System Information
System Description
New Kinmundy Reservoir, the primary source, pumps water directly to the treatment plant at up to 120 gpm. Old Kinmundy Reservoir and the Kinmundy Borrow Pit are used only during emergencies. Old Kinmundy Reservoir upstream is now used as a settling basin for New Kinmundy Reservoir. Forbes State Park uses up to 150,000 gallons per month during the summer.

Developments since 1989:
New Kinmundy Reservoir came online in 1998. Old Kinmundy Reservoir was lowered 4 feet for a wetlands program and now is used as a settling basin. Kinmundy Borrow Pit was taken offline in 2006. These latter two sources are still available during emergencies. The new lake's large storage capacity has allowed for summer bulk water sales at rates up to 0.05 mgd.
Note: *The loss of the Alma satellite (pop. ~350) has diminished recent production.
