Alameda County carries a Very High river flood risk rating from FEMA, and rising water can overload sewer pipes and push wastewater back up through floor drains. About 77% of homes in Oakland were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time.

A typical sewage & biohazard cleanup job includes:

  • Sanitizing after sewage reaches concrete slabs, tile grout and unfinished basement walls
  • Bagging and proper disposal of contaminated materials as hazardous waste
  • Disinfection of hard surfaces, framing and subfloors with EPA-registered products
  • Odor removal and deodorizing after the sewage has been taken out
  • Septic tank and lift station overflow cleanup inside and around buildings

How Sewage Cleanup Works in Merriwood, Oakland, CA

1. Walk through the damage

Technicians trace the sewage from the source to the farthest wet spot, including under cabinets and into wall bases.

2. Extract and clear

Sewage is removed from the floor and low areas, and debris, trash and soiled belongings are cleared out.

3. Removal of porous materials

Carpet, padding, drywall and insulation that soaked up sewage are cut out, bagged and hauled away as contaminated waste.

4. Treat and verify

Disinfectant is applied to every affected surface, the space is dried and aired out, and the crew inspects the finished work.

Sewage Cleanup Frequently Asked Questions in Merriwood, Oakland, CA

Is sewage cleanup the same as water damage restoration?

No. Water from a clean source can often be dried in place, but sewage is a biohazard that requires removal of contaminated materials and disinfection. Drying alone does not make a sewage-affected space safe.

What is Category 3 water, also called black water?

Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.

What are the signs of a sewage leak?

Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.

What if the sewage came from a septic tank?

A septic overflow is cleaned as raw sewage, both inside any affected building and on nearby ground. Contaminated soil, materials and surfaces are handled and disinfected. A septic service may also need to empty or repair the tank.

Should I call a plumber or a cleanup company first?

If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.

Can carpet be saved after a sewage backup?

Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.
