Sewage is not an ordinary leak. It carries bacteria and should never be handled with household tools. Anyone with a backup should keep children and pets out and avoid the affected room. Handling it with mops and household cleaners spreads contamination, and it leaves bacteria behind in carpet, baseboards and the lower part of walls.
How the city's system fits in
Gresham has a separate sanitary sewer, not a combined system. The city's Infiltration and Inflow Control Program targets cracks that let stormwater into the wastewater pipes, which adds flow in heavy rain. Repairs found in testing are scheduled from summer 2026. Those programs help the public system, but a backup inside a house is still treated as an emergency cleanup on the property.
Sewage in the house? Describe the room and how much water came up, and the crew plans the cleanup.
What cleanup involves
- Extraction of contaminated water
- Removal of carpet, pad and soft materials
- Cutting drywall above the wet mark
- Cleaning and sanitizing of hard surfaces
- Air scrubbing to reduce odors and airborne particles
Drying comes after cleaning
Equipment runs only once contaminated material is gone, so air is not moved across unclean surfaces and spread into other rooms. Moisture readings then confirm the structure is dry before repairs begin. For clean water issues, see water extraction. Crawl spaces need their own plan, covered under crawl space removal.

Sewage Backup Cleanup questions in Gresham, WA
Short answers about sewage backup cleanup, from the first hour to the last reading.
Is sewage water dangerous?
Yes. It can carry bacteria and viruses, so skin contact and breathing the vapors should be avoided until trained crews finish the removal and sanitizing.
Can carpet be saved after a backup?
Rarely. Carpet and pad that touched sewage are usually discarded, since they cannot be fully sanitized, and the same goes for soft furnishings.
Who handles the cleanup?
Plumbing after the meter is the homeowner's responsibility, according to the city. A plumber clears the blockage in the pipe, and a restoration crew handles the contamination and drying.
What causes a backup in heavy rain?
Cracks in sewer pipes let stormwater into the wastewater system, which adds flow in heavy rain. A blockage or a broken pipe in the home can also push water back up.
Will insurance cover a sewage backup?
Many policies need a water backup endorsement to pay for this kind of loss. Check the policy early, and keep photos, invoices and moisture readings for the adjuster.
