Main Cleaning Program

From time to time, you may notice CCWD crews opening valves or fire hydrants and running water in your neighborhood.

Although it may appear to be wasteful, flushing of hydrants is an important maintenance practice for our water system and allows us to deliver the highest quality water to our customers. Flushing removes mineral and sediment deposits that build up over time in our underground system of pipes. While the buildup is not harmful to customers, it can create taste and odor issues if not flushed out.

The District uses best management practices to ensure its activities are safe for the environment and uses water quality indicators to determine exactly how much flushing is required so it doesn't flush more than what is required.

For questions or assistance, contact the CCWD Water Quality Hotline at 925-688-8156 or send an email.
