Rockaway Beach Pump Station, Rockaway Beach, OR
|
At the Rockaway Beach wastewater treatment plant we designed new effluent pump station to pump plant effluent through the new ocean outfall. We designed the horizontal centrifugal pumps and the land portion of the force main connecting to the ocean outfall. The design required addressing the low head conditions and included the design on special valves to allow the pumps to operate efficiently. A new concrete wetwell was designed inside of the existing plant building. Also included was designing the replacement pumps for the vacuum-primed trickling filter effluent pumps which pumped into the activated sludge basin. We assisted in the bidding process and provided periodic inspection services for the pump stations. We also wrote the operation and maintenance manual for the pump stations.
