Pretreatment

Objective

By placing controls and/or limits on levels of certain pollutants in wastewater discharged to your sewer system, you:

  • Prevent interference with the operation of your wastewater treatment plant.
  • Prevent the introduction of pollutants that could pass through your wastewater treatment plant untreated and into the receiving body of water.
  • Improve opportunities for reuse or recycling of wastewater and sewage sludge.
  • Prevent the introduction of pollutants that could cause health or safety problems to the public or the environment.
