WSSC Repairs, Advisories, Updates & Water Saving Tips

July 6 Update

WSSC Lifts Mandatory Water Restrictions

Effective Immediately

Section of 96-inch Pipe is Successfully Replaced

Customers Can Return to Normal Usage 

(Laurel, MD, July 6, 2010)  General Manager Jerry N. Johnson has announced the Washington Suburban Sanitary Commission (WSSC) is lifting the Mandatory Water Use Restrictions, effective immediately.  WSSC serves customers in Montgomery and Prince George’s counties.

"Our pipe is back in service.  I want to thank our customers who were unavoidably inconvenienced by these water restrictions,” said Johnson. “We made the right decision and took the proper precautions when we decided to immediately repair the pipe. The restrictions were unfortunate, but necessary.  We needed to be proactive to prevent what could have been a very serious situation."

WSSC [had] continued the restrictions into Tuesday to make certain that the water meets state water quality standards and ensure the health and safety of our customers.  WSSC has never had a drinking water violation in 92 years of operation.  Tests confirmed this morning that those standards have been met.  The pipe was put back in service and now the water use restrictions have been lifted. 

The [restriction] order was issued on Thursday July 1, 2010 after a state-of-the-art monitoring system detected a potential weakness in a section of a 96-inch pipe near the intersection of Tuckerman Lane and Gainsborough Road in Potomac in Montgomery County.  In order to maintain pressure for fighting fires and to reduce risk to the entire system, it was necessary to reduce water usage to take the pressure off of another, smaller transmission pipe.  A preliminary inspection of the pipe indicates obvious corrosion and damage. It will undergo a full forensic analysis.

WSSC asked for a 30 percent reduction in water use, with a prohibition on outdoor use.  This necessitated cooperation throughout the counties, the state and the region.  “I want to thank Governor Martin O’Malley, Montgomery County Executive Isiah Leggett and Prince George’s County Executive Jack Johnson, their staffs and emergency personnel; as well as WSSC’s Commissioners for their support of our actions,” stated General Manager Johnson. "I also want to thank the media who took extra steps to help inform the public; the State Highway Administration for its cooperation; our customers who cut back on water usage; the contractor who made the repairs; and of course the team at WSSC who literally worked around the clock to fix the pipe and to inform the public.  I know it was a major inconvenience, especially on a holiday weekend."

A sophisticated monitoring technology called Acoustic Fiber Optics (AFO) was installed in the 96-inch Pre-stressed Concrete Cylinder Pipe (PCCP) three years ago during a routine inspection. Wires are embedded inside the PCCP and covered by a layer of concrete.  When corrosion causes the concrete, and then the wires, to deteriorate, the wires snap and make a “ping” sound. AFO works by “listening” for those sounds. An alarm was sounded Thursday June 30, 2010 after eight pings were detected over a 24-hour period.  That set off a series of events which led to WSSC taking the pipe out of service and ordering the Mandatory Water Restrictions.

While work on the pipe is complete, work to restore the site will continue for several days.  WSSC wants to thank the residents and motorists in the area for their patience.
