Yes, if the public sewer caused the backup. Under Michigan's MCL 691.1416–.1419, you must give the responsible city or utility written notice within 45 days of discovering the damage, including your name, address, phone, the property address, the discovery date, and a brief description. Miss the deadline and the claim is usually barred.

[Water Damage Lansing](/) is a water damage restoration company serving Lansing, MI and the Greater Lansing area, and the Michigan sewer backup claim against the city is the one deadline we see homeowners miss most. It is set by state law, it is short, and almost nobody hears about it until it has passed.

## What the law says

Michigan's governmental immunity act generally protects cities from lawsuits, but [MCL 691.1416 through 691.1419](https://www.legislature.mi.gov/Laws/MCL?objectName=MCL-691-1416), passed as Public Act 222 of 2001, carve out an exception for a **"sewage disposal system event"**. That means a backup or overflow caused by a defect in a public sewer system. If the public system caused sewage or storm water to come into your property, you may be able to recover the damage from the governmental agency that owns or operates that part of the system.

There are conditions. The system has to have had a defect, the agency has to have known or reasonably should have known about it, and it has to have failed to take reasonable steps to fix it. The law also has a firm notice requirement.

## The 45-day written notice

Under [MCL 691.1419](https://www.legislature.mi.gov/Laws/MCL?objectName=MCL-691-1419), you must notify the governmental agency **in writing within 45 days** after the damage was discovered, or should have been discovered with reasonable diligence. The notice must include:

- Your **name, address, and telephone number**
- The **address of the affected property**
- The **date you discovered** the damage
- A **brief description of the claim**

The agency may inspect the property. If you contact the agency within the 45 days and it fails to give you written information about the notice requirements, a late or incomplete notice may not bar your claim. That's a narrow exception, though, not a plan. Treat 45 days as a hard deadline.

## Who to send it to in the Lansing area

The notice goes to the agency that owns or operates the part of the sewer that failed. Usually that's your city or township:

- **City of Lansing:** the Public Service Department runs the sewer system. Its number for the Basement Backup Protection Program is (517) 483-4456. Ask the city in writing where claims must be sent.
- **City of East Lansing:** the city publishes its own procedure. Written claims go to the Finance Department at 410 Abbot Road, East Lansing, MI 48823.
- **Townships (Meridian, Delhi, Delta, and others):** contact the township's public works or clerk's office and ask where a sewage disposal system event claim must be filed.

If you're unsure who owns the sewer, notify every agency that might and keep copies.

## How to document a backup for a claim

The city will look at whether its system caused the backup. Your evidence should show when, where, and how much:

1. **Photograph before cleanup:** the floor drain, the water line on walls, standing water depth, and damaged items.
2. **Note the time and weather.** Heavy-rain backups across a neighborhood point to the public system.
3. **Ask neighbors** whether they had backups the same night. Several on one street is strong evidence.
4. **Keep receipts:** cleanup, replaced items, and plumber reports. A plumber's camera inspection showing your lateral was clear helps show the problem was downstream.
5. **Keep removed materials documented.** Photograph carpet, drywall, and contents before disposal.

We photograph and log everything as we clean up a sewage backup, so you can attach it to the notice.

## Insurance is a separate claim

A claim against the city doesn't replace your insurance. A standard Michigan homeowners policy excludes sewer and drain backups unless you bought a **water backup endorsement**; see [sewer backup insurance coverage in Michigan](/guide/sewer-backup-endorsement-michigan/). If you have the endorsement, file with your insurer too. Your insurer may pursue the city itself.

## After the cleanup: preventing the next one

Lansing property owners can get up to **$4,750** back toward a backflow valve installed by a licensed plumber through the city's [Basement Backup Protection Program](/guide/lansing-basement-backup-protection-program/). If you've had one backup, a backwater valve is the single most effective fix.

## FAQ

**Does the 45 days start when the backup happened or when I found it?**

When the damage was discovered, or when you reasonably should have discovered it. If you were away and found the basement a week later, the clock generally starts at discovery — but don't count on an argument about it. File as soon as you can.

**Do I need a lawyer to file the notice?**

No. The notice is a short written statement with the items the statute lists. The city must tell you in writing where to send it and what it needs if you ask. Some owners consult a lawyer if the claim is denied or large.

**Will the city pay if tree roots in my line caused it?**

Generally no. The law covers backups caused by a defect in the public sewage disposal system. A blockage in your private service lateral — roots, grease, a collapsed pipe on your side — is your responsibility.
