Water Utility Selects WEDECO Advanced Treatment Technologies To Purify Urban Runoff

In February 2010, the Dempsey E. Benton Water Treatment Plant (DEBWTP) added 16 million gallons per day (MGD) of capacity to the water utility operated by the city of Raleigh, North Carolina. The project, situated on 55 acres in the neighboring town of Garner, North Carolina, represents a milestone in the utility’s history.

The lack of rain combined with a surging population in Raleigh and the surrounding Research Triangle Park area stretched the existing treatment plant to its limits. By 2009, the facility members at DEBWTP started working with an engineering consultant to design a second plant.

WEDECO UV disinfection was added to the end of the treatment train to enable the plant to move away from exclusively relying on chemical disinfection and allowing the plant to comply with more stringent federal disinfection byproduct requirements.
