Sewage backups and drain overflows in Naoma are among the most hazardous water damage events a property can experience. Category 3 black water — raw sewage, backed-up drain lines, toilet overflows — carries bacteria, viruses, and pathogens at concentrations that make any contact a serious health risk. COS Water Damage Restoration's Naoma sewage cleanup team is trained, equipped, and certified under IICRC S520 protocols for Category 3 biohazard remediation — from containment through full restoration.
📞 Call +1-844-499-0972 — Naoma Sewage ResponseThe four factors that make our Naoma Sewage Cleanup service different from a general water damage company handling a sewage call.
COS Water Damage Restoration's Naoma sewage cleanup crew operates under IICRC S520 standard — the industry's governing protocol for Category 3 contaminated water remediation. This covers the specific containment requirements, the PPE standards that protect our crew from pathogen exposure, the material removal requirements (what can be safely dried versus what must be removed and disposed of as a regulated waste stream), and the multi-application antimicrobial sanitization protocol that must be completed before any structural drying begins.
Sewage-contaminated materials removed from Naoma properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Naoma crew bags, labels, and disposes of all contaminated material to applicable WV regulatory requirements. No dumping in standard refuse. No leaving contaminated materials in dumpsters that aren't rated for biohazard waste.
One application of sanitizer after a sewage event is not sufficient. Our protocol uses multiple applications with documented dwell times.
Our Naoma claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.
Here's what our certified Naoma Sewage Cleanup crew handles on every job.
Containment is established before extraction begins. This is non-negotiable on every Naoma sewage job.
No material gets dried in place unless it passes decontamination protocol first.
Sanitization happens before drying equipment is staged. This sequence matters.
Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.
Most WV homeowner's policies cover sewage backup events under a backup coverage rider. Our Naoma claim coordinators are familiar with the specific documentation that backup claims require — including the distinction between backup events (covered) and sewer line failures (may require separate coverage) — and build your claim file from the first day to match what your carrier's adjuster will look for. We file the claim, coordinate the adjuster visit, and follow the settlement through. You focus on your household; we handle the insurance.
One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.


Sewage events require immediate evacuation of affected areas. Our dispatcher will confirm this on the call.
Containment before contact. Source identified and addressed before cleanup proceeds.
No extraction, no material removal before the written scope is reviewed and approved by you.
Extraction, material removal, multi-phase sanitization, structural drying, and reconstruction proceed under your approved scope. Daily progress updates keep you informed. Clearance testing is coordinated where required or requested. Final sign-off at a walkthrough with your project manager. Written satisfaction guarantee on every Naoma job.



"We have a young child and a dog and the moment the sewage smell hit I knew this was something I couldn't handle myself. COS Water Damage Restoration's Naoma team was there in under 60 minutes, contained the area so our family could stay in the upper floors, and handled every part of the cleanup in a way I trusted. The clearance testing they coordinated at the end gave me documented proof that the remediation was complete."
"Three years later, no odor, no mold, no recurring issues. COS Water Damage Restoration did the Naoma sewage cleanup right the first time. I'm telling every neighbor I know to call them first."

The insurance claim was settled without any dispute."
