Recommendations:

Based upon our Site and Soil Assessments we recommend the following method of On-Site Effluent Disposal
should be used.

For the treatment of the Effluent we recommend;


      Advanced Secondary WasteWater Treatment System (AWTS)
(NOTE: The system chosen must satisfy both the Queensland Plumbing and Wastewater Code and AS 1547-2012
On-Site Domestic Waste Water Code and be approved for use by the Local Shire/Council governing the allotment.)

For the disposal of the treated effluent within the Land Application Area we recommend;

      A Pressurised Sub-Surface Reticulated Irrigation System
