ON-SITE EFFLUENT DISPOSAL REPORT:                          340 Pomona Kin Kin Road, Pinbarren.

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 1547-2000-“On-Site Domestic Wastewater Management and the Queensland
Plumbing and Wastewater Code. Field work for this assessment was undertaken, on the 10/04/2018. This
assessment has been based upon the proposed plans, provided by the client. Design parameters will be based on
these hydraulic requirements.
It is proposed to construct six cabins for holiday occupation. Three four bedroom cabins and two one
bedroom cabins. Total population equivalent to 20 persons.

Site description:

The allotment is located within the Noosa 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 6%.

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 - 2000. A further
100mm diameter hole was excavated to determine the soil profile. The site was then classified in accordance with
AS 1547 – 2000 On-Site Wastewater Management for the purposes of effluent disposal.
