Site and Soil Evaluation

ON-SITE EFFLUENT DISPOSAL REPORT:                          Lot 77 on MCH546
                                                           42 Lukes Road, Cooroy.
Introduction:

Australian Soil Investigations have conducted a Site and Soil Assessment at the above allotment for the purpose of
determining the most suitable means of on-site effluent disposal. On-site testing for this assessment was
performed in accordance with AS 1547-2012-“On-Site Domestic Wastewater Management and the Queensland
Plumbing and Wastewater Code. Field work for this assessment was undertaken, on the 28/04/2022.
ASI has been asked to provide a design for a five bedroom dwelling and a workers cottage for ten people
max.

Site description:

The allotment is located within the Noosa Regional Council and is contained within a rural area.
The slope within the allotment is generally linear. The slope within the area best suited for effluent disposal is in
the order of 5%.

On-Site Assessment:

During our site evaluation consideration was given to the following:

        the available area for the primary siting of absorption areas (Land Application Area) and alternative
         sightings.

        the risk of prejudicing adjoining property and underground water supplies, by seepage or run off from the
         site.

        permeability, soil type and soil depth.

        drainage, and envisaged seasonal changes in ground water level.

        general climate.

        slope and the effects of seepage and water run-off from surrounding higher ground.

On-Site Testing:

Three test holes were excavated in the positions shown in the attached site sketch. These holes were 100mm
diameter x 600 mm deep for the purpose of site soil assessment in accordance with the AS 1547-2012. A further
100mm diameter hole was excavated to determine the soil profile. The site was then classified in accordance with
AS 1547–2012 On-Site Wastewater Management for the purposes of effluent disposal.
