How sewage backup cleanup is handled, step by step
- 1
Contain it
Sheeting seals off the area so contaminated air stays put.
- 2
Extract it
Contaminated water is pumped out in protective gear.
- 3
Remove it
Porous materials that touched sewage are cut out and bagged.
- 4
Treat it
Surfaces get antimicrobial treatment before drying equipment goes in.
Sewage is Category 3 water, which carries bacteria and has to be handled as hazardous. In Anacortes the city places the side sewer, including its connection to the main, in the homeowner's hands, so a backup starts with a question about where the blockage sits.
The city and the side sewer
A resident with a backup can ask the Streets and Utilities department to inspect and clean the city main beside the side sewer. If the main is clear, the blockage is in the side sewer. If it is not, the main is the cause. That answer matters for the cleanup and for who handles the repair.
- Main clear: the side sewer is the cause
- Main blocked: the city main is the cause
- Both cases still need the cleanup
Wet weather and overflows
The city has a combined sewer system with two overflow locations in its discharge permit. In wet weather, sanitary sewer overflows have happened when combined volumes exceed capacity. The city is building a pump station at its wastewater treatment plant, scheduled for May through November of 2026, to prevent such overflows.
None of that changes the cleanup. A backup into a home is handled the same way wherever it started.
What the cleanup involves
The area is sealed with sheeting, and technicians work in protective gear. Contaminated water is extracted, porous materials are cut out, and every surface is treated before drying starts. Related water work is covered in basement flooding cleanup and structural drying.

Sewage Backup Cleanup questions, answered
Who is responsible for a backup on the property?
According to the city, homeowners are responsible for the side sewer, including its connection to the main, so a plumber handles that repair.
How can the blockage be located?
The city's Streets and Utilities department can inspect and clean the city main next to the side sewer, which shows whether the blockage is in the main or the side sewer.
Can carpet touched by sewage be cleaned?
Porous materials that touched sewage are usually removed, because bacteria stay in pad, carpet and drywall that cannot be fully disinfected.
Is it safe to stay in the house?
Not in the affected area. Sewage carries bacteria, so the area is sealed and occupants stay out until cleanup and treatment are complete.
Will the pump station being built stop backups?
The city says it is meant to prevent sanitary sewer overflows. A blocked side sewer is a separate problem that the pump station does not address.
What does the claim need?
Photos, the water category, a list of removed materials and the daily readings document the work for the adjuster.
