Detroit Free Press staff Published 3:17 PM EDT May 17, 2019 The city of Northville is under a boil water alert until at least Sunday evening after a contractor hit a water line early Friday not far from the city’s water tower, officials said. The incident happened at about 8:15 a.m. at 8 Mile Road and Center. Soon after, officials said, water customers experienced low pressure. Tap water must be boiled for at least five minutes to kill any bacteria, officials said. The boil water alert may even last into Monday as the city awaits an all-clear on tests for bacteria. If residents or business owners have questions, they are asked to call the city at 248-349-1300 during office hours of 8 a.m. to 4:30 p.m. After hours, there will be a special recorded line at that same number with any important updates at ext. 2710.
