The Detroit Water and Sewerage Department serves more than just the City of Detroit.
It's water and sewer lines stretch beyond the city's boundaries and into the surrounding suburbs and communities.
Under the proposal, the city would retain ownership of the 1,075-square-mile system, but the 126 communities and 4 million people who use its water and sewage services would be represented by a regional authority that manages contracts, water rates and future projects.
Members of Detroit City Council are reportedly in Lansing today lobbying against the bill. Council President, Charles Pugh, is quoted as saying:
"We are willing to have a regional discussion, but when the discussion is over, Detroit will still own and control the system. We built out the system, and we have a right to maintain control of it. Anything less than that is illegal."
You can see how far Detroit's sewer and water lines stretch into outlying communities on the Detroit Water and Sewerage Department's page.
