A sewage backup is never a mop-and-fan job. Under IICRC S500, sewage is Category 3 water the moment it enters the house, because it carries bacteria and viruses. Parts of north Everett still run on older combined sewer lines that carry both sewage and storm water, so a heavy rain can surcharge the system and push water up through the lowest drain in the house.
What causes backups in Everett homes
- Combined sewers surcharging in heavy rain in the older north end
- Roots and sags in old clay or cast-iron side sewers
- Grease and wipes blocking the main line
- A failed or missing backwater valve on a basement drain
The Category 3 protocol
The mitigation team sets containment and HEPA air scrubbers so contamination does not travel through the house. The extraction crew removes the sewage, and porous materials it touched, including carpet, pad, insulation and drywall above the water line, are removed and bagged. Hard surfaces are cleaned and an EPA-registered antimicrobial is applied for its full dwell time. Only then does the drying team set air movers and dehumidifiers. Floodwater follows the same rules on the storm and river flood page.

Answers
Sewage Backup Cleanup questions, answered
Can I clean up a small sewage backup myself?
A very small backup on tile can be cleaned with protection and disinfectant, but anything that reached carpet, drywall or a larger area should follow the Category 3 protocol.
Why does carpet have to go?
Porous materials soaked by Category 3 water cannot be reliably disinfected, so they are removed rather than dried.
Why does my basement drain back up when it rains?
In parts of north Everett, older combined sewers carry storm water and sewage together, and heavy rain can overload them so water rises to the lowest drain.
Is sewage backup covered by insurance?
Many homeowners policies need a separate sewer or water backup endorsement. Coverage depends on your policy, so it is worth checking with your own insurer.
Is it safe to stay in the house?
Usually, if the affected area is contained and people stay out of it. Those with health concerns may want to stay elsewhere during cleanup.
How long does sewage cleanup take?
Removal and disinfection often take a day or two, followed by several days of drying depending on the materials.
