Service Authority’s Routine Spring Flushing Begins This Week

Beginning this week and continuing through mid-June, the Prince William County Service Authority will be conducting its annual spring flushing of the water distribution system. This is a routine maintenance process and is NOT related to the coronavirus pandemic.

Each spring, the Service Authority’s drinking water providers—Fairfax Water and the City of Manassas—temporarily change the primary disinfectant in their water treatment process from chloramines to free chlorine. Our water providers indicate that this temporary change facilitates an effective flushing program for the distribution system and is a drinking water industry best practice.

As part of this annual maintenance program, the Service Authority will be flushing its water mains by opening some fire hydrants and allowing them to flow freely for a short period of time. Customers might notice the following during spring flushing:

  • Service Authority personnel and trucks performing hydrant flushing activities in their neighborhoods.
  • A slight chlorine smell in their tap water. We suggest that customers refrigerate tap water or use water filters to reduce chlorine odor.
  • Brief periods of cloudiness in their tap water. The Service Authority recommends running the cold-water tap for approximately two minutes to reduce cloudiness.
