PROJECT: ASR Program

Beaverton, Oregon

Since 1993, GSI personnel have worked with the City of Beaverton to develop its ASR program and have assisted with obtaining the second ASR limited license permit issued in the state. Services have included retrofitting an existing deep basalt groundwater production well for combined production and ASR, and the design and construction oversight of three new deep groundwater ASR/production wells in the Columbia River Basalt Group aquifer. Combined, the three ASR wells meet a significant percentage (more than 25 percent) of the City’s peak summer demand by supplying up to 6 million gallons per day. The City has operated the ASR wells in full-scale operations mode since 1998 and GSI is performing the ongoing system monitoring and providing monthly operational updates. GSI also has added the new ASR wells as additional points of appropriation to the City’s existing water rights so that the City can use these wells to pump native groundwater if needed.
