Sewage backups and drain overflows in Tempe 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 Tempe sewage cleanup team is trained, equipped, and certified under IICRC S520 protocols for Category 3 biohazard remediation — from containment through full restoration.

Why Choose Us

What Sets COS Water Damage Restoration Apart for Sewage Cleanup in Tempe

The four factors that make our Tempe Sewage Cleanup service different from a general water damage company handling a sewage call.

☢

IICRC S520 Category 3

IICRC certification is the standard that defines whether a sewage cleanup was done correctly. Our Tempe team is certified. The difference is measurable.

🚫

Regulated Disposal

Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Tempe job.

💧

Hospital-Grade Sanitization

After contaminated material is removed and Category 3 extraction is complete, every structural surface that contacted sewage water receives multiple applications of EPA-registered, hospital-grade antimicrobial and antifungal treatments. The sanitization sequence — spray application, dwell time, surface wipe-down, second application — is protocol-driven, not judgment-call driven. Our Tempe crew follows the sequence on every surface, every time.

📋

Insurance & Air Quality Coordination

Sewage cleanup claims in Tempe typically proceed under homeowner's policy coverage for drain backup and water damage. Our Tempe coordinators are experienced with backup coverage riders and know how to document Category 3 events for claim approval. For commercial properties or clients requiring clearance testing, we coordinate third-party air quality and surface sampling after remediation to provide a written clearance certificate before reconstruction begins.

Services

Sewage Cleanup Services Our Tempe Team Performs

COS Water Damage Restoration handles the complete scope of Sewage Cleanup in Tempe — from containment and extraction through material removal, sanitization, structural drying, and rebuild. Category 3 protocols, start to finish.

☢

Containment Setup & Source Control

The first action our Tempe sewage crew takes on any Category 3 event is establishing negative-pressure containment — critical plastic sheeting barriers that prevent sewage contamination from spreading into unaffected areas of the property through airborne particles, foot traffic, and air circulation. Containment also controls odor migration within the property while remediation is underway. Simultaneously, we identify and coordinate the correction of the blockage or failure that caused the backup — whether that's a main line obstruction, a failed cleanout, or a sump failure — so that remediation isn't interrupted by a secondary event.

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a Tempe property requires specific PPE — full protective suits, respirators rated for biological hazard, and disposable boots — for every technician in the contamination zone. We use dedicated contaminated-water extraction equipment that is not shared with standard water damage jobs and is properly sanitized between uses. After extraction, all materials that contacted Category 3 water and cannot be decontaminated to a safe standard — carpet, pad, standard drywall, fiberglass insulation, and any non-cleanable surface materials — are removed as regulated waste, bagged in approved containers, and disposed of under AZ biohazard material regulations.

💧

Multi-Phase Antimicrobial Sanitization

After material removal, every remaining structural surface — framing, subfloor sheathing, masonry, concrete, and any hard surface that contacted sewage water in your Tempe property — receives a multi-phase sanitization treatment using EPA-registered, hospital-grade antimicrobial and antifungal agents. The sanitization sequence includes spray application, documented dwell time, surface contact, and at minimum one additional application after the first dwell cycle. This is not a one-spray process. The S520 protocol our Tempe team follows is designed to address the pathogen load that Category 3 water deposits on structural surfaces.

💨

Odor Neutralization & Air Treatment

Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.

📋

Insurance & Backup Coverage Claims

Most AZ homeowner's policies cover sewage backup events under a backup coverage rider. Our Tempe 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.

🏠

Post-Remediation Reconstruction

One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.

Our Process

How Sewage Cleanup Works in Tempe — Category 3 Protocol

Call — Biohazard Dispatch

Sewage events require immediate evacuation of affected areas. Our dispatcher will confirm this on the call.

Arrival — Containment First

Our Tempe crew arrives in full Category 3 PPE with containment materials, dedicated contaminated-water extraction equipment, and sanitization products. Containment is established before extraction begins — no exceptions. After containment, we identify the source of the backup and coordinate correction if needed before the cleanup scope is assessed.

Assessment & Written Scope

No extraction, no material removal before the written scope is reviewed and approved by you.

Remediation & Rebuild

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 Tempe job.

Reviews

Tempe Customers on Our Sewage Cleanup Service

★★★★★

"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 Tempe 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."

"The thing that stood out with COS Water Damage Restoration's Tempe sewage cleanup team was the containment setup — I've seen other companies skip it or do it loosely, and you can tell they don't understand why it matters. This team had proper negative-pressure containment up before they extracted a gallon of water. The two-phase sanitization after material removal, the hydroxyl generator running during drying, the final surface swab coordination — this was a Category 3 remediation done to the actual standard, not a watered-down version of it."

★★★★★

"I've used general contractors for water damage before with mixed results. After calling COS Water Damage Restoration for a sewage event in Tempe, I understand the difference between a certified Category 3 remediation team and a general restoration company that 'also does sewage.' The protocols aren't comparable."

FAQs

Common Questions — Sewage Cleanup in Tempe

Why is sewage water treated as a biohazard in Tempe properties?

Sewage water — including backed-up drain water, raw sewage, and toilet overflow contents — is classified as Category 3 under the IICRC S500 water damage standard. Category 3 water is defined as grossly contaminated and contains pathogenic bacteria, viruses, parasites, and other biological agents at levels that pose a direct health risk to humans and animals. Contact without appropriate PPE, breathing air in an uncontained Category 3 space, and exposure of household members to inadequately remediated surfaces are all real health risks. This is why proper containment, full PPE, and compliant sanitization are non-negotiable steps in Tempe sewage cleanup — not optional upgrades.

What materials are removed versus saved during Sewage Cleanup in Tempe?

Under IICRC S520 Category 3 protocol, porous materials that contacted sewage water and cannot be decontaminated to a safe standard are removed as regulated waste. In a typical Tempe sewage event, this includes: carpet and pad (always), standard wallboard drywall that was submerged or splashed, standard fiberglass or cellulose insulation, and any other porous finish material that absorbed Category 3 water. Hard, non-porous surfaces — concrete, ceramic tile, metal framing, pressure-treated lumber — can typically be decontaminated in place using the sanitization protocol. Our Tempe project manager evaluates each material individually and documents the removal decision in the written scope.

Does homeowner's insurance cover sewage backup in Tempe?

Coverage for sewage backup events in Tempe typically depends on whether your homeowner's policy includes a backup coverage rider. Standard homeowner's policies generally exclude sewer and drain backup damage unless this specific rider is included. Backup coverage riders are relatively inexpensive to add and cover most drain backup events. Our Tempe claim coordinators review your policy details and document your claim to match your specific coverage terms — including the important distinction between a backup event and a sewer line failure, which may be covered differently.

Is clearance testing required after Sewage Cleanup in Tempe?

Third-party clearance testing — air quality and surface swab sampling performed by an independent industrial hygienist — is not universally required after sewage cleanup in Tempe, but it is available and appropriate in several situations: commercial properties with regulatory requirements, rental properties where a landlord needs documented proof of remediation for tenants, situations where immunocompromised individuals occupy the property, or any case where a client wants independent verification beyond our own completion documentation. We coordinate third-party clearance testing on request and can schedule it immediately after the final sanitization cycle.

How long does Sewage Cleanup take in Tempe?

A typical Tempe sewage cleanup project runs: Day 1 for containment, extraction, and material removal; Days 1-2 for sanitization cycle (multiple applications with documented dwell times); Days 2-6 for structural drying under daily monitoring; clearance testing coordination if needed (24-48 hours for lab results); and then reconstruction, which ranges from a few days to several weeks depending on the scope of material removed. Your Tempe project manager provides a realistic timeline at the initial assessment and updates it as the drying program progresses.

Can I stay in my Tempe home during sewage cleanup?

Whether you can remain in your Tempe home during sewage cleanup depends on the contamination zone and the containment configuration our team establishes. For events confined to a basement or a single room where negative-pressure containment can isolate the remediation area from the occupied portions of the home, remaining in place is often feasible. For events that affect living areas, bedrooms, or the main floor, temporary relocation is strongly recommended during the active remediation phase — typically 1-3 days. Our Tempe project manager evaluates the specific situation and advises on habitability at the initial assessment.
