Geren Island Water Treatment Plant
Geren Island, a small island just Southeast of Salem, Oregon, is home to the Geren Island Water Treatment Plant (GIWTF) that treats freshwater from the Santiam River. For more than 80 years, the GIWTF has been an efficient, reliable component of Salem’s potable water system. The slow sand filtration treatment process has effectively treated water from the North Santiam River; however, recent changes in the North Santiam Watershed have created significant challenges for the GIWTF. Improving the resiliency and treatment capability of the GIWTF was key to the project’s success.
