Sewage backup cleanup in Wichita
Sewage coming up a floor drain or toilet is Category 3 water. Stop using water, keep everyone out of the room, and expect anything soft it touched to be thrown out rather than dried.
Referral service, not a contractor. A callback request is passed to an independent local restoration company. We do not perform the extraction, drying or repairs ourselves.
What "Category 3" means in plain English
The term comes from the restoration industry's own standard.
Restoration companies grade water by how dirty it is, using the ANSI/IICRC S500 standard. In a February 2026 position statement, the S500 committee quoted the standard's definition: Category 3 water is "grossly contaminated" and can carry pathogens, toxins or other harmful agents that can make people seriously ill if they touch or swallow it.
The examples it lists start with sewage. They also include backflow from a waste line that comes from beyond any trap, "regardless of visible content or color." Put simply, water that pushed back up out of the drain line counts as sewage even if it looks clear. Rising water from rivers and creeks is on the same list, which is why the storm and flood damage page treats creek water the same way.
The statement also says rain blown in through a damaged roof is not automatically Category 3. The restorer inspects, asks where the water came from, and then decides.
The first hour of a sewer backup
Sewage in the house
In this order- Right away
Turn off every drain in the house
No flushing, showers, laundry or dishwasher, upstairs or down. Whatever goes into a blocked line looks for the floor drain on the way out.
- Next
Close the door on the room
The CDC says to keep children and pets away from the affected area until cleanup is complete. Stay out of any wet area with outlets or cords near the water.
- Then
Have the public main checked
Inside Wichita, call the City's sewer stoppage line at (316) 262-6000 during its weekday hours. Other towns have their own numbers.
- Before cleanup
Photograph the damage
Shoot the drain, the high-water mark and every damaged item before anything goes to the curb.
- Cleanup
Gear up or leave it to a crew
CDC lists rubber boots, rubber gloves and goggles when sewage is involved. EPA adds an N-95 respirator.
The City's main and your own line
Every house connects to the public sewer main through its own private pipe, usually called the lateral or building sewer. A blockage in the main is the city's to clear. A blockage in your lateral is usually a job for a plumber you hire.
This site could not find a page where the City of Wichita spells out exactly where its part ends or who pays for what, so ask when you call (316) 262-6000. Nearby Augusta does publish its rule. Its wastewater staff say the lateral, from just inside the basement out to the main, belongs to the homeowner, and that most backups they see start there, often from tree roots. Park City's sewer department makes the same point and adds that old clay and Orangeburg pipe let roots in more easily. The Augusta page lists that city's warning signs of a blocked main: sewage coming in while nobody is running water, neighbors on the same side of the street with the same problem, or water coming out of a sewer manhole.
What usually goes, and what gets cleaned
Sewage cleanup leans hard toward removal. HomeGuide's restoration guide says anything black water touches, including drywall, flooring, furniture and clothing, must be removed and replaced. CDC's cleanup guidance says to throw away anything that cannot be cleaned or dried quickly.
- Usually removed: carpet and pad, the lower part of wet drywall and the insulation behind it, upholstered furniture, mattresses, cardboard boxes and cloth items.
- Usually cleaned: concrete floors, tile and other hard surfaces, which are washed and then disinfected.
- Then dried: the framing and slab, with air movers and dehumidifiers, until moisture readings come back to normal.
The water extraction page covers the equipment side of a first visit.
What it tends to cost
Black water sits at the high end of every national price table. HomeGuide puts Category 3 removal and drying at $9 to $12 per square foot, and HomeAdvisor gives $7 to $7.50 for black water removal before repairs. HomeAdvisor also says removing two feet of sewage backup runs $2,800 or more.
Those are national figures, not Wichita quotes, and the rebuild is usually a separate bill. The water damage cost guide has the full tables and explains how to compare two written estimates.
Protecting the people in the house
From CDC and EPA cleanup guidance.
The CDC's floodwater safety page warns that contaminated water can cause wound infections, skin rashes, stomach illness and tetanus. Its cleanup guidelines add a few habits worth following even if a company does the heavy work:
- Wash with soap and water as soon as you finish, and wash any cut or sore that touched the water.
- Wash clothes worn during cleanup in hot water and detergent, apart from other laundry.
- Never mix bleach with ammonia or any other cleaner.
The EPA's disaster cleanup guide says people with asthma or a weakened immune system should stay away from the work, and children should not take part. If the basement still smells musty after it is supposedly dry, the EPA's 24 to 48 hour drying window has likely been missed, and a mold assessment is a separate specialist job.
Insurance: ask about the rider
The Kansas Insurance Department lists severe back-up due to flooding and sump pump failure among things not every homeowners policy pays for. Derby's floodplain office adds that flood insurance is not the answer to sewer backup, and suggests asking about a sewer backup rider on a homeowners policy.
Only your policy and your agent can say what applies to your house. This line does not handle claims or give coverage opinions. For questions or disputes, the Department's consumer line is 785-296-3071.
Keeping the next one out
Derby's floodplain page recommends having a plumber install backflow valves or plugs so water cannot push up through floor drains, and the Derby page covers the rest of that city's flood-proofing list. Augusta recommends a backflow preventer on the sewer lateral. A plumber can also camera your lateral and tell you whether roots are the problem.
For a basement that floods from more than one direction, the basement flooding page sorts out sump, seepage and drain water.
Sewer backup questions
What does "Category 3" water mean?
It is the dirtiest of the three water categories in the IICRC S500 restoration standard. The standard calls it grossly contaminated water that can carry pathogens or toxins. Sewage, waste-line backflow from beyond a trap and rising river or creek water are its main examples. A restorer decides the category after inspecting, and it changes the scope of work toward removal.
Can carpet be saved after a sewage backup?
Generally no. HomeGuide says materials black water touches, flooring included, must be removed and replaced, and CDC lists rugs among items to throw away when they cannot be disinfected. A small hard-surface rug might be cleaned, but wall-to-wall carpet and pad soaked by sewage are normally cut out. Ask the technician to note each removed item in the written scope.
Is a sewer backup rider the same as flood insurance?
No, they are separate products. Derby's floodplain office says flood insurance is not the answer for sewer backup and points homeowners to a sewer backup rider on the homeowners policy instead. The Kansas Insurance Department notes that not every policy pays for back-up. What your own policy includes is a question for your agent.
