• Facility will triple North American drinking water UV capacity

NEW YORK, NY, Oct. 7, 2008 -- The world's largest ultraviolet disinfection facility has begun construction. A joint venture of Malcolm Pirnie/CH2M HILL is serving as the construction management team for the New York City Department of Environmental Protection's Catskill-Delaware Ultraviolet Disinfection Facility.

Located in Westchester County, New York, the facility will use 56 low-pressure, high-output UV reactors to treat an average of 1.3 billion gallons of water daily and will have capacity to treat more than 2 billion gallons daily. Scheduled for completion in September 2014, this single facility will triple the North American drinking water UV capacity.

"This is a landmark facility within the drinking water industry," says Paul Whitener, CH2M HILL's project manager. "We are proud to be partnering with Malcolm Pirnie and the NYC Department of Environmental Protection to provide high-quality drinking water to the DEP's 9 million customers."

New York City has the largest unfiltered surface water supply in the world, delivering more than 1.3 billion gallons of water daily to 9 million residents in New York City and the upstate area. Through gravity flow, the Catskill and Delaware aqueducts meet the majority of this demand.

Other teaming partners include URS. The project designer is a joint venture of Hazen and Sawyer/CDM.

Headquartered near Denver, Colo., employee-owned CH2M HILL is a global leader in engineering, procurement, construction, management and operations for government, civil, industrial and energy clients.
