Industrial Waste Pretreatment

industrial waste/pretreatment processesThe Industrial Waste Section regulates industrial users of the sanitary sewer system in accordance with the Clean Water Act. County businesses are surveyed, inspected and monitored to prevent toxic or harmful substances from entering the collection system and reaching the treatment plant.

  • Reduction of pollutants to, and protection of treatment plants;
  • Lower treatment and disposal costs;
  • Improve health and safety;
  • Compliance with federal, state and local environmental regulations;
  • Cleaner environment.
