Black & Veatch and McCarthy Building Companies are joint-venture partners teamed to deliver the design-build portion of a design-build-operate (DBO) contract for the 80-mgd Lake Pleasant Water Treatment Plant. Our team is a subcontractor to American Water Services, which will manage the $336 million DBO contract awarded by Phoenix in August 2003 and operate the facilities for 15 years.

The project consists of raw-water intake structure, pumping station and large-diameter pipeline to deliver raw water 1.5 miles to the 225-acre treatment plant site. Innovative, high-tech treatment elements include ballasted flocculation, ozonation, filtration, secondary filtration provided by granular activated carbon (GAC) contactors, and ultraviolet disinfection (UV) followed a 40-million gallon buried finished-water storage reservoir and finished-water pumping to the distribution system. Our project scope includes design, construction, startup, testing, commissioning and securing all permits for design, construction and operation. Construction is planned for July 2004 and delivery of finished water to the city's distribution system is scheduled for February 2007.
