Flushing of the Water Mains

Domestic water distribution flushing will start January 24, 2022

The Stanford Water Resources and Civil Infrastructure Department will flush the Stanford water distribution system during the estimated time period of January 24, 2022 through March 31, 2022. All flushing will take place on weekdays between 6 am and 4 pm.

This flushing program is a standard maintenance operation for water departments (typically conducted annually).  A filtration and pump system will be utilized to minimize the water sent to the drainage system during the maintenance.

Flushing the mains may cause some slight but temporary reduction in water pressure and possible water discoloration.  However, your water remains safe for drinking.  If you observe sediment or coloration in water, continue to run the water until it is again clear.
