Heavy rain overwhelms sewer systems in Detroit and older suburbs, backing water into basements.
In Detroit: The June 2021 storms flooded tens of thousands of basements and freeways across the region. In Grand Rapids: The Grand River's record 2013 flood threatened downtown and flooded low-lying areas. In Lansing: The Grand and Red Cedar rivers flood low-lying areas during heavy rain and snowmelt. In Flint: Heavy rain and snowmelt flood older basements.
Basements are nearly universal. Older bungalows and colonials in Detroit, Grand Rapids and Lansing often have aging sewer laterals and drain tile.

Other risks in Michigan
Frozen pipes and ice dams
Long, cold winters freeze pipes, and heavy snow causes ice dams.
Storm and wind damage
Severe thunderstorms damage roofs and knock out power, which stops sump pumps.
Great Lakes shoreline erosion
High Great Lakes water levels in recent years eroded shorelines and damaged lakefront homes, and wave-driven water can reach foundations during storms.

Sewage & Biohazard Cleanup questions
How do I prevent sewer backup in a Michigan basement?
Install a backwater valve, keep floor drains clear, consider a sump with battery backup, and add a sewer backup endorsement to your insurance.
How do I verify a Michigan contractor?
Search the contractor's residential builder or maintenance and alteration license on LARA's license lookup.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
