UPDATE: As of 7/28/2023, CFPUA has completed its annHydrant flushingual flushing program for the Sweeney-Richardson Water System.

Flushing is a routine maintenance operation conducted by thousands of water utilities every year. During this activity, water is forced through pipes at high velocity and systematically flushed out of the fire hydrants, removing accumulated sediment.


When will flushing be performed? 

To minimize customer impact, the program work is conducted during the overnight hours between 10:00 p.m. and 6:00 a.m. Monday nights through Friday mornings. 

Maps of areas to be flushed will be posted on this webpage each Monday throughout the flushing program. Scroll down to see the areas scheduled for flushing this week. 

Will my water service be impacted?

The flushing process does not impact the safety of drinking water, and CFPUA does not anticipate issuing boil water advisories as a result of the flushing program.

Because of the nature of the process, it is possible that customers may experience periods of low pressure and/or water discoloration while flushing is being conducted in their area. Customers who do experience discoloration are advised to run the cold water for at least one to three minutes to allow the lines to clear.

Why is CFPUA flushing this summer?

This is the first time since 2020 that CFPUA has conducted our regular flushing program. Resuming regular flushing will help ensure that sediment does not accumulate in parts of the water system.

Flushing occurs in the warmer months for two main reasons: 

1) Warmer weather can increase the possibility of issues related to disinfection byproducts, and;

2) Conditions are safer for our employees - and our customers - by eliminating the potential for nighttime freezing of roadways or sidewalks.
