Floor Cleaning Wash Water
Remember most exterior drains and some interior drains are not connected to a sanitary sewer system, but instead are storm drains that lead directly to a ditch, stream, or lake. Discharging dirty wash water into one of these drains could pollute surface or ground water.
- Do dispose of wash water into the sanitary sewer.
- Do use a nontoxic floor cleaner.
- Don’t allow floor cleaning wastewater to go into a drain (inside or outside) or septic tank leading to a ditch, stream, or lake.
