July 5, 2010, 12 a.m. - To ensure continued water supply for all WSSC customers and for fire protection and hospital/medical uses, Washington Suburban Sanitary Commission (WSSC) General Manager Jerry N. Johnson today called for mandatory water restrictions for all WSSC customers.  The goal is to reduce water usage by about one-third.  The restrictions take effect immediately and are expected to last at least four days.

The mandatory restrictions are necessary after monitoring technology indicated a failing section of a 96-inch water main located near the corner of Tuckerman Lane and Gainsborough Road in Potomac in Montgomery County.  “This technology, an acoustic fiber optic monitoring system, detected the problem, allowing us to take preventative measures now,” says Johnson.  “This proves the system works and helped us to prevent what could have been a much more serious situation. “  The fiber optics system was installed in the pipe three years ago and will eventually be installed in all of WSSC’s large water mains.  The process to repair the pipe has already begun and will continue around-the-clock until complete. Until that time it is imperative that customers:

 

Stop all outside water use – no watering lawns, no washing cars, no topping off swimming pools

Use water only as necessary

Limit flushing toilets (do not flush after every use)

Limit using washing machines and dishwashers (wash full loads only)

 

WSSC has been working with fire departments from both counties to make sure there is adequate fire protection, especially considering that this weekend is the 4^th of July and there will likely be numerous fireworks displays.  “We know this is a burden, especially on this holiday weekend.  But if everyone can be vigilant and cut their water use by a third, we’ll be ok,” said Johnson.  "We appreciate everyone's understanding, patience and cooperation while we work through this."

 

WSSC will notify customers once repairs are complete and mandatory restrictions are no longer necessary.
