ASR

Some of the wells in the Sunrise Water system produce water of low quality. Rather than abandon the wells entirely and lose the capital investment in constructing them, we are investigating using the wells for aquifer storage and recovery, or ASR. 

In ASR, during periods of peak river flow, such as the fall and winter, water produced at water treatment plants is pumped into the ground to be stored until periods of high demand or drought during the summer. The water is then pumped back out of the aquifer for use. This approach allows the use of the naturally occurring aquifer as a storage facility, increasing the amount of treated water that we can store, without requiring the construction of additional reservoir capacity.  This approach is not useful in all areas and requires extensive testing prior to being permanently permitted by the State of Oregon.  Sunrise Water is in the testing phase of the permitting process.
