Harbour Storm Pump Station reduces energy levels by 15%

Opus worked with the City of Port Coquitlam on their Harbour Storm Pump Station.

The station has a design pumping capacity of 2.4 m3/s with two Spaans Babcock Archimedes screw pumps. The inherited disadvantage of conventional screw pumps is that the pump discharge must be located above the highest flood level in the receiving water course, even when this flood level occurs infrequently.

The Harbour Storm Pump Station has been designed to discharge above the 200 year Pitt River flood level of 4.4m geodetic (this is about 0.6m below the existing dyke crest). To reduce the discharge head a lower discharge opening with a sliding gate was provided resulting in a reduction in energy demands by about 15%.
