TRENTON — A water main break is having an effect on two Mercer County communities.

Michael Walker, spokesman for Trenton Mayor Eric Jackson, told New Jersey 101.5 the break is in a 24-inch water line that burst around 12:30 a.m. in the East Ward. It sent water into the streets in roughly a four-block area around Walnut between South Olden and Garfield avenues.

Walker said crews have to wait for the water to fully recede so they can have access to the break itself.

The pipe is a feeder line that carries water to Trenton Water Works customer in Hamilton.

"It's a large water main made of galvanized metal and they're quite old," and they are vulnerable to changes in the temperature.

"One of our tanks in the Whitehorse-Mercerville area has been impacted. We are still trying to assess the impact that the break has had on water supply to parts of the Hamilton area," Walker said, adding that some customers are only experiencing low water pressure and brown colored water.

He said officials are not requesting that residents boil water before use, but residents should do so anyway if they’re concerned.

Hamilton Police said they have received calls from Trenton Water Works customers about low pressure and some brown colored water.
