Dear Cameron,

RE: Cooroy Mountain Spring Water
Access Arrangements and Trip Generation
Lot 2 SP 143409 at 314 Cooroy Mountain Road, Cooroy

| refer to our meeting with Council offices held on Monday 18" November 2013 and
further traffic engineering advice regarding the number of trucks generated from the
site and the access arrangements into the site.

The conditions of approval require a change due to ownership changes and changes
to the operational management of the business. The proposed bottling plant will be
scaled back and therefore changes to conditions, 5B, 5C, 5F, 5G, 8, 12 and 13 are
required as the specific numbers of staff and trucks has been reduced. From a traffic
engineering perspective a review of the existing access has been undertaken in order
to recommend an amendment to Condition 8 of the approval.

Condition 8

The applicant shall relocate the existing site to a location between 80 and 110
metres east of the existing access on Cooroy Mountain Road, to the
reasonable satisfaction of Council.

Proposed Development
The proposed development includes a bottling plant with between 3 to 5 staff
permanently on site.

 

RoadPro Development ABN 98 615 073 565
13492 Cooroy Mtn Spring Water Access Page | of 4

12

Page 15

The estimated trip generation from the site is expected to generate up to 40 truck
movements per week, including refuse collection, deliveries and water carrying
vehicles. This equates to 8 trucks per day or 16 trips (8 arrivals and 8 departures)
spread throughout the daily hours of operations 7:00am until 6:00pm, Monday to
Friday. It is also estimated the site will generate 10 to 15 light vehicle movements
per day including staff and ancillary business uses.

Assessment of Existing Access

The sight visibility has been reviewed in accordance with Clause 3.4 of Austroads
2009 Guide to Road Design — Part 4A: Intersections. Sight distance is measured along
the carriageway from the approaching vehicle to the conflict point.

The posted speed limit on this section of road is 60km/h. The safe intersection
sight distance (SISD) for an observation time of 3 seconds and reaction time of 2.0
seconds (Refer to Table 3.2 of Part 4) for 60km/h is 123m. The access intersection
meets this requirement to the west and achieves a sight distance of 130m. The site
distance to the east was measured to be 113m; however the additional 10m can be
achieved through the removal of vegetation within the road reserve as shown in red
in the photographs below. The vegetation is overgrown saplings only ranging in
trunk diameter of 50 to 150mm.

 

 

RoadPro Development ABN 98 615 073 565
13492 Cooroy Mtn Spring Water Access Page 2 of 4

Page 16

 

 

Photograph 2 — View looking west from Access

The access driveway location has been reviewed with consideration to the number
of vehicles accessing the site. The existing driveway has been operating adequately
for many years. The proposal meets the requirement for access driveway location in
accordance with Clause 3.2.3 and Figure 3.1 of AS2890.1:2004. Given the good sight
visibility, low traffic volumes and the existing local driver awareness of this access, it
is considered appropriate to retain the driveway in its current location.

The driveway has been assessed in regard to operational performance. According to
Austroads Guide to Traffic Management Part 3 — Traffic Studies and Analysis, Table
6.1, “At unsignalised intersections with minor roads where there are relatively low
volumes of cross and turning traffic, capacity considerations are usually not
significant and capacity analysis is unnecessary’. Table 2 below shows the volumes
where intersections operate adequately and capacity analysis is not required.

Roadway Capacity
Type of Road Light cross & turning volumes
Maximum design hour volumes
Vehicles per hour (two way)
Two Lane major road 400 500 650
Cross road 250 200 100

 

 

 

 

 

 

 

 

 

The traffic volumes for Cooroy Mountain Road are 500 vehicles per day with less
than 100 vehicles in the peak hour past the subject site.

 

RoadPro Development ABN 98 615 073 565
13492 Cooroy Mtn Spring Water Access Page 3 of 4

Page 17

The peak hour generation from the site is less than 20 trips per hour. Traffic volumes
are low and below the volumes stated in the table therefore, it is considered
unnecessary to undertake intersection analysis as the intersection operates with
uninterrupted flow conditions.

Therefore given the above assessment it is recommended that Condition 8 be
amended to allow the applicant to use the existing driveway to access the site.

If you require any further information, please don’t hesitate to contact me.

Yours faithfully

1.0 INTRODUCTION

1.1 GENERAL

Future-Plus Environmental (FPE) have been engaged by Cooroy Mountain Spring Water to
carry out a Site & Soil Investigation for on-site sewage treatment/disposal. The report has
been completed in response to the conditions stated in the Maroochydore Planning and
Environment Court Order dated 2"! August 2010 REF. The investigation was undertaken to
establish the design of an appropriate on-site sewage treatment facility and land application
area to service the existing developments on land described as Lot 2 on SP 143409 and located
at 314 Cooroy Mountain Road, Cooroy Mountain. A site locality plan is as shown in Figure 1

below.

Specifically this Report addresses the items detailed in Attachment A, Conditions 18A-B of
the Maroochydore Planning and Environment Court Order dated 2™ August 2010 and
Concept Effluent Treatment & Disposal Strategy Report Completed by Gilbert & Sutherland

It is understood that the owner proposes to upgrade the existing septic tank and trench system
to an aerated sewerage treatment plant (STP) and effluent disposal area, to service the existing
dwelling and daytime factory staff facilities as shown in the attached Site Layout Plan (refer
Figure 2). As part of the upgrade of the on-site sewerage facilities, FPE was engaged to carry
out an assessment of the on-site sewage treatment and potential disposal areas. This site and
soil evaluation report presents the on-site sewage treatment and effluent disposal area
required to cater for the existing development. The assessments and recommendations
contained within this report are based on our site assessment, information provided by the
Client and the recent geotechnical investigation carried out by Australian Soils Investigation

(ASD).

1.3 OBJECTIVES OF THIS ASSESSMENT
= Assess the suitability of the subject site for on-site wastewater disposal to be

undertaken in a sustainable manner, taking into account the climatic, topographical,
edaphic, and geo-hydrological characteristics prevalent on the sites;

= Identify any environmentally sensitive areas likely to be affected by wastewater
treatment and disposal activities;

= Identify the level of treatment necessary and method of disposal considered most
suitable for the site; and

= Identify and assess any potentially significant impacts on human health and the
natural environment that may occur as a result of wastewater treatment and disposal

options having regard to relevant legislative requirements.

1.4 REGULATORY REQUIREMENTS
A number of legislative requirements relate to on-site wastewater treatment and disposal

systems under Queensland legislation, along with various other standards and guidelines that
may place constraints on the suitability of the site for on-site wastewater disposal. Those

2.0 SITE ASSESSMENT

2.1 GENERAL
The assessment and recommendations contained in this report have been based on the recent

geotechnical investigations carried out and our recent site assessment of the existing sewage

infrastructure on-site.

2.2 PROPERTY DETAILS
The subject site is contained within registered allotment described as Lots 2 SP143409 and is

located at 314 Cooroy Mountain Road, Cooroy Mountain within the Sunshine Coast Regional

Council local government area. The area of the allotment is approximately 481 ,700m?.

2.3 EXISTING DEVELOPMENT
The site consists of an existing five (5) bedroom dwelling and the Cooroy Mountain Spring

Water bottling factory, which is utilised by five (5) daytime staff only. The site also contains

a series of free standing sheds.

2.4 PROPOSED DEVELOPMENT
The owner proposes to direct all wastewater generated by the existing dwelling and factory

office facilities to a centralised STP and effluent disposal area.

2.5 TOPOGRAPHY
The subject allotment is situated over a varying topography with a slope of 5-20% from east

to west, towards the existing creek located in the western portion of the property. The
Sunshine Coast Regional Council online mapping facilities illustrate a site elevation between
110 to 280m AHD.

2.6 SITE HYDROLOGY
It is likely that the majority of rainfall on the site will be absorbed into the soil. However,

during extended periods of heavy rainfall, excess rainfall not adsorbed into the soil profile is
likely to flow towards the watercourse located in the western portion of the property, running

parallel with Cooroy Mountain Road.

2.7 SUB-SURFACE CONDITIONS
A preliminary geotechnical investigation for effluent disposal assessment including

percolation testing was recently carried out within the locations indicated on the Borehole

Location Plan (Figure 2). A total of two (2) boreholes were advanced across the site to a

depth of 2.0metres below the existing ground level (refer Appendix A).

Based on the geotechnical investigation, it is noted that the soil profile encountered within the
site generally consisted of 700mm of moderately structured Silty Clay (Category 4-5)
overlying strongly structured Silty Clay (Category 6) to termination depth at 2.0m.

2.8 SOIL PERMEABILITY
In addition to the soil borehole logs, one (1) permeability test was undertaken within one of

the two boreholes and in accordance with the AS/NZS 1547:2000 to determine the actual
permeability of the site soils. The recorded KSAT value was 0.0213m/day which indicates

that the site soils are subject to very low permeability.

2.8.1 Groundwater & Water Bores
During the site investigations, no permanent water table or seepage was encountered within

the boreholes. However, groundwater table represents local groundwater accumulations that
typically fluctuate between seasons. Therefore groundwater separation distances based on the

local water table depths needs to be considered during the design of on-site sewage systems.

3.0 EFFLUENT QUALITY AND QUANTITY

3.1 ASSESSMENT OF SOIL AND GROUNDWATER CONDITIONS

The soil and percolation test results indicate that the soils at the site are relatively
impermeable but is however still suitable for on-site sewage treatment and effluent disposal.
Groundwater or seepage was not observed within the boreholes carried out during the recent

site investigation.

Given the relatively poor permeability of the site soils and the presence of medium to heavy
clay soils which are more representative of Category 6 soils, the on-site wastewater
assessment for this site is based on Category 6 soils although the Borehole logs indicate the

presence of Category 5 top soils.

3.2 SYSTEM SELECTION
In order to minimise potential impacts on local water quality and to maximise the potential

reuse of treated effluent, it is recommended that all wastewater generated from the
development be treated to a minimum secondary standard. It is understood that all wastewater
generated from the dwelling and factory office facilities will be diverted to the existing septic
tank located geographically downslope of the waste generating facilities. It is proposed that
the existing septic tank will be converted to a pump station, with all collected wastewater to

be pumped to a STP capable of treating the wastewater to a minimum secondary standard.

Typical quality criteria for secondary and advanced secondary treated effluent nominated in
the Department of Infrastructure and Planning, Queensland Plumbing and Wastewater Code

are summarised in the following table:

3.3 HYDRAULIC LOADING

The hydraulic loading for this site was calculated based on the anticipated population
intensities within the factory office facilities and the five (5) bedrooms contained with the

existing dwelling, as provided by the Client (refer Table 2 below).

Table 2: Proposed Population Intensities for the subject site

 

Sec) Proposed Population

5 persons per day (during standard
daytime operating hours)

Five (5) Bedroom Dwelling 8 persons

Factory Office Facility

 

 

 

 

 

The hydraulic loading associated with the proposed development intensity mentioned above
can be calculated using Appendix 4.2D of AS/NZS 1547:2000 based on a typical wastewater
flow allowances generated from rural factories and domestic dwelling. For rural factories this
typically ranges from 30L/P/day for on-site roof tank water supply to S5OL/P/day for
reticulated community water or bore water supply as per AS/NZS 1547:2000. The typical
wastewater flow allowances for a domestic dwelling with bore water supply and standard
water reduction fixtures is typically 145L/P/day as per AS/NZS 1547:2000. The estimated
hydraulic loading associated with the development intensity has been calculated in the table

below:

Factory Office Facility § 50* 250
Five (5) Bedroom Dwelling 8 145 1,160
Total Estimated Daily Flows 1,410

 

 

 

Based on the above, a total maximum hydraulic loading of 1,410 litres (8 Equivalent Persons

- EP) per day may be generated from the combined use of the facilities on-site.

Based on the estimated daily flow of 1,410 litres (8 EP) per day, the site does not trigger an

application for an Environmental Relevant Activity 63(1)(a)(i) identified as;

Operating sewage treatment works, other than no-release works, with
a total daily peak design capacity of 21 to 100 EP if treated effluent is

discharged to an infiltration trench or irrigation scheme.

If additional people are using the site and/or water conservation is not being practiced within
the building and additional flow is being generated, enlargement of the STP and irrigation

area may be required. This will be additional cost to the owner.

3.4 TREATMENT SYSTEM
Treatment of wastewater must achieve a minimum of secondary or advanced secondary

effluent quality in accordance with the Queensland Plumbing and Wastewater Code 2011.

Treated Wastewater shall comply with the following quality criteria specified in Table 1.1 of
the Queensland Plumbing and Wastewater Code, which are as follows:

» BODs < 20mg/L

» SS <30mg/L

» Thermotolerant Coliform (org/100mL) < 200

3.5 ADDITIONAL DESIGN CONSIDERATIONS
A number of other design considerations should be made in relation to the following key

elements associated with this project.

Peak Flows and Low Flows
The wastewater treatment plant must be able to cope with periods of sustained high or peak

loads and also periods of very low influent. During these times, appropriate flow balancing

may be necessary in order to buffer against such extreme variable conditions.

Effluent Quality & Concentration
Developments with mixed uses produce (Factory Office Facility) a different type of

wastewater when compared to traditional domestic effluent. Typically, this effluent can be

more concentrated and require specific design considerations.

4377-131119-1.0 G

Alarms and Early Warning Systems
It is recommended that a high level and failure alarms with battery backup be considered as

 

part of the overall design for the pump station and STP.

Service and Maintenance
The service and maintenance provide must attend and complete the required service,

maintenance and monitoring of the STP on a minimum 3 monthly basis.

Grease Trap
The existing grease trap is to be inspected by a suitable qualified person to ensure the

integrity of the unit, as it is recommended that pre-treatment of the effluent be undertaken,
given the nature of the wastewater likely to be generated by the development. The grease trap
should then be adopted as part of the operation and maintenance of the facility and require

regular inspection, service and maintenance.

4.0 RECOMMENDATIONS

4.1 EFFLUENT DISPOSAL
It is recommended that the application of effluent on-site via surface irrigation be adopted.

Contained in Figure 3 of this report is the proposed location of the effluent application areas

and the irrigation system design detail.

Assuming a hydraulic loading of 1,410 litres per day and a DIR of 15mm/week based on
Table 4.2 A4 of AS1547:2000 (Category 6 soils), a minimum application area of 658m? is

required.

Table 4: Minimum Required Irrigation Area

Irrigation Area

Subject Site Slope

Lot 2 SP143409 Soil Category 6

 

 

Based on the Table above and presence of Category 4-5 soils to 700mm, an effluent irrigation
area of 625m? is required for the site. A typical design detail of the irrigation system is shown

in Figure 4.

It is noted that the site has sufficient space available for a 100% reserve area and is shown in

Figure 4.

The application area shall be installed in accordance with the following:
1) All plumbing and drainage work is to be carried out by licensed persons and strictly in
accordance with the AS/NZ 3500:2003, AS/NZS 1547:2000 and Plumbing and Drainage
Act 2002;
2) Lilac stripe poly pipe is to be buried a minimum of 150mm below ground level from the
treatment plant to the irrigation area;
3) Sprinklers are to be used to irrigate the treated effluent within the designated area after

150mm of mulch or turf has been applied;

4) Any depressions within the surface application area are to be filled with soils of same

category at horizon A.

5) Effluent warning signs must be clearly displayed in at least two places beside all

application areas.

The required setback distances as nominated in the Queensland Plumbing and Wastewater

Code 2011 have been summarised in Table 5 of this report.

4,2 MEDLI ASSESSMENT

Based on the resent investigation under by Future-Plus Environmental, in accordance with the
relevant legislation and guidelines, it was deemed unnecessary to undertake a MEDLI

assessment for the site. Rather the detailed site assessment has been undertaken in

accordance with the QLD Plumbing and Wastewater Code and AS:NZS1547:2000.

4.3 SETBACK DISTANCES

The setback distances from the effluent disposal area shall comply with the Queensland

Plumbing and Wastewater Code which is summarised below:

4.4 STORMWATER DRAINAGE

Issues relating to surface flows may become prevalent within the disposal areas during
extended periods of rainfall. Accordingly, it is recommended that a cut-off drain or diversion
drain/mound is constructed upslope of the disposal areas to collect and divert any
surface/subsurface waters away from the disposal area. A retention mound is to be

constructed downslope of the land application area to prevent any surface water from exiting

the designated disposal area.

All stormwater runoff from the roof of buildings and pavement areas associated with the

development on the site should not be discharged in a concentrated form onto the effluent

disposal areas.

5.0 CONCLUSION

This report presents recommendations on the sizing of an effluent disposal system (surface
irrigation) 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 500m? 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;
