Water service was returned to most customers after a 12-inch main broke in the Perry Hall area Tuesday morning, according to the Baltimore Department of Public Works.
The break, which occurred Tuesday in the 4100 block of Joppa Road, had disrupted water service and closed the roadway between Seven Courts Drive and Belair Road, said Kurt Kocher, a city public works spokesman. On Wednesday morning, one lane in each direction was open to traffic.
The break also resulted in a water surge that forced the Cromwell pumping station to temporarily shut down, causing customers in the area bordered by Joppa Road to the north, Loch Raven Boulevard to the west, Belair Road to the east and Northern Parkway to the south to lose water entirely or experience low pressure or discolored water, Kocher said. Service to the majority of customers was restored, but 25 business located near the break were still without water as of Wednesday morning.
Tens of thousands of people in the area were affected, Kocher estimated. The vast majority of them had their water turned back on by Tuesday evening.
The issues began as crews were conducting ongoing work at the Towson Reservoir, near Burke Avenue and Hillen Road, and had to divert water, which affected pressure on nearby pipes, Kocher said.
"What we believe happened is a surge that did occur from those maneuvers probably broke this line at Joppa Road" and caused the Cromwell station to shut down, he said.
He said crews continued to work to repair the main, which broke in three places. Kocher did not have a definite timeline for when the connection would be fixed.
"I can't promise anything," he said. "Hopefully, if all goes well we can have everything in place today."
