54” Transmission Main Isolated in Chevy Chase

Resident Reports Leak – WSSC Takes Action

| News Release



Laurel – March 26, 2013: WSSC has discovered a leak in a portion of a 54" transmission main in a wooded area near the 32-hundred block of Coquelin Terrace in Chevy Chase after a resident reported seeing water on the ground yesterday afternoon.

After an inspector confirmed the leak, WSSC crews isolated a portion of the pipeline and shut it down Monday night. Water is now being drained from the pipe and an emergency contractor will begin repairs as soon as possible. No customers are without water, and there is no need for any water use restrictions.

This pipe is connected to the 60" main that failed last Monday night near Connecticut Ave. and Chevy Chase Lake Drive.

The 54" main does have acoustic fiber optic (AFO) monitoring installed, but the AFO did not signal problems with the pipe. AFO picks up wires that have snapped within PCCP pipe to warn of potential breaks in the pipe. It does not pick up leaks. This does not necessarily indicate any problem with AFO. It is much too early to determine the cause of the leak.

We thank the resident who called in the leak. We often receive help from the public in reporting small leaks or leaks in out of the way places.

We hope to have additional information late this morning.
