Water main flushing is the process of cleaning or “scouring” the interior of water distribution main pipes by sending a rapid flow of water through the main pipes.  The benefits of flushing include: reducing bacterial growth; identifying missing or broken valves; ensuring that fire hydrants are operational; dislodging and removing sediments and deposit build-up; and, reducing taste and odor problems.  If after flushing, your water is discolored, try running only the cold water at one faucet for about 5 minutes and you should see that the water becomes clear. (Note that running the hot water, rather than cold water, pulls from the hot water heater and may delay or cause the water to not run clear.)  If the water doesn’t clear up after 5 minutes, wait for a few hours and try running the cold water only again. If the water is still discolored, please contact us so we can investigate why the water continues to have discoloration. Even if you are in an apartment or don’t pay your water bill direct, it’s important to let us know.

ACWWA flushes the water mains approximately once per year, in the spring. Look for signs that flushing will occur at the entrances to your neighborhood. The schedule will be updated frequently.
 
Occasionally, weather may delay / hinder the flushing process and emergencies may arise where ACWWA’s staff is called away from flushing for a day or two. Please call the office at 303-790-4830 or check ACWWA’s web page for updates.
