Every year TUD publishes its an annual water quality report. The free report gives the results of the tests it does in order to make sure your water meets federal and state drinking water regulations. The report also explains where your water comes from and includes other useful information.
From the time your drinking water is purified at a treatment plant until it arrives at your tap, it may pick up things along the way that change the way it looks. Sometimes this happens as close as your home’s own plumbing.
Cloudy water: Water is cloudy when air gets in and makes tiny bubbles. The bubbles are harmless and will disappear if you let the water sit in a glass for a few minutes.
Dirty water: Usually when water looks dirty, it’s because of changes in the way that the water delivery system is being operated. When the direction that water flows in the pipe is changed — for maintenance work on a water main, when a fire hydrant is broken in a car accident, or there is a break in a water main — materials at the bottom of the pipes get stirred up. Usually, the water looks dirty for a short time and you shouldn’t drink it until it looks clear. One way to speed the dirty water out of your own pipes is to run cold water through all of your faucets for a few minutes. If the water is still not clear, then do the same thing again every half hour or so. The problem should go away within one to two hours. If it doesn’t, call TUD at (209) 532-5536.
Orange, red, brown or yellow water: Rust can turn water orange, red, brown or yellow. Rust gets into the water from two places — your water utility’s pipes or your own plumbing. To find out if the colored water is related to a plumbing problem on your property or your water heater, fill a large white bowl or bucket with water from the hose bib or faucet closest to the your water meter. Let the water run for two full minutes and then fill the bucket or bowl with water. If it is clear, then the problem is most likely related to the inside plumbing or water heater. If not, you should contact TUD at (209) 532-5536.
