⚠️ Sewage is a Category 3 biohazard — do not attempt cleanup yourself. Call (602) 228-9494 now.
Disaster Recovery Restoration provides emergency sewage cleanup across Tempe AZ 24/7. Our HAZWOPER-certified crews handle Category 3 black water safely — sewage extraction, contaminated material removal, antimicrobial treatment, and structural drying per IICRC S500 protocols.
Sewage Backup Is Not a Plumbing Problem.
It's a Biohazard.
The IICRC S500 standard classifies sewage as Category 3 — grossly contaminated water containing fecal bacteria, pathogens, and biological hazards. Once sewage contacts porous building materials (drywall, insulation, subfloor), those materials cannot be dried and retained. They must be removed.
From the older clay-sewered homes near Mill Avenue and ASU to the slab-on-grade builds in South Tempe and Warner Ranch, DRR follows IICRC protocol exactly — because the alternative is leaving a biohazard inside your walls. Every sewage loss is fully documented for your insurance carrier from the moment we arrive.
Cat 3 Protocol
Our Sewage Remediation Process
Emergency dispatch — 60-minute response
Sewage events cannot wait until morning. Tempe crews are dispatched 24/7 with a 60-minute target arrival, full Cat 3 extraction equipment, and HAZWOPER PPE.
Source identification & containment
We identify the source — sewer-line backup, main-line blockage on Tempe's older clay sewers, or monsoon surcharge — and confirm the plumber has stopped the flow before remediation begins.
Category 3 extraction
All sewage-contaminated water is extracted using enclosed-tank truck-mount systems. No open-air extraction that could aerosolize biological hazards inside your home.
Contaminated material removal
Per IICRC S500, all porous materials that contacted Cat 3 water — drywall, insulation, flooring, carpet, subflooring — are removed and disposed of properly. No exceptions.
Anti-microbial treatment & drying
EPA-registered antimicrobials are applied to all affected structural materials. Structural drying begins immediately and continues until clearance moisture readings are achieved.
Documentation & clearance
Complete drying logs, photo documentation, and a final clearance survey for your insurance carrier. Every reading documented, every decision defensible.

FAQ
Sewage cleanup Tempe — FAQ
Is sewage backup covered by homeowners insurance?
Standard HO-3 homeowners policies do NOT automatically cover sewage backup — it is typically excluded from base coverage. However, many carriers offer a 'water backup and sump overflow' endorsement (rider) that specifically covers sewer and drain backup. Check your declarations page for this endorsement. DRR documents losses to IICRC standards so your claim is defensible regardless of which endorsement applies.
Why is sewage backup classified as Category 3 water damage?
The IICRC S500 standard classifies water by contamination level. Category 3 — 'black water' — is grossly contaminated water that poses a significant health hazard. Sewage contains fecal bacteria (E. coli, Salmonella), hepatitis A, and other pathogens. All porous materials that contact Cat 3 water must be removed — there is no safe way to dry and keep saturated drywall, insulation, or carpet that has been in contact with sewage.
How fast does sewage damage become a biohazard?
Immediately. Sewage is a biohazard from the moment it enters the structure. Beyond the initial contamination, bacteria multiply rapidly in Tempe's intense summer heat — within hours, microbial colonies can establish in walls and slab-level subfloor assemblies. There is no safe 'wait and see' window for sewage losses. Call DRR the moment you discover the backup.
Do I need to call a plumber or a restoration company first?
Both — but coordinate carefully. The plumber must stop the source first. DRR cannot begin remediation while sewage is still actively entering. Call your plumber and call DRR simultaneously so we can stage equipment while the plumber resolves the blockage. Do not attempt to clean up sewage yourself — improper handling spreads contamination and creates health risk.
Can sewage-soaked flooring and drywall be saved?
No. Per IICRC S500 Category 3 protocol, all porous materials that contacted sewage water — carpet, pad, drywall, insulation — must be removed. This is not negotiable and not a cost-cutting measure. Attempting to dry porous materials that absorbed sewage leaves biological contamination inside the wall assembly. Tile and sealed concrete slab can sometimes be cleaned and retained after proper antimicrobial treatment.
How long does sewage cleanup take?
Extraction and material removal typically takes 1–2 days. Structural drying after material removal takes 3–5 additional days. Total project timeline from event to ready-for-reconstruction: 5–8 days for a typical residential bathroom backup. Larger losses or delayed response will take longer.
Do you respond to older homes near Mill Avenue and ASU in Tempe?
Yes. We respond across all of Tempe — Downtown and the Mill Avenue District, Maple-Ash, North and South Tempe, Warner Ranch, The Lakes, and the student-housing corridor around ASU and the University District. Tempe's mix of pre-1970 clay-sewered homes and newer slab construction means backups behave differently by neighborhood; our crews account for both and target a 60-minute arrival anywhere in the city.
Is mold a risk after a sewage backup?
Yes — and it develops faster than after a clean-water loss. Sewage introduces organic matter that accelerates mold colonization, and Tempe's heat speeds it further. DRR's antimicrobial treatment and rapid structural drying significantly reduce mold risk. If remediation was delayed more than 48 hours, we recommend a post-clearance mold assessment before reconstruction.
Sewage backup in your home?
Don't touch it. Call us.
Sewage is a biohazard. Every minute of exposure increases health risk and contamination depth. DRR deploys certified Cat 3 crews across Tempe — 24 hours a day, with a 60-minute response target.
