Sewer Backup in Kansas City? Here’s Exactly What to Do
There’s nothing quite like walking into your basement and discovering water coming up through the floor drain. Or worse, realizing it’s sewage.
A sewer backup is one of those homeowner emergencies nobody wants to deal with, but knowing what to do in those first few minutes can make a big difference in protecting your home and preventing additional damage.
If you’re dealing with a sewer backup in Kansas City, here’s what to do, who to call, and what you absolutely should NOT do until the problem is fixed.
1. Stop Using Water Immediately
This is the big one!
If sewage is backing up into your basement, bathtub, shower, or floor drains, stop using all water in your home immediately.
That means:
- Do NOT flush toilets. Every flush sends more wastewater into your sewer line.
- Do NOT run the washing machine. Laundry uses a significant amount of water that could make the backup worse.
- Do NOT run the dishwasher. That water has to drain somewhere, too.
- Do NOT take showers or baths. Even a quick shower could add to the problem.
- Do NOT run sinks or faucets. Avoid washing dishes, brushing your teeth with running water, or anything else that sends water down a drain.
- Do NOT pour chemical drain cleaners down the drain. They typically won’t solve a main sewer line blockage and can create additional hazards.
Until a plumber or sewer professional confirms the blockage has been cleared, treat your home’s plumbing as temporarily out of service.
2. Call Kansas City 311 to Report the Sewer Backup
If your home is located within Kansas City, Missouri city limits, one of your first calls should be to 311.
Kansas City 311: 816-513-1313
Why call the city if the sewer backup is happening inside your house?
Because the problem might be coming from the city’s main sewer line rather than your home’s private sewer line.
When you report a sewer backup through 311, KC Water can investigate the public sewer main serving your property and clean it if necessary.
This is important because a backup caused by a public sewer main may require a different response than a blockage in your private sewer lateral.
When you call 311:
- Explain that sewage is backing up into your home.
- Provide your property address.
- Describe where the backup is occurring and when it started.
- Ask for a sewer backup service request.
- Save your service request number for future reference.
Kansas City homeowners are generally responsible for maintaining and repairing their private sewer lateral, although certain repairs within city rights-of-way or easements may qualify for city assistance under specific conditions.
Our advice: Report the problem to 311 and contact a plumber promptly. You don’t want to waste valuable time waiting to find out which part of the sewer system is causing the issue.
Important: Kansas City 311 applies to properties within KCMO city limits. If you’re in Parkville, Liberty, Gladstone, Overland Park, or another surrounding community, contact your local sewer utility or public works department instead.
3. Protect Your Belongings and Stay Away From Sewage
If wastewater is coming into your basement or another part of your home, your next priority is preventing additional damage while keeping everyone safe.
Here’s what to focus on:
- Keep people and pets away. Sewage can contain harmful bacteria, viruses, and other contaminants.
- Move valuables if it’s safe. Protect important documents, electronics, furniture, and sentimental items before the water reaches them.
- Avoid electrical hazards. If water is near outlets, appliances, or electrical equipment, stay out of the area. Never enter standing water to access your electrical panel.
- Keep contaminated items separate. Anything touched by sewage may require professional cleaning or disposal.
- Take photos and videos. Document the damage from a safe location before cleanup begins.
If sewage has already spread across your basement floor, avoid walking through it. A professional restoration company can help determine what needs to be cleaned, disinfected, or removed.
And remember, never risk your safety to save belongings.
4. Call a Kansas City Plumber
Once you’ve reported the issue to the city, it’s time to get a plumbing professional involved.
A plumber can evaluate your home’s sewer line, locate a blockage, and determine whether drain cleaning, sewer line camera inspection, or additional repairs may be necessary.

5. Document the Damage and Contact Your Insurance Company
Sewer backups can cause expensive damage, especially when finished basements, flooring, drywall, or personal belongings are involved.
Before you start throwing things away or scheduling major repairs, document what happened.
Take photos and videos of the affected areas, make a list of damaged belongings, and save invoices for plumbing, cleanup, and restoration services.
It’s also worth contacting your homeowners insurance company to find out whether your policy includes water backup or sewer backup coverage.
Standard homeowners insurance policies don’t always cover sewer backups automatically. Coverage may depend on whether you purchased an additional endorsement and the circumstances of the damage.
If you have coverage, ask your insurance company what documentation they need and whether there are any requirements for emergency mitigation.
6. Clean Up Safely After the Sewer Line Is Fixed
Once the blockage is cleared and your plumbing professional confirms that the system is working properly, you can begin addressing the cleanup.
If sewage entered your home, regular household cleaning may not be enough.
Depending on the extent of contamination, you may need professional water extraction, disinfection, drying equipment, and removal of damaged porous materials.
Carpet, padding, drywall, and insulation that have been contaminated by sewage may need to be removed.
Avoid running fans that could spread contaminants through the home before the affected area has been properly assessed.
If you’re dealing with significant damage, our Kansas City vendor resource page also includes local restoration companies that can help with water damage and cleanup.
7. How Can You Prevent Another Sewer Backup?
Once you’ve survived your first sewer backup, chances are you’ll want to do everything possible to avoid another one!
A few things Kansas City homeowners can consider:
- Schedule a sewer camera inspection. This can help identify tree roots, pipe damage, or recurring blockages.
- Keep grease out of drains. Cooking grease can build up inside sewer pipes over time.
- Only flush toilet paper and human waste. Even wipes labeled “flushable” can contribute to clogs.
- Consider a backwater valve. Ask a licensed plumber whether this type of device makes sense for your home.
- Address recurring drainage problems. Slow drains, gurgling toilets, and repeated backups deserve professional attention.
Older homes throughout the Kansas City metro may have aging sewer lines, making inspections and maintenance especially valuable.
