Types of On-Site Sewage Management Systems

There are a number of different on-site sewage management systems available. Each user and site will have different factors which will determine the type of system most suitable for installation.

The type of system to be used will mostly be determined by the Site and Soil Assessment which is carried out prior to the application to Install an OSSM.

Septic Tank with on-site disposal in absorption trench or beds
Aerated Wastewater Treatment System (AWTS)
Wet Composting System - Worm Farm
Waterless Composting Systems
