In the days after a water main break in southwest Detroit flooded homes and forced residents out on rafts, Jackie Muscat thought something was a little fishy with what she was being asked to sign: a liability waiver that had to be completed if she wanted city-sent contractors to fix her home.

The affected area has just under 400 homes, and so far officials believe about 200 need to be restored, Duggan said. Officials from the city and the Great Lakes Water Authority have promised to pay for damages and restoration for what Duggan called the "failure" of the water system.
