Dry Cleaners
All new dry cleaners and existing dry cleaners that change dry cleaning solvent must receive SacSewer approval to discharge separator wastewater to the public sewer.
The table below outlines what dry cleaning wastes and wastewater can and cannot be discharged to the sewer.
For the purposes of this information, a “drain” is defined as any floor drain, toilet, sink or washing machine.

- Separator waste only if characterized by the facility as non-hazardous through a hazardous waste determination (22CCR 66261.11) and approved by SacSewer
- Wet-cleaning wastewater
- Washing machine/laundry wastewater
- Air compressor wastewater
- Boiler blowdown
- Non-contact cooling water
DOES NOT Go Down the Drain

- Any separator wastewater that has not been characterized as non-hazardous and has not been approved by SacSewer
- Spotting table waste or wastewater
- Still residue/muck
- Tonsil or similar filter aid

Floor Drains
Floor drains must be protected from chemical leaks and spills. Options for spill protection include installing coated berms around drains, using spill trays to contain potential chemical spills, plugging the drain, or storing chemicals in a room without a floor drain.
