## Why sewage costs more

Under the IICRC S500 standard, sewage is **Category 3 (black) water**: it carries bacteria, viruses, and other contaminants. That changes the job:

- **Removal, not drying**, of contaminated carpet, pad, drywall (cut above the wet line), insulation, and porous contents
- **Protective gear** for the crew and separation from the rest of the house
- **Cleaning and disinfection** of concrete, block, and framing
- **Disposal** of contaminated materials
- **Longer timelines.** Published Lansing timelines are 5–7 days, or 8–12 with a full biohazard protocol.

## What moves the number

1. **Finished vs. unfinished basement.** More material to remove means more cost.
2. **How far it wicked.** Drywall draws water upward. A backup that sat overnight is cut higher.
3. **Contents.** Sorting, photographing, and disposing of stored items adds labor.
4. **Depth and area.** A few inches around the drain costs far less than a whole flooded level.

## Why Lansing gets so many backups

Older parts of Lansing still run on a **combined sewer**, one pipe for sewage and storm water. In heavy rain it overloads, and water comes up through the lowest drain in the house. The city is separating the system under a roughly $250 million program running to 2035. Private causes, like tree roots or a collapsed lateral, also cause backups on any system.

## Who pays

- **Insurance:** only if you have a **water backup endorsement**. See [sewer backup insurance in Michigan](/guide/sewer-backup-endorsement-michigan/).
- **The city:** possibly, if the public sewer caused it. You must file written notice **within 45 days**. See [the 45-day rule](/guide/michigan-sewer-backup-claim-45-days/).
- **Prevention:** Lansing reimburses city property owners up to **$4,750** toward a backflow valve. See [the program](/guide/lansing-basement-backup-protection-program/).

## Keep the cost down

Photograph everything, stop using water in the house, and call for cleanup quickly. Every hour sewage sits, it wicks higher into walls and more has to be cut out.

## FAQ

**Why can't sewage-soaked drywall just be cleaned?**

Sewage soaks into porous materials, and disinfectants can't reliably reach it. The IICRC S500 standard treats porous materials contaminated by Category 3 water as unsalvageable.

**Is a small toilet overflow priced the same?**

A toilet overflow contained to a tiled bathroom floor and cleaned quickly is a much smaller job. Once sewage reaches carpet, drywall, or the floor below, it's priced like any Category 3 job.

**Who pays for a sewer backup cleanup?**

Your insurer, if you have a water backup endorsement; possibly the city, if the public sewer caused it and you file written notice within 45 days; otherwise, you.
