On-Site Sewer Management Systems (OSSM)

Last modified: November 10, 2009 - 5:30 PM

On-site Sewage Management System refers to all kinds of effluent management systems, including traditional septic tank and trench systems, pump-outs, composting toilets and Aerated Wastewater Treatment Systems (AWTS).

Basically if you live or rent a home that is not connected to the sewer you have some sort of On-Site Sewage Management System in your back yard.

The most common systems found within the Goulburn Mulwaree Council LGA are:

  • Septic Tank and Trench/Transpiration Bed Systems
  • Aerated Wastewater Treatment Systems (AWTS)
