Cause of break in Rockville water main still unknown
Crews still working to repair second break; no cost estimate yet for either repair
Rockville Public Works crews are still working to repair a second break in the city's water main two days after it occurred.
The 24-inch pipe the city's main distribution line that draws water from the Potomac River to serve Rockville residents broke around 4 p.m. Monday in the 10800 block of South Glen Road in Potomac, one block away from where the pipe broke for the first time July 7 at South Glen Road and Deep Glen Drive.
City spokeswoman Marylou Berg said crews continue to work around the clock to fix the pipe. She said crews worked through the heavy rain on Tuesday.
City officials still have not determined the cause of the break or how long it will take to fix it.
No water restrictions are in place this time. Mandatory restrictions on unnecessary use, such as watering lawns and washing cars, were in place after the pipe broke the first time.
Rockville received supplemental water from the Washington Suburban Sanitary Commission during the first break and is receiving some water from WSSC this time, Berg said.
Rockville customers are not without water. The city serves 13,445 homes.
Some residents in the city, including those in the King Farm, College Gardens and Plymouth Woods communities, as well as portions of other neighborhoods, get water from WSSC, which lifted restrictions for its users the day before the Rockville water main broke after a 96-inch water main, also in Potomac at Tuckerman Lane and Gainsborough Road, was found to be failing July 1.
At Monday's City Council meeting, City Manager Scott Ullery said Rockville would assess the cause of the breaks.
Berg said on Tuesday there was no cost estimate yet for either of the breaks to the water main, but the major expenses will include crew overtime and the cost of time and materials for the contractor called in to help repair the line.
