant would be more cost effective, especially if the water authority used a design/build/maintain approach. To improve its comfort level with this more hands-off approach, the city decided that each bidder could have up to three confidential meetings with the owner to ask questions and float ideas. All bidders had one idea in common: Draining and reusing an existing 300 million gal (1.1 million m�) underground concrete reservoir as the site for the new plant.
