Cherry Creek Diversion Pump Station

A Key Component of the Rueter-Hess Water Supply System
Douglas County, Colorado

As part of the Parker Water and Sanitation District's 30-year plan to convert from groundwater to more sustainable renewable surface water supply and treatment, we designed a pump station, inlet channel, and mechanical bar screens on the banks of Cherry Creek in approximately six months. An air-filled bladder located in the creek diverts treated wastewater effluent blended with native surface water into the pump station—a process known as indirect reuse. Large steel gates restrict oversized debris from entering the facility and two eight-foot mechanical bar screens are equipped with chain-driven debris-removal hooks. The pump station contains five, 4,160-volt pumps with variable-frequency drives capable of producing 4,750 horsepower to convey up to 50-million gallons of raw water to the reservoir every day.

Our structural design included a concrete sedimentation channel, influent channel, wet well, and pump house. We designed approximately 15,800 feet of 48-inch welded-steel pipe, which required steady state and transient hydraulic modeling, appurtenance design, thrust restraint design, and tie-ins to existing pipelines.
