Urban Water Management Plan

Cross connection and backflow prevention program

The City of Roseville requires annual testing of backflow prevention devices installed on water service lines for commercial/domestic use, irrigation and fire sprinklers to eliminate actual or potential cross connections into the public water supply.


Folsom Lake
Folsom Reservoir is where we obtain water resources for our community. We convey water from the lake to our water treatment facility in Granite Bay.  From there, it's gravity fed to homes and businesses in Roseville.
