Status: Current project
Project Category: Water
Project Estimated Cost: $15,500,000
Aquifer Storage and Recovery (ASR) is a way of storing drinking water underground, then pumping it out when it is needed. Constructing ASR Well No. 5 will expand ASR capacity by 2 million gallons per day (mgd) and will increase the reliability and capacity of the water supply both for the City of Beaverton and indirectly for our Joint Water Commission (JWC) partners. An increase in 2 mgd during average peak season water demand will provide for an equivalent supply of potable water to approximately 15,800 new Beaverton residents, which can be used for emergency purposes or when the water supply from the city’s primary JWC source is interrupted.

ASR Well No. 1 reached the end of its useful life and was converted to a monitoring well in 2013. ASR Well No. 5 will replace and offset the loss in aquifer storage recovery capacity from existing ASR Well No. 1 and add new pumping capacity of an additional 1 million gallons per day (mgd) of potable water. The ASR No. 5 well was drilled to a 24-inch diameter in 2016-2017 and will yield a total peak-capacity of 2 mgd. Staff completed preliminary design work for the project in FY 2018-19 using IFA (Infrastructure Finance Authority) funds from the State of Oregon and the US Environmental Protection Agency (EPA).The existing Sorrento Pump Station, built in the 1960s, is on the same project site and adjacent to the newly drilled ASR Well No. 5. A key element of the project is seismic resiliency. Since the Sorrento Pump Station is not seismically-resilient in the event of a major earthquake, the project will demolish the Sorrento Pump Station and build a single seismically-resilient pump station facility that encompasses the pumping functions of the former Sorrento facility and the existing ASR5 well.
