City main or owner lateral
The city maintains the sewer main, while property owners are responsible for their plumbing and for the sewer lateral all the way to the main. A backup that starts in the lateral is the owner's to fix, and one that starts in the main is a call to the city.
Two sewer providers
The City of San Leandro Water Pollution Control Division runs the Water Pollution Control Plant, which serves the northern two thirds of the city, and part of town is served by Oro Loma Sanitary District instead. Cleanup is the same either way, but the agency to notify about the main differs.
- Porous materials like carpet and pad are removed
- Hard surfaces are washed and treated
- Air scrubbers run until the area is closed out
Why sewage is different
Sewage carries bacteria and viruses, so it is never simply dried and left in place. Carpet, pad and wet drywall that touched it go out, and within a 24 to 48 hour window mold can follow on whatever stays damp. See the main sewage backup page or the San Leandro hub for more.

Is sewage backup an emergency?
Yes. Sewage is contaminated water, so exposure and spread are the concerns, and the sooner the area is contained the less material has to be removed.
Can I clean it up myself?
A small spill on a hard floor is manageable with protective gear, but carpet, drywall or a larger area calls for professional containment and treatment.
Who is responsible for the sewer lateral?
Property owners are responsible for their plumbing and the lateral all the way to the main, and the city maintains the main itself.
Does a San Leandro home sale require a lateral certificate?
Not currently. The city does not require a compliance certificate when homes are sold, though it may adopt a lateral ordinance later.
What causes a sewer to back up?
The city names grease, tree roots, broken pipes, missing cleanout caps and groundwater or rainwater entering the system as common causes.
Will insurance pay for sewage cleanup?
Many policies exclude backup unless a rider was added, so the policy language decides. Photos and itemized records help whatever the outcome.
Seal it off and clean it right
Tell the crew which fixtures backed up and which rooms are wet, and the plan covers containment, removal and drying.
