Summary

This report describes the proposed wastewater loadings, treatment method and disposal
strategy for the redeveloped Cooroy Mountain Spring Water bottling facility, Lot 2 SP143409,
314 Cooroy Mountain Road, Mt Cooroy, Queensland.

An Effluent Disposal Report has been previously prepared for the site as part of the MCU
Development Application. This current conceptual assessment constitutes a revision of the site
effluent treatment and disposal strategy in accordance with AS/NZS 1547:2000 ‘On-site
domestic wastewater management’ and the experts agreement dated 2 September 2009, and
refers to the findings of the previous report where relevant.

In performing this assessment site physical characteristics and site soil suitability have been
reviewed.

An approved secondary wastewater treatment system will be used to manage wastewater
generated by the development. An irrigation area of 1,180m? will be required to assimilate the
proposed volume of treated wastewater. We consider there is sufficient land area on the site to
accommodate the irrigation area and an increase in area if required.

This report concludes that sustainable irrigation of treated wastewater within the site, in
accordance with the advice contained herein and applicable guidelines, is achievable.

As this is a conceptual design, a further detailed effluent treatment and disposal strategy

including MEDLI modelling will need to be prepared to support future operational works
applications for this site.

SP143409, 314 Cooroy Mountain Road,
Cooroy Queensland (‘the site’). The site
occupies a total area of 48.17 hectares and
is shown on Drawing HJ0085.1.1.

An Effluent Disposal Report was previously
prepared for the site by Global Testing Pty
Ltd in 2007'.

This current assessment constitutes a
revision of the site effluent treatment and
disposal strategy in accordance with AS/NZS
1547:2000 ‘On-site domestic wastewater
management’ and the experts agreement
dated 2 September 2009.

The issues raised in the Report of Experts
Meeting September 2, 2009 relevant to this
conceptual assessment are reproduced
below.

° An updated effluent treatment and
disposal strategy (ET&DS) is
required for the project, to
demonstrate that adequate
treatment of wastewater from
plant and wash down, and from
staff and suitable on site disposal,

GILBERT+SUTHERLAND,

taking account of current plant
staffing and waste generation
figures. A conceptual ET&DS
should be completed by G&S to
support the current application, to
outline EP's to be treated,
treatment process, and disposal
areas and locations. This work
should include suitable sampling
and testing of the current waste
stream discharge, appropriate to
the relevant sources.

A further investigation of actual
EP's being generated by the
combination of plant, wash down
and staff wastewater is to be
carried out by G&S to support the
current application, and to assess if
additional ERA licensing is required
for the site.

In performing this assessment site physical
characteristics and soil suitability have been
reviewed.

2) Proposed development

The proposed development the subject of
the MCU application consists of:

a single on-site residential dwelling,
a steel framed shed complex containing
bottle wash and filling areas, storage
area, holding tanks and loading areas,
© areas of hardstand surrounding the
above shed for car parks, loading bays
and site access; and
¢ office wing including reception,
administration and staff amenities.

Drawing HJ0085.1.5 shows the proposed
redevelopment layout.

GILBERT+SUTHERLANG

It is proposed that wastewater generated
by the redevelopment will be treated to a
secondary standard before being irrigated
onto an appropriate disposal area which
meets all planning requirements.

The calculation of the wastewater loadings
used in this assessment is detailed in Section
5 of this report. The anticipated wastewater
loadings from the development will be
equivalent to a 17 EP sewage treatment
system. Therefore, this proposal will not
require an ERA63 licence.

3) Site characteristics

3.1 Site location

The proposed development site is located
at 314 Cooroy Mountain Road, Mt. Cooroy,
Queensland. The site is properly described
as Lot 2 on $P143409, Parish of Tewantin.

3.2 Geology

A review of the Queensland Department of
Mines and Energy 1:100,000 Gympie Special
Sheet? geology map indicates that the
elevated sections of the site are underlain
by Tertiary Rhyolite formations while the
Jower portions of the site surrounding
waterways are located over early to middle
Triassic Arenite, Argillite and Phyllite of the
Kin Kin Beds formation.

3.3 Soil classification

While no on-site soil studies have been
undertaken by Gilbert & Sutherland as part
of this assessment, the above geology is
known to give rise to a number of soil
types’.

Soils based on Tertiary Rhyolite formations
are generally acidic in nature and produce
Tenosols, Sodosols and Kurosols.

Kin Kin bed derived soils tend not to be as
acidic and have been found to produce red
and yellow Chromosols and Tenosols.

A detailed soil survey and permeability
testing would be undertaken as part of the
detailed assessment at Operational Works
application stage.

3.4 Topography and drainage

Elevation at the site ranges from
approximately RL105 metres along the
central waterway to greater than RL140
metres in the steeper south-eastern and
eastern portion of the site. The slopes are

typically ‘very gently inclined’ (<3%) to
‘moderately inclined’ (>20%).*

Runoff from the site flows towards a small
un-named waterway flowing across the
site. This waterway flows from the south-
west corner of the site toward the north-
east and eventually onto Lake McDonald.

A number of small dams are located on-site
which serve to provide water for grazing
stock and capture site run-off for irrigation
of landscaped areas.

3.5 Vegetation

With the exception of the relatively smalt
The majority of the site is cleared and
covered by pasture grasses for cattle
grazing purposes. The bottling facility site
was also previously cleared and planted to
pasture for this purpose.

A significant area of mature trees and other
planted vegetation is located to the east of
the bottling facility and incorporates the
eastern drainage line, with scattered
riparian vegetation (both pre-existing and
planted) occupying the banks of the main
tributary to the west of the bottling facility
and towards the northern boundary. This
vegetation is currently mapped as regrowth
area under the Queensland Regional
Ecosystem (RE) classification.

Further dense vegetation exists on the
eastern boundary which is mapped as
dominant “Of Concern” and remnant “Not
of Concern” under the Queensland
Regional Ecosystem (RE) classification.

4) Previous assessment

The outcomes of the previous assessment
by Global Testing are as follows.

4.1 Wastewater loading

At the time the report was prepared the
predicted wastewater loading was a total
of 1950L/day comprised of:

* 900L/day from the existing 3
bedroom household; and

¢ 1050L/day from the extended
bottling facility (21 persons @ 50L
per person per day).

4.2 Soil types

Soil encountered at the site of the
proposed irrigation area was defined as a
moist brown silty, sandy clay overlying a
moist red/brown silty, sandy clay. No
indication of soi! structure was given.

 

4.3 Permeability

Three separate infiltration tests were used
to determine that the average permeability
for the chosen disposal site was 0.22m/day
and consequently a design irrigation rate
(from AS1547) of 20mm/week was adopted.

4.4 Irrigation area

Based on the above information Global
Testing recommended that a gypsum
treated surface spray irrigated area of
683m? would be sufficient to assimilate the
wastewater generated.

In accordance with the required Noosa
Shire setback distance for properties
located with the Lake MacDonald
catchment the proposed area was to be
jocated near the western lot boundary to
the south of the access road.

5) Effluent treatment
system and land
application area

This Conceptual Effluent Treatment and
Disposal Strategy was conducted using a
combination of new data and data taken
from the previous site investigation
undertaken by Global Testing in 2007.

The proposed treatment and application

methods to be employed on-site are based on

the following guidelines and authorities:

« the ‘Queensland Plumbing and
Wastewater Code, 2006’

© AS/NZS 1547:2000 ‘On-site Domestic
Wastewater Management’ 5

* Planning Guidelines for Water Supply and
Sewerage ©

* Queensland Water Recycling Guidelines,
2005.’

Based on previous testing detailed in
Section 3 of this report and the proposed
site use, it is proposed that the most
effective and flexible method of irrigating
treated wastewater for the site would be
via surface sprinkler.

In calculating a suitable disposal area for
the predicted wastewater loadings, the site
was assigned a conservative permeability of
0.22m/day in accordance with Category 5
soils as detailed in Table 4.2A4 of AS/NZS
1547:2000. A conservative proposed
irrigation area for the expected effluent
Joadings was therefore calculated
incorporating the recommended design
irrigation rate (DIR) of 20 mm/week for a
category 5 soil from Table 4.2A4 of AS/NZS
1547 (2000). This is detailed in Section 5.4.

5.1 Wastewater loadings

The following proposed wastewater
loadings are based on interviews with

activities at the redeveloped site during the
peak summer period when the facility is

*Assumes 11/5.5 dual flush cistern, with 1 fult
flush and 3 half flushes per person per day.
** Assumes 4 x 2L washes per day.

 

 

For the on-site residence it is assumed that
it will be a permanent 5 person household
connected to a bore water supply (i.e.
180L/person/day).

For the bottling facility and administration
block, the above loadings assume a total of
50.5L/person/day. This is in line with the
loadings for industrial use (50L per person)
from AS1547:2000. .

5.2 Bottling facility wash down

In addition to the above tabled wastewater
generation projections there is a volume of
water used on a weekly basis to hose down
the internal shed floors. This is performed
once a week using a pressure cleaner to
conserve water and expedite the task.

This water is currently collected in a
connected series of concrete drains
embedded in the shed floor. It is proposed
that these will drain to a central
underground sump equipped with a pump
and float switch to enable the contained
waters to be pumped to the effluent
disposal system as the sump level requires.

Assuming that the pressure cleaner uses
600L per hour and the wash down takes
half an hour, it is estimated that the

5-1

Page 27

 

Cooroy Mountain Spring Water CEDA Cooroy Mountain Road, Mt. Cooroy QLO

volume of water required undertaking this
task will be 300L per week or an average of
43L per day. Added to the total above the
total volume of wastewater to be treated
will be 3,367Uday.

Wastewater loadings from the bottling
plant process are dealt with in the
Conceptual Stormwater Assessment report
by Gilbert & Sutherland (2009).

5.3 Licensing requirement

Using the formulae presented in the
Queensland Environmental Protection policy
(Water) 1994 - Environmental Protection
Regulation (2008) Section 63, one Equivalent
Person (EP) generates 200L per day. Thus the
proposed development will require a ~17 EP
wastewater treatment system. As this is less
than the 21 EP threshold the system does
not constitute an Environmentally Relevant
Activity (ERA) 63 licence and does not
require Department of Environment and
Resource Management (DERM) approval.

5.4 Proposed wastewater
treatment system

It is proposed that wastewater generated
on-site will be treated to a secondary
standard within a water treatment plant
(WTP) utilising either of the following
treatment methods:

* activated sludge system

* biological trickling filter system

* extended aeration system

* aerated/aerobic sand filter system

5.5 Proposed method of disposal

It is proposed that the treated effluent
from the bottling facility redevelopment
will be surface irrigated onto a designated
irrigation area.

The surface-spray irrigation system
proposed will allow regular small
applications to be applied to the
nominated irrigation area to maintain
optimal soil moisture levels while
minimising deep percolation and surface
run-off. Additionally, surface spray
applications maximise evaporation further
assisting with wastewater disposal.

All such irrigation would be undertaken in
accordance with the requirements of the

5-2

Queensland Water Recycling Guidelines and

AS/NZS 1547:2000, including the following:

+ The designated land application area must
comply with setback distance
requirements.

+ The presence of buried pipes shall be
indicated by using underground marking
tape to AS/NZS 2648.1 or be indicated by
warning signs at the boundaries of the
designated area, clearly visible to property
users, which would read in English and
any other appropriate community
language: ‘Sewage effluent pipework
installed below. DO NOT DIG’.

+ Warning signs should be erected near the
wastewater treatment system, be clearly
visible and read in English and any other
appropriate community language:
“RECYCLED WATER BEING USED - DO NOT
ORINK’.

+ All recycled water signs should comply
with AS1319-1994 Safety Signs for the
Occupational Environment.

« No run-off or seepage of effluent should
occur beyond the designated irrigation
area.

+ Effluent must not come into contact with
people, domestic or farm animals or any
crops intended for human consumption.

+ The owners of the system must enter into
@ contract with an organization
authorised by Council and/or EPA for the
servicing of the unit on a regular basis.

+ The land application area/s should be
maintained with purposely planted
grass/turf or trees/shrubs to maximise the
nutrient uptake and minimise deep
percolation of nutrients through the soil
profile.

5.6 Proposed irrigation area

In order to estimate an appropriate land
application area for the expected loadings,
the method of catculation for an irrigation
area from AS1547—1994 was used.

The equation for sizing a surface irrigation
area from Section 3.6.2(c) of AS1547—1994
is as follows:

Ai = qw/DIR

Where

Ai = irrigation area required
qw = total quantity of effluent

generated in a week, in litres

Page 28

| DIR = = design irrigation rate in mm/week

Therefore:

qw = 3,367L (from Table 5.1.1) x 7 days

t = 23,569L/week

ro DIR = 20mm/week (adopted from Global
' Testing report in Section 3)

I Ai = 23,569/20 = 1,180m?

| Assuming the conservative DIR of
20mm/week determined above, a minimum

| of 1,180m? is required for irrigation.

| Drawing number HJ0085.1.5 shows the

proposed redevelopment layout and
proposed irrigation area locations.

5.7 Buffer distances

must have signage in accordance with
AS/NZS 1547:2000.

5.8 Additional buffer requirement

Further to the above recommended setback
distances the Noosa Shire Plan Planning
Scheme Policy 24 - Effluent Disposal
(effective February 3, 2006) requires that all
effluent disposal irrigation areas are to be
located not less than 100m from any
permanent or intermittent watercourse.

To this end it is proposed that the irrigation
area for this site will be located near the
western fot boundary to the south of the
access road, See Drawing No.HJ0085.1.6 (at
the end of this section).

6) System maintenance

6.1 Disinfection

Where effluent is irrigated across the
ground surface, disinfection is considered
necessary and may include chlorine
addition or the use of UV, Ozone or
membrane technology.

6.2 Unit maintenance

To reduce any risk associated with the
operation of aerobic treatment plants, they
must be maintained regularly by a
registered service agent so that the
discharge criteria for the reclaimed effluent
are satisfied at all times. This maintenance
must be carried out in accordance with the
requirements of the manufacturer and to
the satisfaction of Council.

As part of the quarterly service, studge and
scum levels should be monitored.

Anaerobic chambers should be desludged
by an approved contractor, as required.

GILBERT+SUTHERLANG

6.3 Maintaining the land
application area

The fand owner or occupier is responsible for
the maintenance of the land application
area and should ensure ponding and runoff
from the area does not occur.

The irrigation area requires regular
harvesting (mowing/pruning) and removal
of clippings to ensure that nutrients are
removed from the system and to promote
continued growth, nutrient assimilation
and water uptake. A high level of ground
cover must be maintained at all times to
minimise potential erosion.

The land application area must be inspected
regularly to assess its physical condition. The
most obvious signs of system failure would
be odour or surface ponding of water. Any
irrigation area rectification work is to be
performed by a licensed drainer.

7) Conclusions

A conservative assessment of site
conditions was undertaken to determine
its suitability to accept on-site disposal of
treated wastewater generated by the
proposed bottling facility development.

An approved secondary wastewater
treatment system will be used to manage
wastewater generated by the development.

An irrigation area of 1,180m? will be
required to assimilate the proposed volume
of treated wastewater based on the
conservative loadings of 3,367 week.

The size of the site will ensure this area is
available and that an increase in area is also
possible if required.

GILBERT+SUTHERLANG

This report concludes that irrigation of
treated wastewater within the site, in
accordance with the advice contained
herein and applicable guidelines is
achievable.

As this is a conceptual design, a further
detailed effluent treatment and disposal
strategy including MEDLI modelling will
need to be prepared to support future
operational works applications for this site.
