Why backups happen on the plateau
The side sewer runs from the house to the public main. Tree roots from the firs, cedars and maples around many Sammamish homes work into joints in older side sewers, and grease and wipes build up behind them. Lower-level drains, basement toilets and showers are where the backup shows up first.
- Roots in the side sewer
- Grease and wipes in the pipe
- Overloaded lines in a heavy storm
- Septic systems on some larger rural lots
PPE and containment
The crew wears gloves, boots, eye protection and respirators at minimum. The area is sealed with plastic and run under negative air with HEPA air scrubbers so contaminated air does not spread. OSHA sets the worker protection rules for this kind of cleanup.
What gets removed and treated
Carpet, pad, drywall, insulation and anything porous above the water line is removed and bagged. Hard surfaces are cleaned and treated with an EPA-registered antimicrobial, left for the label's dwell time, then dried. The EPA indoor air quality pages explain why damp, contaminated materials affect the air in the whole house.
- Porous materials: removed, never dried
- Hard surfaces: cleaned, treated, dried
- Belongings: cleaned only if non-porous
Trade fact: Sewage backup is Category 3 from the first minute. Even a small backup on a basement floor gets containment and antimicrobial treatment.
