On-Site Effluent Report

1.0          COMMISSION:

Our commission was to carry out Site Soil Assessment on the above site and make recommendations for the
disposal of domestic wastewater for the proposed lot reconfiguration. It is proposed to reconfigure Lot 2 on
SP199340 into allotments, namely Lots 1 & 2. The site work was performed in accordance with AS 1547-2012, on
the 03/03/2026.

The client has provided plans of the proposed subdivision.


2.0          TESTING PROGRAMME:

The above site is located within the Noosa Council

During our site evaluation consideration was given to the following:

           the available area for the primary siting of absorption areas and alternative sitings.

           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

Three test holes were excavated within each allotment 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.


3.0          SITE DESCRIPTION:

The allotment is vegetated with grasses and scattered low lying trees. All falls are towards the rear of the
allotment. The surface profile in lots 1&2 is linear planar with the ground profile. This profile then feeds into a
seasonal gully and Dam at the rear of the allotments .


3.1 GEOLOGY & TOPOGRAPHY

A desk top study of the site confirms the following:-

      -    Reference to the Australian Geological Map 1:100000 Gympie Special confirms the site is located within the
           Tiaro Coal Measures of the late Early Jurasic period, consisting of Sandstones , siltstone, shale, coal and
           ferrginous oolite marker.


      -    Reference to Sunmap 1:25000 topographic maps confirm the site is located on the Cooroiibah plain and is
           surrounded by gully formations and creek.
