On-site Sewage Management Systems (OSMS)

What is On-site Sewage Management?
On-site sewage management involves the treatment of wastewater, followed by the release of liquid (treated wastewater) and solid (sludge, septage and compost) products into the environment. If your house is not connected to the sewer, you probably have an on-site sewage management system (OSMS) to treat the wastewater from your household.

Types of OSMS
Types of on-site sewage management systems include, but are not limited to:
  • Septic tank and absorption trenches;
  • Septic tank and pump-out service;
  • Septic tank and spray irrigation;
  • Wet composting;
  • Waterless composting; and
  • Aerated wastewater treatment systems (AWTS) with subsurface irrigation.
NSW Health sets the standard for systems able to be installed to deal with single domestic wastewater management.
