Pretreatment Program

Goals of the Pretreatment Program

  • Prevent the introduction of pollutants into the wastewater treatment plant that will interfere with treatment operations
  • Prevent the introduction of pollutants into those plants that will pass through the treatment process and be incompatible with the environment
  • Improve the feasibility of reclaiming the municipal and industrial wastewater, and biosolids (sludge) for land application
  • Provide for the fair and reasonably equitable distribution of all costs associated with operation of wastewater collection and treatment systems
