A municipal water main break Monday night in an industrial area of north Minneapolis disrupted water flow Tuesday morning and prompted the city to issue an ongoing water boil advisory to affected residents and businesses.
The "significant water main break" occurred about 5:30 p.m. Monday in the 2900 block of 2nd Street N. City crews are still draining water from the cracked main and will begin repairing it soon, said Margaret Anderson Kelliher, the city's public works director.
"The water main that broke yesterday is a 36-inch cast iron pipe. That main has been serving the city since 1888," Kelliher said. "That can give way after all these years in service."
Water pressure fluctuations can cause minor weak spots in a pipe to break, she said, though the exact cause of this breakage isn't known. Cold weather can also contribute to the breaks.
Affected residents and businesses are on the east side of Interstate 94, she said, including 80 single-family or duplex residences and Lowry Towers, a public housing building.
Some customers on the 2nd Street North business corridor, from Dowling Avenue to 24th Avenue, were still without water Tuesday afternoon, city officials said.
The city said the boil-water advisory covers N. 3rd Street from Lowry Avenue south to 26th Avenue, and N. 4th Street from 29th Avenue south to 26th Avenue.
Customers in the affected area are asked to boil water for three minutes before using it for cooking or drinking. The advisory will remain in effect until the city determines the water is safe to drink without boiling it first.
