Residents in downtown St. Paul are being asked not to drink tap water after a 20-inch water main ruptured in Lowertown overnight.
KARE 11 reports the ban affects those from I-35E to Highway 52 and University Avenue to the bluff line (the area shaded in yellow).
Crews are working to repair the broken line Saturday after thousands of gallons of water rushed through the streets around 12:30 a.m.
The city is also conducting tests to make sure the water is safe to drink. Until then, residents should use bottled water as a precautionary measure until further notice.
The Pioneer Press reports residents and several bars and restaurants including Barrio and Mancini's Char House lost water service immediately after the rupture. Some bars were forced to close early.
St. Joseph's Hospital also reported their engineers were addressing water problems.
Rick Larkin, St. Paul's director of emergency management, tells the Associated Press that water pressure has been restored to most of the grid, but some are still without water.
At least eight to 10 square blocks were flooded, causing significant street damage.
The Pioneer Press says crews also responded to a related water main break at Western Avenue and Sturgis Street.
The cause is still unknown.
