(CNN) Officials in Fort Lauderdale, Florida, said a temporary fix has water running again after a main break left an estimated 220,000 customers without service Thursday.

Water was flowing below normal pressure and was expected to return to "near normal" sometime Thursday night, Mayor Dean Trantalis said in an evening news conference.

A subcontractor repairing electric lines Wednesday struck a pipe that supplies water to a treatment plant, cutting off the city's water supply. No major incidents were reported as a result of the outage, the mayor said.

A partial patch was placed on the hole, increasing water pressure, Trantalis said.

Those involved in the repairs are "confident" that the patch will provide "temporary relief" while crews work to redirect the water flow through a backup line and replace the broken pipe, he said.
