Onsite Effluent Disposal Assessment

Our Focus

Onsite Effluent Disposal Assessments to AS/NZS1547

Onsite effluent disposal assessments evaluate the suitability of a site for the disposal of sewage and other forms of effluent. In Australia, the standard for onsite effluent disposal assessments is AS/NZS1547, which provides guidance on how to determine the suitability of a site for effluent disposal and how to design and construct an onsite effluent disposal system.

The assessment process typically includes collecting information on the soil and water characteristics, as well as the topography and hydrology of the area. This information is then used to determine the suitability of the site for effluent disposal and to identify any potential environmental impacts that may need to be addressed. The assessment also includes an evaluation of the proposed effluent disposal system, including the type of system, the location, and the design.

The results of the assessment are used to determine the most appropriate type of effluent disposal system for the domestic or commercial site, including:

  • Sewage Treatment Systems
  • Septic Tanks
  • Aerated Wastewater Treatment Systems (AWTS)
  • Advanced Secondary Treatment Systems (STS).
