Asotin averages about 18 inches of rain a year. Backups here usually come from blockages, roots or broken pipes rather than storms, but the cleanup is the same. About 56% of homes in Asotin were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time.
The work often covers:
- Cleanup of sewage under a house or in a crawl space where pipes have failed
- Bagging and proper disposal of contaminated materials as hazardous waste
- Odor removal and deodorizing after the sewage has been taken out
- Septic tank and lift station overflow cleanup inside and around buildings
- Cleanup after toilet, tub, shower and floor drain overflows
How Sewage Cleanup Works in Asotin, WA
2. Sewage extraction
Standing sewage is pumped or scooped out, and the contaminated area is mapped to see how far the liquid traveled.
3. Removal of porous materials
Carpet, padding, drywall and insulation that soaked up sewage are cut out, bagged and hauled away as contaminated waste.
4. Disinfection and final check
Hard surfaces and framing are cleaned and disinfected, odor is treated, and the crew checks the area before it is cleared for use.

Raw Sewage Cleanup: Questions from Asotin, WA Property Owners
Why does drywall have to be removed after sewage?
Drywall is porous and holds contamination that can spread germs and odor long after the surface looks clean. Crews usually cut out wall board that sewage touched, and often take out a margin above the wet mark to reach clean material.
What if the sewage came from a septic tank?
A septic overflow is cleaned as raw sewage, both inside any affected building and on nearby ground. Contaminated soil, materials and surfaces are handled and disinfected. A septic service may also need to empty or repair the tank.
How do I get sewage smell out of a house?
The smell comes from the contamination, so the fix is removing sewage and soaked materials first, then disinfecting and deodorizing. Air fresheners only cover it. If the odor persists, hidden material such as subfloor or insulation may still hold sewage.
Can sewage backup make me sick even after it is cleaned up?
If the cleanup missed contaminated materials, germs and odor can linger. That is why crews remove porous materials, disinfect every surface they touched and inspect the work. Thorough removal is what lowers the risk.
Can a sewage cleanup service work at night or on weekends?
Yes. Sewage backups do not wait for business hours, so you can call Asotin Biohazard Cleanup Help any time, 24/7. Describe what happened and you get the next safe step explained.
How do I clean sewage off concrete?
Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
