When a heavy storm surcharges the combined sewer or a private line clogs, water can back up through a basement floor drain or toilet. That is Category 3 black water: it carries bacteria and contaminants and is not something to clean up with a mop and a bucket. The crews contain it, remove it, disinfect the space, and safely dispose of what it ruined.
Why sewage backs up in La Grange
- Combined storm-and-sanitary sewers surcharge in a hard rain and reverse into the lowest drain
- Tree roots and grease clog an old private lateral
- A failed or missing backflow preventer lets the main push water back in
- A collapsed or bellied clay line in a century-old neighborhood
Unlike a clean basement flood, black water requires protective gear, containment, and disinfection, and porous materials it touched usually have to go.
The sewage cleanup process
- Contain the area and set up the protective gear and negative air
- Extract the black water and remove contaminated carpet, pad, and drywall
- Clean and disinfect every hard surface the water reached
- Dry the structure to a verified reading and deodorize, the structural drying standard
the CDC's flood-water safety guidance explains why sewage-contaminated water is a health hazard, and the containment and cleaning follow the IICRC S500 standard for Category 3 water.

- Do not walk through it or try to clean it yourself
- Keep children and pets well away from the affected area
- Stop running water and using drains that feed the backup
- Turn off HVAC that pulls air from the contaminated space
A backflow preventer stops the next one
Many La Grange-area basement backups are the combined sewer pushing back in during a storm. An overhead sewer or a backflow preventer is the permanent fix, and it is worth asking about once the current cleanup is done and dry.
