A large water line break that was depleting Pittsfield’s water supply was fixed a little after 9 p.m. Saturday.

Residents had been advised Saturday to conserve water. Town Manager Kathy Ruth said that because of conservation efforts, water remained available while water district officials mended the break.

“These efforts kept enough water available for use so that the system did not have to be shut off,” she said in an email.

The leak was discovered early Saturday at a discontinued mill property on Greely Street after water department officials learned town water was losing pressure.

A valve was installed at the mill property and the water was turned off, fixing the leak and allowing the water district tanks to accumulate water again, Ruth said. She said there is enough water in the tanks for regular use by residents.

The Pittsfield Water Department operates 29.2 miles of water mains with 1,254 service connections, producing about 405,000 gallons of water per day, according to the town website.
