E/One Grinder Pump Case Study: Big Lake, Skagit County, WA

E/One Grinder Pump Case Study: Big Lake, Skagit County, Washington
Replacing centrifugal pumps with E/One grinder pumps
Serving a population that grows by 25 percent every summer, Skagit County’s Sewer District operators wanted to ensure that Big Lake’s water quality, local wildlife and vacationers’ fun were protected - without blowing out the department’s operating budget. The original pressure sewer system was designed to use centrifugal pumps, which proved to be problematic: Level sensors failed repeatedly, the rail-mounted system would freeze, and pumps required recurring service calls and replacement. O&M costs were high.
