The Great Lakes Water Authority also says it has removed water from the site of the water main break, and crews have excavated the area.

Per a release:

Based upon current conditions, it is anticipated that an approximately 12-foot section of pipe will need to be removed, and the replacement section of pipe has been ordered. The replacement pipe is expected to be delivered on-site within the next 24-hours.

FYI, The city of Detroit has set up a hotline at 313-774-5261. That's where impacted residents can go to get set up in hotels and other temporary services.
