1.0 Introduction:
Biowater Designs Pty Ltd, in accordance with AS/NZS1547-2000 ( Domestic Wastewater Management ) and the
Queensland Plumbing & Wastewater code (QPW), was commissioned to undertake a Site & Soil Evaluation in the
Noosa Council at 328 Upper Pinbarren Creek Road, Pinbarren.
The results form the basis of our recommendations for on site wastewater disposal.
Our Site investigation and field work was performed on Friday 15th February 2019 after a period of wet weather.
The investigation was undertaken to determine the soil profile and Long Term Acceptance Rate (LTAR) of the site in
order to accommodate proposed amenities (shower, toilet and 2 handbasins) in a shed/workshop and future stables with
a washing machine and handbasin. No kitchen facilities or bedrooms to be installed.
NOTE: This evaluation was undertaken at the owner’s request after considerable discussion regarding environmental
issues of this site and preferred design of the Land Application Area.
2.0 Site Description:
2.1 Existing Buildings: Dwellings & Sheds. The existing dwellings do not form part of this assessment.
2.2 Site Factors:
The site is a large acreage allotment the area is 256269.38m2.
The proposed Land Application Area is slightly sloping (3%) to the South-East.
The proposed Land Application Area has very good exposure to sun and wind.
Erosion, mass movement or land slip was not observed on this site. Rock outcrops are not evident on this site.
Vegetation on this site consists of small to large trees and shrubs of various species and has 100% grass cover.
There are no bores on this site or adjoining properties within the required setbacks of the proposed Advanced Enviro-
Septic Bed.
There is a small creek at the front of the property, several dams and intermittent waterways across the site. Setback
requirements under ASNZS 1547:2000 for Advanced Secondary Effluent are obtainable.
Ground water was not encountered on this site during our investigation to a depth of 1500mm.
There is no evidence of fill in the proposed Land Application Area.
Rain water will transverse this site from adjoining properties during heavy rains.
Concentrated run-off from this property will transverse adjoining properties during heavy rains.
Soils were moist and there is no evidence of soil surface cracking. No evidence of compaction or seepage areas.
Salinity is not evident.
3.0 Soil Investigation:
3.1 Drainage Pattern: Linear Planar
3.2 Method:
Soil Testing for the site was conducted by Global Testing on 29th January 2019 to a depth of 1500mm. See borelogs attached.
The soils were visual one textually classified in accordance with AS/NZS 1547:2000. The soils were
predominately red/brown in colour. Strongly structured Sandy Clay.
Forms a plastic ball in which sand grains can be seen; felt or heard; forms a ribbon
50-75 mm long. Category 5 adopted.

4.0 Recommendations:
4.1 Treatment Facility:
The on-site treatment facility to service the new detached dwelling is to be an Advanced Enviro-Septic System (AES).
This system has a Chief Executive Approval # 14/2014 for Advanced Secondary Effluent. The Equivalent Person
(EP) for this system is to be no less than 2.
A new min 3000lt septic tank is to be installed to service the amenities in the shed/workshop and stables. This tank
must comply with AS/NZS:1546. All wastewater from these amenities is to be directed to the septic tank then to the
AES bed.
The Land Application Area is to be an Advanced Enviro-Septic Infiltration Bed of 24m2.
5.0 Design Calculation
The serviceable life of the Land Application Area will be compromised if the design flow is exceeded. Any
proposed changes to the position of the Land Application Area, System Type or House Design will require a
reassessment of this site. For our calculations we have assessed the design flow as follows:
Design Calculation
DLR (mm/d) (secondary quality effluent) 10
Hydraulic load (lt/day/person) Tank Water / 1 bedroom equivalent 120
Design Flow Q (lt/day) EP: 2 240
Design sizing calculation L = Q /(DLRxW)
= (240 / 10)
Disposal area A+B (square metres) AS/NZS1547:2000 24m2
Nominated Configuration (metres) AES System Design Calculations = 6.6 x 3.64m (L xW) 24m2

5.1 AES Infiltration Bed Design. Advanced Enviro-Septic System
The AES Bed Design is to be a gravity fed, belowground system. See system design drawings page 6.
The total bed base required is 24m2 (6.6m x 3.64m). Bed is to be installed as shown on the site plan. See drawings page 6 for bed
profile. A minimum 4m setback is required to any tree.
The entire bed base it to be ripped 300mm parallel to the AES pipes and gypsum applied at 1kg per m2.
Coarse washed sand will be referred to as “system sand” and must meet the specifications of the system manufacturer.
System sand will need to be placed around AES pipework and for the infiltration area as shown on the attached drawings.
System pipe bed dimensions (Area A) are 6.6m long by 1.35m wide and a total minimum sand depth of 750mm. 300mm of
course washed sand is to be spread to form a base and 2 rows of 2 lengths of AES pipes installed as per the attached drawings.
A further infiltration area 6.6m x 2.29m (Area B) is to be constructed below the pipe bed as per the site drawings and a minimum
of 150mm system sand to be spread over the entire infiltration area.
Pipes are to be covered by a minimum of 150mm of system sand. A further 150mm of site soil is to be mounded over the sand to
prevent surface water entering the bed. After all settlement the AES Bed is to have a minimum 150mm cover of site soil.
Beds are to be constructed in accordance with the AES Design and Installation Manual and all plumbing works in accordance with
the QPW code. All site work is to be carried out by a licenced plumber and all AES horizontal pipes laid with the aid of a laser or
dumpy level to ensure absolute compliance with the manufacturers installation guidelines. This is critical for correct operation.
Oxygen Demand Vents are to be installed as per the AES Design & Installation Manual. The high vent (100mm) to be installed
on the shed/workshop must be a minimum of 3m higher than the AES low vent and provide unrestricted air flow through the
entire system. (See attached drawing for illustrations.)
Two Inspection Ports are to be installed, one in the centre of the pipe bed and another at the furthest point from the influent to AES
Pipes. See Installation Instructions Appendix A - page 9.
Care must be exercised to prevent machinery access on the AES bed during and after construction.
