Prince William Water flushes water from fire hydrants connected to its distribution system each spring in order to forcefully draw water through its network of pipes. This process dislodges sediments and minerals that may have collected in water mains since the prior year’s system flush.

Sometimes, the flushing process causes short-term cloudiness in water mains by stirring minerals and sediments. Please run cold water from your tap until the cloudiness goes away if you have this problem.

Please email customerservice@pwwater.org or call (703) 335-7950 to reach Prince William Water's customer service department if your water seems cloudy for an extended period of time.
