      Wastewater discharges from premises vary, and as such, may require different treatment facilities to meet allowed wastewater discharge characteristics. These treatment facilities may include grease arrestors, oil separators, cooling pits, lint traps, dilution pits etc.

      Current maintenance and/or cleanout records are to be kept on-site for access by Hunter Water Corporation’s trade waste officers to confirm compliant operation, maintenance and cleanout frequency of pre-treatment facilities.
