-
Discharge wastewater from cleaning equipment
into a sink, toilet, or other drain connected to the sanitary sewer system,
or pump wastewater to your truck for proper off-site disposal.
-
Never allow wastewater
to be discharged into a street, driveway gutter, parking lot or storm
drain.
-
Filter wastewater before discharging it
to the sanitary sewer to remove fibers and other debris could clog sanitary
sewer pipes.
-
Dispose of the filtered material in the
garbage if it is free of hazardous substances.
-
These guidelines apply even if the cleaning
products are labeled “nontoxic” or “biodegradable”. Such products
can still have harmful environmental effects if they enter the storm drain.
