Pretreatment Program Rules, Regulations, and Policies




The purpose of MSD's Pretreatment Program is to:


  • Prevent the introduction of pollutants into our public sewer system that will pass through the system without being adequately treated into local rivers and streams.
  • Prevent the introduction of pollutants into our sewers and treatment plants that will interfere with our operations.
  • Protect MSD personnel in the course of their employment and the general public.
  • Enable MSD's compliance with its National Pollutant Discharge Elimination (NPDES) permits, sludge disposal, and other environmental regulations.
