Flushing Line Program

One way CVWD ensures high quality water to customers throughout the district is through the water mainline flushing program.

As part of the District Preventative Maintenance Program, CVWD field maintenance crews conduct their Flushing Program. The program involves flushing fire hydrants or water lines in cul-de-sac streets to remove stagnant water. Stagnant water may cause taste and odor problems which can make the water unpalatable to drink.

Service Area
The California Department of Public Health (CDPH) requires water purveyors to flush hydrants and dead end lines (in cul-de-sac streets) to remove stagnant water. This requirement ensures customers continue to receive high quality water every day.
