Water service was restored Tuesday afternoon to most Woodlawn residents and the offices of the U.S. Centers for Medicare and Medicaid Services in Baltimore County, a utility official said.

A water main break Monday left the federal workplace without water, and the repair caused a water cutoff to nearby residents.

Kurt Kocher, a spokesman for the city public works department, said that by midafternoon crews repaired a 7-foot section of the water main on Rolling Road. He said the broken section was embedded in rock, a factor that added to the repair time.

The repair work, which began Monday, also caused loss of water service to hundreds of residents in the Woodlawn and Windsor Mill areas and closed the road entirely between Security Boulevard and Fairbrook Road.

About 3,000 workers were notified that their offices would be closed all day Tuesday to give crews time to repair a 16-inch water main, which split Monday night, forcing water service in the area to be shut off.

According to an email message sent to the centers' employees around 10:15 a.m., agency officials said they expect the offices to open Wednesday.

According to a spokeswoman, some employees may have been able to work from home during the closure. In addition, the offices at 7210 Ambassador Road were not affected by the shutdown because that building did not lose water service, according to the agency.

Water will flow at low pressure levels for a few hours, Kocher said, but by Tuesday evening pressure should return to normal.

Kocher said the break on Rolling Road is the largest of several that crews have been working on Tuesday. Others include a water main break in the 500 block of S. Rolling Road, which has been fixed; and a water main break in the 7200 block of Pinecrest Road. Both of those are 8-inch water mains, he said.
