The plant currently serves 400,000 customers with an initial treatment capacity of 80 million gallons per day (mgd) and is expandable to an ultimate capacity of 320 mgd.

The Lake Pleasant plant was completed for the city of Phoenix by the design-build-operate (DBO) team comprised of the 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.

Phoenix Councilman Claude Mattox, who serves as the vice chair of the National League of Cities Energy, Environment and Natural Resources Steering Committee, congratulated the team on the accomplishment. “Thanks to the efforts of the partners and our city engineers, this state-of-the-art water treatment plant will serve our growing community well into the future,” said Mattox.

The new plant, which is the largest integrated DBO project in North America, was designed to blend seamlessly into the desert landscape without disturbing the natural beauty of the area. As a result, 95 percent of the habitat was preserved in its natural condition.

The plant incorporates the latest developments in modern water technology and automation, which will benefit the residents of Phoenix.  The design-build process included sustainable features that lay the groundwork for future customer growth and development, expanded capacity and emerging treatment technologies. The team also successfully focused on developing the water treatment plant with streamlined, efficient operations.

“A key to the success in achieving our goals was to combine all resources under one roof, which enabled a collaborative work environment,” said Dave Mahaffay, senior vice president and West region managing director for Black & Veatch’s global water business. “All parties involved were focused on delivering the project on time and within budget, as well as on ensuring operational excellence in safety and construction management.”

According to Bob Knochenhauer, senior vice president of operations for McCarthy’s Southwest Division Water Services Group, “The team’s collaborative approach was critical to the effective management of each phase of this complex project. It allowed for construction to start two months ahead of schedule and a budget reduction of $30 million, positioning both the team and the community for success.”

The treatment process design incorporates seven independent barriers for pathogens, virus and bacteria removal while typical treatment plant designs incorporate three to four barriers. Selected water treatment processes – such as high-rate ballasted flocculation, ozone, granular activated carbon contractors and ultraviolet – achieve superior operating and cost efficiency with numerous inventive improvements specific to residents’ needs, the local environment and available resources.

The national award was presented at the DBIA Annual Conference and Awards Ceremony held recently in Las Vegas.

WASTEWATER TREATMENT

“The sheer number of MEP tie-ins involved is staggering on this project…everything we do impacts multiple processes, making coordination the key.”

— John Pinkston, facilities superintendent, city of Chandler

A serious commitment to planning and partnering is a must as construction continues on the $75 million expansion of Chandler’s award-winning treatment facility.

When complete in summer 2009, the expanded plant will treat and recycle 15 million gallons of wastewater per day (from the current 10 million gallons per day). The expansion involves the construction of a new process building, tanks, basins, water reservoir, expanded odor control systems, piping and associated equipment—much of it tying into the existing plant’s MEP systems. McCarthy has completed or is in construction on $1 billion in water/wastewater facilities in the Phoenix area—and the Chandler plant represents the first where all process mechanical trade work will be performed by McCarthy labor forces (McCarthy has self-performed critical path trades such as concrete for decades). A critical factor in the planning involves long-lead equipment, much of which needs to be specified and ordered a year or more in advance to meet project deliveries.
