Sewage cleanup is the removal of waste water that came up through a drain or a line, or that a flood carried over a floor. It is treated as a health hazard, not as ordinary water. In Asheville, flood water over lower floors can carry sewage, so the crew sets up the protection, removes what cannot be cleaned and dries the rest on a record.
Sewage is different from clean water, and the difference changes everything about how the room is handled. Anything that touched it is treated as contaminated, the people in the room need protective equipment, and porous materials that soaked it are generally removed rather than cleaned. If you can smell it, see grey water in a drain or find a toilet or floor drain that is backing up, leave the area and make the call.
A backup from a drain can come from a blocked main, a full septic line or a sewer that has been overwhelmed by rain. A flood can carry sewage over a floor from outside. The cause matters for the claim and for the fix, so the crew records what it saw at the drain and at the low point of the room.
Do not enter sewage-contaminated water without protective gear, and do not work in it barefoot or with cuts on your hands. Keep children and pets out of the area. Ventilate the room without creating a draft through the affected area. If you feel unwell after exposure, see a doctor and mention the contamination.
The area is closed off and crew members wear gloves, eye protection, masks and boots. Children, pets and anyone with a weakened immune system are kept away until the area is cleared.
The crew checks the drain, the cleanout and the line that is backing up. Where a backwater valve exists, it is checked for function. The cause is recorded for the repair and the claim.
Standing sewage is extracted, and porous material that it soaked is removed, including carpet pad, some drywall, insulation and any soft goods that cannot be disinfected.
Hard surfaces and salvageable structure are cleaned with products suited to sewage, then disinfected and allowed to dry. Fixtures and drains are checked before they are used again.
The area is dried to readings, and the final log is kept. The homeowner is told which items were removed and why, so nothing is discarded without a reason.
Because it carries bacteria, viruses and other contaminants that a clean-water loss does not. The material it touches is contaminated, the people who handle it need protection and the drying can only start once the contaminated material is out.
A clean-water loss from a supply line can often be dried in place. Sewage cannot be dried in place, because the contamination stays in the material after the water evaporates. Carpet pad, porous insulation, soft goods and some drywall are usually removed and replaced, and hard surfaces are cleaned and disinfected.
The handling is also different for the crew. Gloves, eye protection, masks and boots are standard, and the area is ventilated and kept closed while the work is done. Nobody should try to clean up sewage without that protection.
For a very small amount on a hard floor, with protective gear and good ventilation, some people do. For anything that has reached porous material, a wall, a subfloor or a room used by children, it is a job for a crew. Do not mix cleaning products, and do not use a household vacuum on the water.
Bleach and ammonia-based cleaners should not be mixed, because the combination releases harmful gas. A household vacuum can spread contamination through its exhaust and can short out on wet floors. Use gloves, eye protection and a mask, and keep the room ventilated.
The bigger risk is what you cannot see. Sewage that soaked into the wall or under the floor keeps the contamination and the moisture in place, and it can cause illness long after the water is gone.
It means the drain or the line that serves it has a blockage or a failure somewhere, and the blockage needs to be cleared by a plumber before the house is used normally again. The restoration crew deals with the water and the damage. The line is a separate repair.
A backup can come from a blockage in the house's own line, from the public sewer or from the septic system if the house has one. The plumber will want to know where the water first appeared, which fixtures were in use, and whether it has happened before.
Where a backwater valve is fitted, its condition should be checked after any backup. A valve that is stuck open or closed will not do its job, and it is one of the few devices that can stop sewage from coming back into a lower floor.
Many standard homeowner policies exclude sewer and drain backup unless a separate endorsement was added, and flood water from a river is generally excluded from the standard policy as well. Check your policy and ask the insurer in writing what it covers, and keep the photographs and records.
A backup that comes from a river flood is treated differently from one that comes from the house's own drain, and the policy language decides which one applies. Keep a note of where the water came from and when, because the insurer will ask.
The North Carolina Department of Insurance accepts complaints about how a claim is handled. It does not decide the claim itself, so the written record and the policy wording matter most.
Clothing, bedding and soft furnishings that were in sewage are generally bagged, labelled and removed rather than washed at home. Hard items can be cleaned and disinfected, and the decision for each item is recorded.
Washing contaminated clothing in a household machine can spread the contamination to the machine and the drain. Put the items in sealed bags, label them with the room they came from and hand them to the crew. The bags are removed and disposed of in a way that keeps the contamination out of the home.
Keep one item of each kind in a photograph before it is bagged. The record helps when the claim is assessed, and it shows the insurer what was removed and why.
Sewage that comes up through a floor drain or a low fixture on a lower floor. The water is often in a basement, utility room or the lowest corner of the house.
Waste water carried over a floor by river or storm water. It mixes with silt and can spread to rooms the flood did not reach directly, so the scope covers the whole path.
A toilet, shower or sink that overflowed into the floor or the subfloor. The volume is often smaller, but the contamination reaches the materials under the floor, and those must be checked.
River and storm flooding can push sewage up through drains and across lower floors at the same time, so a single loss can have two sources. The crew checks for both before choosing the removal plan.
Heavy rain drives sewer backups in many older systems, because storm water and sewage share some lines. The rains that follow a river crest or a tropical remnant are the ones that most often cause the backup.
Houses on slopes sometimes have their lowest drain in the crawl space or the lowest utility room. Those are the first places the backup appears, and they are often the last places a homeowner looks.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

A water damage claim is generally decided on three questions: what caused the water, whether the policy covers that cause, and how much of the damage the evidence supports.
Yes. Sewage is a health risk, and the area should be closed off until a crew has cleared it. Calls are answered 24/7, and the crew is sent as soon as one is free.
Usually not. Carpet pad and carpet that have been in contact with sewage are generally removed, because the contamination cannot be fully taken out of porous material. The scope will say what is being removed.
The restoration crew deals with the water and the damage. A licensed plumber repairs or clears the drain and the line, and the two jobs are recorded separately.
The crew cleans and disinfects the affected area according to the material. If you have a specific concern about health, speak to a doctor, and ask the crew what products were used.
Ask a plumber to check the drain, the cleanout and any backwater valve. Keep drains clear, and avoid flushing or pouring anything that can block the line during heavy rain.
Items that were in sewage are assessed one by one. Hard items can often be cleaned and disinfected, and soft or porous items usually cannot be made safe and are removed after photographs are taken.
