General Owner Maintenance of a Home Sewage Treatment Plant.

On-site systems generally operate more efficiently when the wastewater load is minimised and ‘shock loads’ are avoided. Heavy water use activities such as laundering and showering should be evenly spread over the day and week. Detergent that are low in sodium and phosphorus should be used.

  • Do not allow large volumes of bleaches, disinfectants, whiteners or spot removers to enter the system.
  • Do not allow large volumes of food and cooking oils to enter the system and do not install an in-sink macerator.
  • The in-line strainer must be cleaned every few months to prevent clogging, and serviced by the service provided at least once a year.
  • Quarterly servicing must include measurement of the sludge and scum levels, and a check of the outlet and inlet junctions for blockages.
  • The service provider must flush and maintain the irrigation system quarterly
  • Surface water diversion mounds and drains must be regularly maintained to prevent stormwater entering the irrigation area.
  • The grass must be regularly mowed and the clippings removed from the site to maintain the nutrient uptake rate within the irrigation area.
