How the crew handles sewage in Pasadena
Call and dispatch
A real person answers 24/7 and the nearest Pasadena crew rolls with pumps, air movers, and moisture meters.
On-site assessment
The crew traces the source and the full reach of the water, including what soaked into subfloor, plaster, and wall cavities.
Extract and dry
The extraction crew pulls the standing water, then runs air movers and dehumidifiers to the IICRC S500 standard, not just the surface.
Verify and document
The drying team logs moisture readings until the structure reads truly dry, then documents the loss for your insurance claim.
A sewage backup is never just water on the floor. Raw sewage is Category 3 black water, carrying bacteria, viruses, and human waste, so it needs a trained crew in protective gear, not a mop and a bucket. SOS Restoration answers live around the clock and reaches most of Pasadena day or night to pump it out, disinfect, and make your home safe again.
What Category 3 black water means
Restoration crews sort water into three categories, and sewage is Category 3, the most dangerous, often called black water. It carries raw human waste, bacteria such as E. coli, viruses, and parasites, and the category decides what can be saved and what has to go.
- Porous materials the sewage soaked, drywall, carpet, pad, and insulation, cannot be disinfected and are cut out and thrown away.
- Hard, non-porous surfaces like tile, concrete, and sealed masonry are cleaned, disinfected, and saved.
- Bleach and a box fan cannot pull contaminated water out of a wall cavity or subfloor, so wiping the floor leaves the real problem in place.
The crew seals off the affected rooms so nothing spreads, then treats every surface the sewage reached, not just the puddle you can see. Ready.gov keeps clear safety guidance for contaminated floodwater that lines up with how crews work a Category 3 loss.
Why Pasadena homes back up
Most sewage jobs here are not a broken toilet, they are a backup driven by storm and by age, and older north-central Pasadena and the west San Gabriel Valley see it most.
- Storm surcharge. Heavy San Gabriel foothill runoff and winter atmospheric-river storms overwhelm the lines, and the system pushes waste back up the lowest opening in the house, often a garage or floor drain. Los Angeles County Public Works explains the local flood control and sewer context.
- Old cast-iron laterals. The cast-iron sewer laterals under Craftsman and older homes in Alhambra, San Gabriel, and the Rosemead edge corrode and draw tree roots, which clog and split the line.
- Low ground near the Arroyo. Properties that sit low near the Arroyo and its side channels are the first to take a backup when the storm system runs full.
The sewage cleanup process
With black water the order matters. Crews contain the area, then the water extraction and removal gear pulls the black water and solids, crews cut out and bag soaked drywall, carpet, and insulation, disinfect every surface the sewage touched with EPA registered antimicrobial products, and the structural drying crew dries the structure to a verified reading before the crew deodorizes so the smell is gone, not masked.

☎ Call (626) 314-6471The smell comes before the water
A sewer backup almost always announces itself. If you notice a sulfur or sewage odor near a floor drain, a gurgle in the toilet when you run the sink, or drains emptying slowly all at once, stop using water in the house and call before a small backup becomes a flooded garage. In an older Pasadena home the cause is often a root-invaded cast-iron lateral that has been narrowing for years.
Health risks and getting the smell out
Sewage is a genuine health hazard. Contact with black water or breathing its aerosols can cause stomach illness, skin and eye infections, and breathing problems, and the risk is higher for children, older adults, and anyone with a weak immune system. Keep people and pets out of the flooded area until it is decontaminated.
Once the space is extracted, disinfected, and dried, the risk drops away and the odor goes with it, because the smell lingers only when contaminated material stays behind. Sewage that soaked into framing can feed mold within a day or two, so if it has started the mold remediation crew treats it in the same visit. Standard homeowners policies often exclude sewer backup unless you carry a water backup rider, so check yours, and crews document everything with dated photos and moisture logs.

Common questions, answered
What should I do right after a sewage backup?
Keep people and pets away from the water, do not run any more water in the house, and shut off power to the affected area only if you can reach the panel safely. Do not try to clean sewage yourself. Call (626) 314-6471 and a decontamination crew heads your way.
Is Category 3 black water dangerous?
Yes. Black water carries bacteria, viruses, and parasites, and even breathing the aerosols can cause stomach illness, infections, and breathing problems. Children, older adults, and anyone with a weak immune system are most at risk, so stay out of the flooded area.
What causes sewer backups in Pasadena homes?
Usually a storm surcharge from heavy foothill runoff, a root-invaded or corroded cast-iron lateral under an older home, or a low spot near the Arroyo that takes water first. Many backups come up the lowest opening in the house, often a garage or floor drain.
Can heavy rain cause a backup?
Yes, and it is common here. Winter atmospheric-river storms and fast foothill runoff overwhelm the lines, and the system surcharges and pushes water back up through low drains, sometimes with no fault in your own plumbing.
What gets removed and thrown out?
Category 3 water cannot be disinfected out of porous materials, so soaked drywall, carpet, pad, insulation, particleboard, and cardboard are cut out and disposed of. Hard, non-porous surfaces like tile, concrete, and sealed masonry are cleaned, disinfected, and saved.
How do you get the smell out for good?
The smell lingers only when contaminated material stays behind, so crews remove every porous item the sewage soaked, disinfect the surfaces, dry the structure fully, then deodorize the space. Once the source is gone and the area is dry, the odor is gone with it, not just masked.
Does insurance cover sewage cleanup?
Standard homeowners policies often exclude sewer backup unless you carry a water or sewer backup rider, so check your policy. Crews document the loss with dated photos and moisture logs so your claim moves, and the loss is documented for your claim.
How fast can you respond?
The response team answers live around the clock and reaches most of Pasadena and the San Gabriel Valley day or night. Extraction and removal of contaminated materials usually happen the same day, with drying and deodorizing over the following days.
