Homes in Yonkers and Mount Vernon have water again after unexpectedly losing service Wednesday morning.

People living in East Yonkers, North Yonkers and Mount Vernon had little or no water for about an hour and a half after New York City's Department of Environmental Protection turned off a 48-inch valve near the Kensico Dam to do maintenance work.

Yonkers Public Works Commissioner Tom Meier says he was not notified that the valve would be shut off, nor was his counterpart in Mount Vernon. He says precautionary measures would have been taken if they had known.

There wasn't any water at Mount Vernon Fire Department headquarters for a time, but there was still enough pressure in the hydrants to put out a small house fire.

Health officials say those who lost water should run the faucets for a while until the water looks clear.
