Sewage backup cleanup in Detroit, MI
Sewage cleanup treats the water as Category 3 (grossly contaminated): crews in protective gear remove it, discard porous materials it touched, clean and disinfect hard surfaces, and dry the structure. Don't try to clean sewage with household products and a mop.

Sewage backup cleanup in Detroit: local conditions
In June 2021, intense rain overwhelmed the sewer system in Detroit and nearby suburbs, sending water and sewage into tens of thousands of basements. Older neighborhoods are served by combined sewers, and many homes have original clay sewer laterals that crack, sag and fill with tree roots.
Because almost every Detroit home has a basement, and many are finished or used for laundry and storage, a backup quickly damages drywall, carpet, appliances and stored belongings. Sewage cleanup requires protective gear, removal of porous materials, disinfection and thorough drying.
After cleanup, a backwater valve, repairs to the sewer lateral, and a sump pump with battery backup reduce the chance of a repeat.

Sewage backup cleanup questions
Who is responsible for sewer backups in Detroit?
The homeowner is usually responsible for the private sewer lateral from the house to the main. Insurance coverage depends on having a sewer backup endorsement.
Can I clean sewage out of my Detroit basement myself?
It isn't recommended. Sewage contains bacteria and viruses, and porous materials it touched usually need to be removed and the area disinfected by trained crews.
Does homeowners insurance cover sewage backup?
Often only with a water or sewer backup endorsement, which most insurers offer as an add-on. Check your declarations page.
Is sewage cleanup dangerous?
Yes. Sewage contains bacteria, viruses and parasites. Professional crews use protective equipment and disinfectants for this reason.
