This project replaces the current treatment facility of drinking water for the Chinook Water District. Located in the hills overlooking the Columbia River and the Town of Chinook is a new “State of the Art” Water Treatment Facility.

The water source for this community comes from an open reservoir where a new Pumping Station facility was constructed on the existing gravity out fall line and then pumped via a new raw water transmission main to the new treatment facility. The new facility consists of a new building, clearwell, standby power generation, and a series of ponds. Inside the new treatment building is a Pall microfiltration package water system, instrumentation, and another pumping system to convey the finish water via a new pipe line to the existing reservoirs.
