Between mid-March and mid-June, Service Authority personnel and trucks will be working throughout our service area to complete the annual water system flushing. Crews will move from neighborhood to
neighborhood, opening fire hydrants in brief intervals to draw water forcefully through our network of pipes. This process will dislodge
sediments and minerals that may have collected during the past year.

Customers may experience a brief period of cloudiness in their water as sediments are agitated in the water pipes. If this occurs, run cold tap water for about two minutes until the cloudiness dissipates.

For updates about the specific locations and times where our crews are flushing, visit the Service Authority Facebook and Twitter pages.

YOU ASK, WE ANSWER

Why does the SA change its disinfection for
drinking water every year?

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.

What is the Service Authority’s recommended watering schedule?
Watering your lawn at a different time of day than your neighbors helps to stabilize water pressure in your community, so the Service Authority asks you to follow our lawn and landscape watering schedule below.

Please limit water and irrigation during the peak demand hours of 5 a.m. to 7 a.m.
The Service Authority encourages customers to stay alert for utility impostors and other suspicious activity affecting our water and wastewater infrastructure. Utility impostors falsely claim to be Service Authority employees and request access to homes or businesses to collect water samples or conduct other business.
You can protect yourself with the following information:

  • Our field employees always wear a Service Authority uniform and carry an ID badge.
  • All Service Authority vehicles display our logo.
  • Service Authority employees never initiate an in-home visit without a scheduled appointment and never conduct financial transactions or ask for personal information in the field.
Report Suspected Impostors

If you have concerns about whether a person at your door is a Service Authority employee, call our 24-hour Emergency Dispatcher at
(703) 335-7990 or the Prince William County Police Department non-emergency line at (703) 792-6500.

Report Other Suspicious Activity

If you notice other suspicious activity, such as tampering with manholes or water meters and opening fire hydrants or other valves without a permit, complete our online report at www.pwcsa.org/sar or call (703) 335-7990 if you believe it is a water emergency. 
Let’s find out! Try this activity to see how much water you use over two days. Put a check mark in the second column below each time you do a listed activity. Calculate how much water you use in two days by multiplying the number of checks in the second column by the number of gallons.
Does this amount surprise you? Can you think of any ways to use less water? Water is a limited resource so it is important to use it wisely.
