5.0 CONCLUSION
This report presents recommendations on the sizing of an effluent disposal system (surface

inigation) to cater for the combined use of the existing development and the population
intensities associated with this.



The assessments and recommendations are based on our site assessment and the geotechnical

investigation carried out.



On the basis of the geotechnical investigations and assessment of the flow rates, the subject

allotment is considered suitable for on-site sewage operations within the site. An effluent

irrigation area of approximately 500m2 will be required to adequately dispose the treated
wastewater generated from the development intensity.



Provided the on-site sewerage facility is installed in accordance with the recommendations

provided and relevant codes and standards aforementioned in this report, there will be

minimal risk of environmental impact to the site and surrounding areas. The on-site STP and

effluent disposal area will need to be managed intensively to minimise potential human health
risks and thereby protect and enhance the quality of human health and the environment in the
long term. The system must be operated and maintained in compliance with the

manufacturer's guidelines (information should be sought from the treatment system

manufacturer), to ensure this risk is appropriately managed.



All wastewater should be treated to a minimum secondary or advanced secondary level to

reduce any potential environmental impacts.



Details of the wastewater treatment plant and land application system are summarised below;
