Sewer Line Repair in Detroit, MI
Detroit's combined sewers backed up into thousands of basements in the 2014 and 2021 storms. If your basement floods through the floor drain in heavy rain, the public sewer is overloaded and a backwater valve is the usual protection. The Detroit Water and Sewerage Department has run a program installing them in eligible neighborhoods.

What is different about sewer line repair in Detroit?
Check that program before paying for flood protection yourself. The Basement Backup Protection Program has covered backwater valves and sump pumps for eligible homeowners in the areas hit hardest, with an inspection of the lateral first. Eligibility is by neighborhood and has changed over time.
Your own lateral is the other half. Clay pipe from the 1920s to the 1950s cracks, shifts and fills with roots, and a backwater valve cannot be installed on a line that is already failing. A camera inspection shows its condition. Backups that happen in dry weather are a lateral problem, not a storm problem.

Sewer Line Repair questions from Detroit
Will a backwater valve stop my Detroit basement from flooding?
It stops sewage backing up from the public sewer through your drains. It does not stop groundwater seepage or water entering through walls and windows, and the house cannot drain while it is closed.
Can I file a claim with the city after a sewer backup?
Michigan law sets a short deadline for notifying a public agency in writing after a sewage backup event. Contact the Detroit Water and Sewerage Department promptly for the claim process, and document the damage.
