CUSTOMER ALERT: Water Storage Exercise in Southern Prince George's County is Over

Low Pressure Was Not Detected During Exercise

| News Release



Customers with Discolored Water Should Follow Flushing Guidelines

Laurel, Md. – February 13, 2019 – WSSC’s water storage exercise in areas around Accokeek, Clinton and Brandywine in southern Prince George’s County is over. The exercise began at 8 a.m. on Tuesday, February 12, and ended at 10 a.m. today.

While it was possible that customers in the green area of this map could have experienced low water pressure during the exercise, WSSC water quality experts monitored the water supply and pressure throughout the exercise and determined there was no reduction in pressure. The water always met Safe Drinking Water Act standards and continues to do so.

While it is unlikely customers in this area will experience discolored water now that the exercise is over, please follow these guidelines if discolored water is present.

  • Run all COLD water taps for about five minutes or until the water runs clear.
  • Begin with the lowest faucet in your home or business and then open the other faucets one at a time, moving from your lowest floor to your highest. 
  • Once the water runs clear, usually in five minutes or less, turn off your faucets in the same order, lowest to highest.
  • You should also flush your refrigerator's water lines. 

If discolored water persists after running your COLD water lines for five minutes, please call WSSC’s 24-hour Emergency Call Center at 301-206-4002 or

WSSC conducted the water storage exercise in advance of future work to connect two large water mains together. The connection of these mains, which is part of the Maryland Department of Transportation State Highway Administration’s MD 4 at Suitland Parkway Interchange Project, will require WSSC to temporarily limit the flow of water into this area to safely allow this work to be completed. Data collected during the exercise will now allow WSSC to determine how long water in nearby storage tanks will be able to provide the necessary flow to meet demand while the water mains are out of service to safely make this connection. No date has been set for the water main connection project. WSSC will alert customers living in this area prior to the actual work taking place.

WSSC thanks its customers for their understanding during this important water storage exercise.
