The Clark Regional Wastewater District (District) Board of Commissioners awarded a $0.6 million contract to Clark and Son’s Excavating, Inc. of Battle Ground, Washington for the restoration and upgrade of the Union Road Pump Station.

Located along NE Union Road, near NE 159th Street, the pump station serves a growing population of more than 3,000 people along the I-5 Corridor. Construction is scheduled to begin in in mid to late July 2019 and be completed by the end of the year. The project is funded from connection charge revenue, which is collected from new development.

Built in the early 1990’s near the banks of Whipple Creek, today the station pumps approximately one-half million gallons-per-day (0.5 MGD) of wastewater. The improvements at the station include installing all new mechanical and electrical systems, including the addition of a redundant power supply on-site, and site improvements. The existing station will remain in operation throughout construction.

“We are proactively making incremental investments in the collection system, like at Union Road Pump Station. Over time, all stations will be restored. This helps us fulfill our commitment to providing affordable and reliable service,” said Heath Henderson, District Engineer.

Construction activity is planned to be contained on the site, with no work planned in the roadway. Therefore, traffic impacts to the traveling public along NE Union Road should be limited.
