A frozen pipe spilled hundreds of thousands of gallons of water in downtown Oak Creek on Monday morning.
Public Works Director Bob Redding said he suspects the leak was caused when a pipe supplying a water hydrant broke.
He said he got a call from the water plant manager telling him that water levels were dipping Monday morning at about 9 or 9:30. As he left the office to search the town for leaks, a resident walked in and told him about the spill at the corner of Arthur Avenue and Williams Street.
Workers dug through hard, frozen ground for about an hour before they could reach the valves and stop the water, Redding said. One house, which is vacant, remained without water Monday afternoon.
Public works crews were bringing in a pump to remove water that had seeped underneath one house, but otherwise there were no damages, Redding said. Workers will continue to work on the leak, but it could take as many as two days to fix, he said.
The line break is two blocks south of the water leak in late December that left a sheet of ice on the road.
