The Lake Pleasant Water Treatment Plant in Phoenix, completed by Black & Veatch and McCarthy Building Cos., has earned a special award from the Design-Build Institute of America.

The 225-acre treatment facility near the southeastern tip of the lake has been awarded the 2008 National Design-Build Award from the Design-Build Institute of America (DBIA) in the “water/wastewater over $15 million” category.

The Lake Pleasant plant was finished in 2007 for the City of Phoenix. It was completed by the design-build-operate (DBO) team of Black & Veatch-McCarthy joint venture, design-build team and American Water Enterprises Inc., a subsidiary of American Water (NYSE: AWK), which is the largest investor-owned U.S. water and wastewater utility company.

The plant is serving 400,000 customers with an initial treatment capacity of 80 million gallons per day. It is expandable to a maximum daily capacity of 320 million gallons.

The design-build process included expandable features allowing future customer growth and development, expanded capacity and new treatment technologies.

The plant’s treatment processes incorporate seven independent barriers for removing pathogens, viruses and bacteria, compared to three to four barriers in typical plant designs.

The new plant, called the largest integrated DBO project in North America, was designed to blend into the desert landscape. About 95 percent of the habitat was preserved in its natural condition, company officials said.
