             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 Surface Reticulated Irrigation System
