Pretreatment Program

The Pretreatment Program regulates the discharge of non-domestic wastes to the plant. This includes:
  • Catch basin contents
  • Groundwater
  • Industrial wastes and more
Regulations
Program personnel determine whether wastes will meet regulations. Where appropriate, waste sources are required to obtain either letters of permission or permits. In order to attain regulations, the sources may be required to control pollutant levels in the waste prior to discharge (pretreatment).
