A water main break early Sunday morning shut off water for about 12 hours to neighborhoods off of Route 40 near Lewis Lane in Havre de Grace.
The city's public works department reported that the break in a 12-inch main was caused by reconstruction work the city recently started on Lewis Lane between Route 40 and the CSX crossing.
"All the digging, excavation and vibrating of the base material was too much and apparently it just cracked," Larry Parks, the city's public works director, said Monday.
He said the water main cracked sometime late Saturday night or early Sunday morning and took 12 hours, into Sunday afternoon, to repair.
He is not sure how many people were affected, but said neighborhoods like Greenway Farms and the Woods of Bayview did not have water, as well as part of Route 40, starting at Otsego Street.
He also said the break would have probably affected every business along Route 40 from Otsego Street to as far as Desserts by Rita's.
The areas immediately around the site of the break had some flooding, he said.
Parks said he did hear some complaints about the break, but expected the issue to be fixed.
"We do have some valves that we have to replace that we found out as a result of it," he said.
After the new valves are installed, he said residents would not lose water if such a break were to happen again, he said.
The last incident he recalled of a water main break being caused by construction happened about five years ago, Parks said.
Parks did not know how much the repair work will cost the city as the new valves have not even been ordered yet.
Construction has not been delayed and there was minimal effect on the schedule, Parks said.
"We had to put some extra gravel in the area of the leak," he said.
The construction work on Lewis Lane is expected to take about 7 1/2 weeks.
