WATER MAIN FLUSHING FAQ

What is water main flushing?

Over time, natural sediments can accumulate in the large water pipes (called mains) located beneath the streets. While these sediments are safe, they may affect water color, taste, and odor. Water main flushing is cleaning the interior of water mains and removing any accumulated sediment by sending a rapid flow of water through the mains. 

Why is the City of Colton flushing the water mains?

Colton Public Works and Utility Services Department is committed to providing customers safe, reliable water. We take pride in consistently delivering water that meets and exceeds Federal and State water quality standards. We perform routine water main flushing to ensure our water maintains its high-quality long-term. 

Will I see an impact on my water service during the flushing?

No impacts on water services are expected during the flushing process, and water will remain safe to drink. However, you may experience some temporary discoloration or sediment in your water. If you notice any water quality issues, try running the water at an outside hose bib for several minutes to flush the line between your meter and the house. Inside your home or business, remove the aerators from your faucets, and then run the faucets for several minutes to keep from plugging water filters and toilets. We recommend monitoring water quality before starting laundry to avoid potential stains. I let my faucet run for a few minutes, but I’m still seeing discoloration.
