Municipal sewer main backup
During heavy rain, overloaded city lines can push sewage back into basements through floor drains.
Category 3 Water · 24/7 · Kansas City Metro
A sewer backup is a health hazard, not an ordinary water leak. Dry Out Pros removes contaminated water, removes affected porous materials, cleans and treats surfaces, and dries the structure using IICRC Category 3 procedures.

Sewage Backup Cleanup
Sewage is Category 3 water, the most contaminated classification under the IICRC S500 standard. It can carry bacteria, viruses, and other pathogens. That changes what can be saved, what protective equipment is required, and how the affected area must be cleaned before drying begins.
Keep children and pets away from the affected area, avoid walking through it, and do not run fans that could spread contaminants into the rest of the house. Then call us. We set up containment, remove the water and affected materials, and clean and treat the area before drying.
Call 1-888-379-6880 or (816) 379-6887. We answer 24 hours a day, including nights, weekends, and holidays.
What we see most
During heavy rain, overloaded city lines can push sewage back into basements through floor drains.
Tree roots, grease, and collapsed pipes in the line to the street cause recurring backups.
Overflows that contain waste are treated as contaminated water, even when they look clear.
Basement bathrooms and laundry rooms rely on pumps that can fail during outages.
Basement floor drains are often the first place a sewer problem shows up.
Restaurants, multi-family buildings, and offices can affect several units at once.

Moisture readings map the affected area and find hidden water.
Standing water comes out and wet materials are evaluated for drying or removal.
Air movers and dehumidifiers run while readings are taken every day.
Photos, readings, and scope notes are organized for you and your insurance carrier.
Questions people actually ask
We do not recommend it. Sewage can contain harmful pathogens, and porous materials it touches generally cannot be cleaned and saved. Professional cleanup uses protective equipment, containment, and proper disposal.
Many standard homeowners policies exclude sewer and drain backup unless you added a specific endorsement. Check your policy for water backup coverage. We document the source and scope so your adjuster has what is needed to evaluate the claim.
Under IICRC guidance, porous materials that sewage contacted, such as carpet, pad, upholstered items, and the lower portion of drywall, are generally removed. Hard, non-porous items can often be cleaned and kept.
Often, yes, if the affected area can be contained and you have working plumbing elsewhere. We will advise you based on the extent of the backup and who lives in the home.
