Aquifer Storage and Recovery (ASR)

Project Description

In coordination with the Department of Ecology, the City partnered in a pilot project which consisted of drilling a deep bed well into the aquifer to be utilized much like a large storage reservoir. During the summer months water is pumped from the large storage reservoir (the aquifer) and during the winter months the same quantity of water, plus 5% more, is injected back into the aquifer to recharge it.  

Important Dates

None at this time.

Status

The City is currently conducting the sixth year of cycle testing to ensure all Ecology and Department of Health water quality parameters continue to be met. The City also is working with the Department of Ecology to issue a permanent reservoir permit, which would allow for continued permanent operations.
