City of Colton Municipal Water Company and CDCFAQ
-
What causes spots on dishes?
Spots result from minerals in the water that remain after evaporation. Using a dishwasher rinse agent can help reduce or eliminate these spots. -
Why does my water appear milky or cloudy?
Typically, air trapped in the water creates this cloudy appearance. If you let the water sit, the air will dissipate and the water will clear. If cloudiness persists, please contact us for investigation. -
Is fluoride added to the water supply?
No, we do not add fluoride to our municipal water. -
Is the water chlorinated?
Generally not. Chlorine is only added following water line breaks to ensure safety after repairs. Additionally, we conduct an annual preventative chlorination with minimal levels. Any chlorine taste or odor typically disappears within a couple of days. -
Are there summer watering restrictions?
No regular restrictions exist. In rare instances involving well or pump issues, we may request conservation measures and reduced outdoor watering. In such cases, residents receive written notification. -
How much water equals one cubic foot?
One cubic foot of water equals 7.48 gallons. -
Why is there sand or sediment in my water?
Sand or sediment may enter the system from well operations or during water line repairs. We conduct regular flushing to remove these particles and improve water quality by increasing system flow. -
What can I do about low water pressure or sediment in one sink?
If issues affect only one sink, try removing and cleaning the faucet aerator, which commonly becomes clogged over time.
