EXECUTIVE SUMMARY

The Online Water Quality Monitoring Strategy (LWA, 2013) identified 12 sites where real-time water quality

monitoring could further enhance Logan City Council’s ability to monitor network water quality. Detailed

planning for ten of these sites has been addressed as part of this current detailed planning study, while two

sites are already being delivered by LWA as part of Work Package WP7635 - Travis Road Reservoir outlet

main.

There are 11 existing online water quality instruments within Logan North and Logan East; however, there is

only one instrument installed within the Logan South network. LCC currently relies upon manual sample

collection and laboratory testing to identify issues with water quality within Logan South, which typically takes

up to one week to identify and respond to any issues. This process limits Council’s ability to respond in a

timely manner to potentially critical events in the water supply network.

The Online Water Quality Management Strategy (LWA Task 90-11-48) identified beneficial locations for

sampling within the LCC water supply area to improve the real time collection of water quality data, and also

reviewed parameters for monitoring. The parameters to be monitored at the proposed sites include:

pH

Temperature

Free Chlorine

Total Chlorine

Nitrate (3 sites).

A review of instrumentation suppliers was undertaken in this current study to determine equipment

availability and cost based on formal quotes from suppliers and has refined instrumentation costs and

specific equipment requirements for the proposed monitoring sites. Detailed planning has been undertaken

for each site by examining constraints and opportunities to determine the preferred location of the water

quality (WQ) cabinet. An environmental, town planning, cultural heritage assessment and a first principles

cost estimate were also undertaken for the sites.

Concept layout plans showing cabinet and conduit locations have been prepared for each of the sites based

on a detailed assessment of the known risks and constraints.

The key findings of this study are:

In general there was minimal constraint for the installation of the water quality monitoring cabinets at

each of the proposed sites. There were no environmental or town planning approval issues which

would prevent installation of the WQ cabinets at any of the sites. Audits of existing remote telemetry

units (RTU) should be undertaken to confirm spare I/O capacity in the RTU.



A key constraint pertains to the release of the instrumentation water generated, where this water

cannot be disposed of to a sewer asset. Release of water for irrigation was preferred where no

sewer disposal exists, and a site specific risk assessment will be undertaken for sites where release

to a stormwater asset is proposed.

There is the potential to realise cost savings in the delivery of two of the proposed sites (WQI 08 and

WQI 11) by combining the delivery of the WQ cabinets in conjunction with works to be undertaken as

part of the Logan East DMA work package, WP 7634.

Table E-1 provides a summary of the capital works for the proposed monitoring sites.

1. INTRODUCTION

Water utilities must not only respond to regulatory requirements, but also satisfy consumer demand for

drinking water of a consistently high quality. A water quality strategy that includes remote monitoring of the

network can provide water utilities with the ability to proactively manage the risks associated with the supply

of potable water and meet both of these business needs.

Since 2010, Logan City Council (LCC) has invested significantly in active management projects targeting

improvements in water quality. One aspect which has been identified is the significant gap in the availability

of real-time water quality data at critical points within the network. Currently, LCC relies on manual sample

collection and laboratory testing which typically takes up to a week to identify issues. This method does not

achieve appropriate response times to potentially critical events in the water network which may adversely

impact customer health, and limits the ability of operations staff to make real time adjustments to the

network.

Remote water quality monitoring can address some of these issues and provide additional benefits,

including:

early warning of changes in source water quality by monitoring specific or surrogate parameters

enhanced ability to meet increasingly strict regulatory requirements

reducing chemical dosing costs by optimizing and continuously monitoring and regulating the chemical

dosing and operational performance of the network

maintaining customer confidence by transparent reporting on the water quality within the network

1.1 Objectives

The objective of this current Task is to undertake a detailed planning investigation for the installation of

online water quality monitoring instrumentation at ten sites within the Logan water supply network.

1.2 Scope

The scope of this Task is as follows:

Undertake site visits to identify constraints/opportunities for proposed monitoring sites

Review existing infrastructure, operational feasibility (such as power and radio telemetry), site

constraints, approvals, environment, community and constructability issues

Undertake a first principles cost estimate



1.3 Business Drivers

The main Business Drivers for this study are:

improving the Levels of Service by improving the identification and response times to water quality

issues in the network (Improvement)

2. PLANNING CONTEXT

Since 2010, LCC has invested significantly in active management projects targeting improvements in water

quality. This strategy has identified a significant gap in the availability of real-time water quality data at critical

points within the network. In addition, the time-consuming nature of manual sample collection and laboratory

testing does not facilitate an appropriate response time to potentially critical events in the water network that

may adversely impact customer health, and limits the ability of operations staff to make real time adjustments

to the network.

2.1 Existing Situation

Figure 2-1 illustrates the Water Quality sampling locations currently monitored by LCC.

Figure 2-1: Current Sites Remotely Monitored by LCC

Figure 2-1 shows that the existing sites are predominantly located throughout Logan North. Monitoring sites

within Logan East at the Logan River Pump Station and Wuraga reservoir are both new monitoring sites

installed in 2013 as part of Emergent Task WP7709. Logan South, with the exception of Pub Lane Reservoir

site, has historically been monitored with manual sample collection and laboratory analysis. This manual

sampling, in conjunction future network operating arrangements, was used to identify priority locations for

online monitoring.



2.2 Previous Studies

The Logan Water Alliance (LWA) recently completed an Online Water Quality Monitoring Strategy (LWA,

2013). This report identified the need for:

Two (2) monitoring sites to control the process loop of an existing disinfectant dosing facility located

at:

o WQI03 - Spring Mountain reservoir

o WQI04 - Woodhill reservoir

Eight (8) monitoring sites to monitor areas with historical water quality issues located at:

o WQI05 - St Jude Circuit, Jimboomba

o WQI06 - Homestead Drive, Flagstone

o WQI07 - Mundoolun pump station

o WQI08 - Black Diamond Crescent, Bethania

o WQI09 - Parfrey Road, Rochedale South

o WQI010 - Logan Village

o WQI011 - Bannockburn Road, Windaroo

o WQI012 - Springwood low level reservoir.

Two further monitoring points (WQI 01 and WQI 02) were identified in the Online Water Quality Monitoring

Strategy at Travis Road Reservoir. The design of these two sampling locations was included with planned

works at the reservoir associated with construction of a new outlet main. This monitoring equipment is

currently being delivered by LWA under work package (WP) 7635 and is not included in the scope of the

current study.



Figure 2-2 illustrates the proposed online WQ sampling sites.

Figure 2-2: Proposed Sites to be Remotely Monitored by LCC

The monitoring objective for each of the proposed sites was determined through consultation with key LCC

stakeholders for the Online Water Quality Monitoring Strategy, and is outlined in Table 2-1.

WQI12 Springwood Low Level Reservoir

Reservoir Outlet Will monitor the water quality in the central areas of the Springwood Low water supply zone near the Springwood Low Level Reservoir.



The Online Water Quality Monitoring Strategy identified that the capital expenditure for these sites is

estimated at $500,000. These costs have been developed using the results of market surveys and

construction costs from recently-undertaken projects of a similar nature.

The LCC Capital Works Program includes $600,000 allocated for the proposed monitoring sites under CWP

item W0003.

2.3 Selection of Water Quality Monitoring sites

Water Quality throughout a water supply zone can vary depending on a number of factors, including

seasonal demand changes, flow reversals, storage size and distance from the supply source. To be able to

capture the changes in water quality that can occur within a zone, sampling locations can include the

following general locations:

within a reservoir

inlet and outlets of reservoirs

within the reticulation or at network extremities

within a trunk main or at a pump station

upstream and downstream of chemical dosing locations

points in the zone with a historical record of water quality incidents

The selection of a site for online monitoring was based on a combination of historical grab sample data,

consultation with operations staff, existing site infrastructure, cost and using hydraulic modelling to assist in

the decision making process where necessary.

Sites were classified either as a Critical Control Point (CCP) or Quality Control Point (QCP) in accordance

with Hazard Analysis and Critical Control Point (HACCP) categorisation of each selected site.

A CCP is a point where control can be applied that prevents, eliminates or reduces exceedances of a critical

water quality parameter incident in a timely manner; whereas a QCP is a site where only limited or no real-

time action can take place to reduce or prevent a water quality issue from occurring.



Table 2-2 outlines the HACCP classification of criticality for the monitoring sites.

3.1 Risk Assessment for disposal of instrumentation water

Potable water release to the stormwater network was highlighted as a restricted activity and is regulated by

the Environmental Protection Act 1994 (EP Act, the Act).

Section 319 of the EP Act, subsection (1) prescribes that:

'A person must not carry out any activity that causes, or is likely to cause, environmental harm unless the

person takes all reasonable and practicable measures to prevent or minimise the harm (the general

environmental duty).'

Subsection (2) outlines the measures which must be regarded as part of a persons' general environmental

duty. This includes consideration of the following:

a) the nature of the harm or potential harm

b) the sensitivity of the receiving environment

c) the current state of technical knowledge for the activity

d) the likelihood of successful application of the different measures that might be taken

e) the financial implications of the different measures as they would relate to the type of activity

A preliminary risk assessment was undertaken for the release of potable water at sites where release to

sewer was not possible. The risk assessment for the release of potable water to the stormwater network as

part of this current study considers:

the likelihood and impact to the receiving environment/s

the alternative measures that can be taken to avoid release to stormwater

the cost of these alternatives

The risk assessment is provided in Appendix A.



4. ASSUMPTIONS

This chapter outlines the various assumptions used in this study, such as the monitoring parameters, basis

for site location, site requirements and assumptions used for developing first principles cost estimates.

4.1 Water Quality Monitoring Parameters

The water quality instrumentation required for each of the priority sites was outlined in the Online Water

Quality Management Strategy. At the start up meeting for this current Task, an additional requirement to

monitor free chlorine and total chlorine at all sites was added in anticipation of the conversion of water

supplies to chlorinated supply for all of South East Queensland (currently under consideration by Seqwater

(Bulk water supply authority)). The allocation of space within the new water quality monitoring cabinets (at a

minimum) will ensure the easy integration of future instrumentation for monitoring free chlorine residual.

Additionally, this will ensure online monitoring is available to control operational and disinfection

management activities, ie breakpoint chlorination.

The adopted parameters to be measured at each site are as follows:

pH

Temperature

Free Chlorine

Total Chlorine

In addition to these four parameters, Nitrate measurement was identified as an indicator for monitoring for

nitrification episodes in the distribution network. Nitrification in chloraminated water systems can lead to

depleted disinfectant levels and consequently increased biological contamination, as a result of improved

conditions for biofilm growth within water mains. Nitrate measurement was added to two sites within Logan

North and one site in Logan South, namely:

Springwood Low Level reservoir outlet (WQI 12)

within Springwood High level water supply zone (WSZ) (WQI 09)

within Travis Road (Jimboomba) WSZ (WQI 06)

These sites will provide monitoring of nitrification levels in the bulk water supply entering the network from

Kuraby reservoir and at a point in the supply zone.



4.2 Location of Water Quality Cabinets

The location of the proposed water quality sampling cabinets was determined by assessing locations:

near existing LCC Remote Terminal Unit (RTU) sites for ease of connection to Telemetry and mains

power supply

near existing wastewater assets for ease of discharge of instrumentation water

in part of the network that is able to meet the location objectives outlined in the Online Water Quality

Management Strategy.

4.3 Water Quality Instrumentation

The selection criteria for water quality instrumentation were based upon minimising operator maintenance

and chemical reagent requirements. It was agreed among the POAR workshop attendees that where

possible, monitoring equipment not requiring reagents be preferentially adopted, as this will minimise

ongoing costs, and reduce disposal requirement and OHS handling concerns that may otherwise be

associated with reagent handling and use.

The key criteria considered for selecting the preferred equipment supplier was based on:

Cost

Ability of supplier to provide instrumentation required to monitor the designated parameters

Equipment required and resulting layout of instrumentation within cabinet

Sensor/Equipment life

Maintenance and calibration requirements

Amount of water generated requiring release.

Other criteria included the availability of a turnkey supplied cabinet that would enable installation by Logan

City Council Operations staff. A supplier shortlist was developed to meet these needs.

4.4 RTU Site Audits

Audit of the proposed sites was identified at the POAR workshop to be undertaken during detailed design, in

order to determine availability of spare I/O for connection of the WQ instrumentation to existing RTUs and

ensure that incorporation of the proposed instrumentation can be achieved at the existing site.



4.5 First Principle Cost Estimate

The following assumptions were used to develop the cost estimates for the proposed monitoring sites.

Project Management costs were developed based on the following:

o Project Duration - 5 Weeks (for the construction works and installation of eight sites)

o Project Manager, Project Engineer - 2 hour/day

o Site Supervision - 4 hours/day

Instrumentation costs were developed based on formal quote requests from instrumentation

suppliers. The instrumentation costs reflected the specific instrumentation requirements for each site

Commissioning costs have been estimated based on costs provided for similar projects



5. DETAILED PLANNING

The following section outlines specific requirements for the individual monitoring sites. A description of each

site is provided outlining specific site constraints, risks and opportunities. A cost estimate has also been

compiled for each site based on first principle cost estimates for the civil component of works, supplier

quotes, installation and commissioning of the proposed monitoring cabinets.

5.1 WQI 03 - Spring Mountain Reservoir

5.1.1 Site Description

This location was selected as a Quality Control Point at the extremity of the network and will monitor any

decline of disinfection residual within Spring Mountain reservoir. Approximately 26% of existing monthly

sample readings indicate inadequate disinfection levels (below 0.2 mg/L) as reported in laboratory sampling

data from the site (LWA, 2012). This site will be considered a Critical Control Point (CCP) should a new

chlorine booster station be installed; however, the decision to implement a booster station will be informed by

the proposed online monitoring at Spring Mountain.

The proposed monitoring point is on the combined inlet-outlet main to the reservoir. There is an existing

tapping on the main which was previously used as a rechlorination point - this tapping can be reused,

minimising the installation requirements for the sampling line. The WQ cabinet can be located adjacent to a

disused dosing building, and a conduit can be installed to provide connection to the RTU for the site, which is

located adjacent to the reservoir. Figure 5-1 shows the proposed location of the WQ cabinet while the

concept layout plan for the site is provided in Drawing 90-12-38-S-DWG-CI-2002 of Appendix B.

Figure 5-1: Proposed WQI 03 monitoring point at Spring Mountain Reservoir



5.1.2 Risks and Opportunities

Environmental/Approval constraints

A review of environmental factors has highlighted some risks for this site, as summarised in Table 5-1, while

the complete Environmental Risk Assessment in provided in Appendix C. As the site for the proposed WQ

cabinet is on already cleared land, there is no risk of disturbance to native vegetation.

Issue Comment Action

Presence of Fire Ants Site is mapped within a high risk fire ant area

Movement of restricted items in compliance with approved risk management plan (ARMP)

Bush fire Site mapped as a Medium Risk bushfire hazard area

Management required during construction

Discharge of Instrumentation Water

There is no nearby wastewater infrastructure to allow disposal of the instrumentation water. It was agreed in

discussion with LCC representatives that the preferred means of discharging the instrumentation water is via

irrigation. Section 3.1 outlines the risk assessment process undertaken for sites where no opportunity exists

to discharge the instrumentation water to a wastewater asset.

Integration with Dosing control

As the proposed monitoring site is likely to be integrated with a future dosing facility, provision should be

made for incorporating the monitoring equipment to provide a feedback control loop with the dosing system

as outlined in Figure 5-2.

Figure 5-2: Future dosing arrangement



5.1.3 Cost Estimate

Table 5-2 outlines the cost estimate for instrumentation supply, construction and integration into the existing

SCADA system by a sub-contractor. The detailed first principle cost estimate is provided in Appendix D. A

provisional sum has been designated for the installation of a sprinkler/sub-surface irrigation system should

stormwater release via soak away be deemed environmentally unacceptable. This will be subject to a risk

assessment undertaken during detailed design in conjunction with LCC prior to construction.

Indirect costs* $4,600

Total $49,000

*Includes Design and Environmental Group project management and defects liability allowance



5.2 WQI 04 - Woodhill Reservoir


This location was selected as a quality control point at the network extremity, where low disinfection levels

have previously been observed. Approximately 30% of analysed lab samples were observed to have

disinfection levels less than 0.2 mg/L (LWA, 2012). This site will be considered a Critical Control Point upon

completion of a new chlorine booster station, which is currently being installed. The proposed monitoring

equipment must be capable of integrating with future dosing equipment to provide feedback control for future

dosing.

This location will monitor chlorine residual on the outlet of Woodhill reservoir. The instrumentation cabinet

can be installed in the new pump station building. During the site investigations, the new pump set was not

installed, later being commissioned on the 17th January 20141. A new tapping is proposed at the existing

sampling location, and discharge is proposed to connect to the stormwater outlet from the reservoir site. This

will be subject to a risk assessment undertaken during detailed design in conjunction with LCC prior to

construction. Should a risk assessment determine the proposed stormwater disposal is untenable, a

subsurface irrigation system will be installed to water the grassed area at the reservoir site.

Figure 5-3 shows the existing pump station building, while the concept layout plan for the site is provided in

Drawing 90-12-38-S-DWG-CI-2004 of Appendix B. As noted, further field verification is required to determine

the WQ cabinet location within the pump station building.

1 Advice provided by LCC Water Operations





As the water quality monitoring cabinet is proposed within the existing pump station building there is no risk

of disturbance to native vegetation or public amenity with the proposed installation.


There is no nearby wastewater infrastructure to allow disposal of the instrumentation water. It was agreed

that the preferred means of discharging the instrumentation water is via the existing stormwater drain for the

reservoir site, which flow toward a stormwater drain in a nearby property. The alternative means of discharge

is subsurface or sprinkler system irrigation. Section 3.1 outlines the risk assessment process undertaken for

sites where no opportunity exists to discharge the instrumentation water to a wastewater asset.

Integration with Dosing control

As the proposed monitoring site will be integrated with a future dosing facility, provision should be made for

incorporating the monitoring equipment to provide a feedback control loop with the dosing system as outlined

in Figure 5-2. Equipment selection should specify these requirements between monitoring and future dosing

equipment.

Installation with future dosing unit

There is potential to realise cost savings by incorporating the installation of an online water quality monitoring

cabinet within the future chlorine booster station to be installed at the site.

5.3 WQI 05 - Jimboomba Reticulation


This location was selected as a quality control point within the Travis Road WSZ and will monitor disinfection

residual at the extents of this zone subject to high water age. Water sampling in the Jimboomba area of

Travis Road WSZ includes disinfection levels below 0.2 mg/L in approximately 20% of historical data from

July 2010 to December 2011 (LWA, 2012).

The proposed instrumentation cabinet will be located at the Jimboomba 6 (SPS 80) wastewater pump station

at Cerina Circuit, Jimboomba. There is an existing potable supply to the pump station from which a sample

tapping point can be installed, while discharge of the instrumentation water is to the adjacent pump station

wet well.

Figure 5-4 shows the proposed location of the WQ cabinet and existing RTU, while the concept layout plan

for the site is provided in Drawing 90-12-38-S-DWG-CI-2003 of Appendix B.

Figure 5-4: WQI 05 sample point at Jimboomba





the complete Environmental Risk Assessment is provided in Appendix C. As the site for the proposed WQ

cabinet is on already cleared land within the pump station area, there is no risk of disturbance to native

vegetation.

Potable water supply

The potable water sampling point may be sourced from the backflow prevention device pipework installed

adjacent to the RTU at the pump station, rather than from the potable water main in front of the pump station,

which will minimise pipework requirements for connection. This connection should be confirmed in

conjunction with Logan City Council Water Operations representatives.

5.4 WQI 06 - Flagstone Reticulation


This location was selected as a quality control point for monitoring the outgoing water quality from Round

Mountain reservoir within Flagstone. The water age through Round Mountain reservoir from the proposed

New Beith Road SRWP offtake will likely increase in the early years of supply to lower Logan South,

compared to the existing supply arrangement. Funds were allocated under Capital Works item W0003 -

Logan South Disinfection Project for a future dosing station at Round Mountain reservoir which will utilise

readings from the proposed water quality instrumentation in Flagstone for trim dosing purposes.

5.5 WQI 07 - Mundoolun Pump Station


This location was selected as a quality control point within the Razorback/Mundoolun WSZ. Supply to the

zone is from the South Maclean clear water tanks. Historical sample data in the July 2010 to December 2011

sample period indicates that approximately 60% of samples contained inadequate disinfection levels (LWA,

2012).

The water quality instrumentation can be installed within the Mundoolun water pump station building, utilising

a spare tapping point on the common suction main. There is sufficient space available to mount an

instrumentation cabinet on the wall adjacent to the pump set and utilise underfloor conduits back to the

switchboard and RTU for connection of power and telemetry.

Discharge of water from the instrumentation cabinet is proposed by irrigation. The land adjacent to the pump

station is currently under an infrastructure agreement between LCC and a developer - this may provide for

discharge of the instrumentation water to an adjacent public recreation space. This arrangement should be

facilitated with Logan City Council Development Assessment Services. A decision will also be required in

determining asset maintenance responsibilities within Council.


for the site is provided in Drawing 90-12-38-S-DWG-CI-2007 of Appendix B. Note that the discharge line

shown in this figure is based on the assumption that a tank for storing water for irrigation purposes is

installed in front of the pump station, between the vehicle roller door and entry door on the western side of

the building. The exact siting and feasibility of tank location can only be determined following further

negotiation with the developer at a later date.

Figure 5-6: WQI 07 Cabinet Location, Mundoolun Pump Station




A review of environmental factors has highlighted that the site is located within a high risk fire ant area, with

the appropriate measures for notification of Biosecurity Queensland to be undertaken in conjunction with the

subcontractors' Approved Risk Management Plan (ARMP). The complete Environmental Risk Assessment in

provided in Appendix C.


There is no nearby wastewater infrastructure to allow disposal of the instrumentation water. The only location

available for discharging this instrumentation water is the adjacent developer held land. There may be

opportunity for further negotiation with the developer to allow for discharge to the adjacent land for

irrigation/watering purposes. Should no arrangement be forthcoming, investigation must be made into the

release to a sub-surface soak away pit, as there is no planted vegetation at the site which can be irrigated.

This will be subject to a risk assessment undertaken during detailed design in conjunction with LCC prior to

construction.

Connection of sampling point with suction pipework

It was assumed that the water sampling point can be connected to a blanked off tapping on the common

suction main of the pump sets. Detailed design should confirm that no excess positive/negative pressures

are imparted on the sensor equipment, which are limited to 0.5 bar (50 kPa). Pressure head is typically

broken within the flow assembly which houses the sensor; however, the proposed arrangement should be

confirmed with the equipment manufacturer at detailed design.

5.6 WQI 08 - Bethania Reticulation


This location was selected as a quality control point at the extent of the Logan East WSZ. This location will

monitor chlorine residual downstream of Woodhill reservoir. This site will be established in conjunction with a

proposed District Metered Area (DMA 58), which is part of LWA Work Package 7634 - Logan East Water

Supply DMA Management and Fire Flow Augmentations. This work package is currently in detail design with

construction scheduled to commence in January 2014.

The water quality instrumentation is proposed to be installed in a combined control cabinet with the PRV

instrumentation. The cabinet location will be confirmed as part of the design for work package 7634. A

sample line is proposed from within the PRV pit, and there is an adjacent sewer manhole for discharging the

instrumentation water. Mains power supply will be sourced from a street pole in Black Diamond Crescent.

Figure 5-7 shows the proposed location of the WQ cabinet, PRV pit and RTU, while Drawing 7634-004-W-

DWG-CI-2050 REV D in Appendix B shows the concept layout plan for this site.

Figure 5-7: PRV/WQI 08 Cabinet location at Bethania


An Environmental and Approval assessment has identified minimal risks for construction. The proposed

installation is in already cleared land. The identified risks are outlined in Table 5-9.





Presence of Groundwater The site is at low elevation (10m AHD) and is located near Logan River

Groundwater is to be captured and tested prior to disposal

Presence of Fire Ants Site is mapped within a low risk fire ant area




PRV pit and Cabinet location

Detailed design should ensure that the PRV pit location is such that conduit lengths can be minimised where

possible. In addition, the adjacent property contains a pool and the cabinet should be located in a position

such that the cabinet cannot be used to gain access to the fenced pool area. Discussions should also be

progressed with the property owner regarding the final location of the cabinet.

5.6.3 Cost Estimate

Table 5-10 outlines the cost estimate for supplier instrumentation and supply, construction and integration

into the existing water supply network. Cost efficiencies can be obtained if the WQ equipment is installed in

conjunction with the PRV site, given there will be minimal additional cost for the installation of WQ equipment

(the only additional scope item being the discharge line for instrumentation water).

As such, costing for this item is presented with and without project delivery in conjunction with work package

WP7634 (Logan East DMA sites), demonstrating the potential cost savings if delivered under the TOC

budget for work package 7634. Note that there would be a minor variation to the WP7634 TOC to

accommodate this additional scope.

5.7 WQI 09 - Springwood High Level Water Supply Zone


This location was selected as a quality control point within the Springwood High Level Water Supply Zone to

monitor the decay in disinfection residual between this location and water supplied from Springwood Low

Level Reservoir. This location will monitor disinfection residual as well as Nitrate, which will serve as an

indicator for nitrification occurring in the network.

The proposed cabinet location is alongside the existing PRV installation at Parfrey Road, Rochedale

(opposite Gills Close). A sample point tapping is proposed on the DN250 supply main to the PRV zones

(DMA14 and DMA15), while power and telemetry can be supplied from the PRV cabinets. A stormwater gully

inlet pit is available to discharge the instrumentation water; however, if this arrangement is untenable the

discharge line can be directed across the road into the nearest sewer manhole (at front of 23 Parfrey Road).



Figure 5-8: WQI 09 cabinet location at Parfrey Road, Rochedale


Environmental and Approvals Assessment

The risk assessment undertaken for the site has identified the following risks, as outlined in Table 5-11.










There is no adjacent sewerage infrastructure to allow disposal of the instrumentation water. It was agreed in

discussion with LCC representatives that the preferred means of discharging the instrumentation water is to

the stormwater drain, which will minimise site installation costs resulting from traffic management and road

crossings. If this is not tenable, the discharge line can be directed to the sewer manhole at the front of the

opposite property at 23 Parfrey Road.

5.8 WQI 10 - Logan Village Reticulation


This location was selected as a quality control point at the extent of the Travis Road Reservoir WSZ in Logan

Village. Disinfection residuals within the Logan Village area were found to be the worst in Logan South, with

approximately 74% of monthly disinfection grab samples in the July 2010 - December 2011 sample period

containing inadequate levels of disinfection (levels below 0.2 mg/L). A new dosing facility is currently being

designed as part of the Work Package 7635 Travis Road Reservoir outlet main which will see an

improvement in the disinfection residuals in Logan Village.

The proposed water quality monitoring instrumentation location is adjacent to the Logan Village 1 (SPS 70)

wastewater pump station. A new potable supply is required at the pump station (none currently available),

which will improve facilities at the pump station for cleaning/pump maintenance, and will also provide a

sample water source.

The existing RTU is installed on a raised platform above the Q100 flood level, hence the WQ cabinet has

been proposed on the existing platform. A preliminary assessment of the platform has confirmed the WQ

cabinet can be located on the platform in at least two locations adjacent to the existing RTU; however,

should be confirmed during detailed design when exact cabinet dimensions and constraints are known.

The environmental risk assessment undertaken for the site has identified the following risks, as outlined in

Table 5-13.



Presence of Fire Ants Site is mapped within a low risk fire ant area




Installation of Cabinet on existing raised RTU platform

A preliminary assessment of the raised platform suggests that sufficient space is available for the installation

of the WQ cabinet. Provision has been made in the cost estimate for the modification (if necessary) of the

raised platform should there be insufficient space; alternatively, the WQ cabinet could be located adjacent to

the existing platform on a new cabinet stand if the cabinet cannot be co-located on the existing platform.

5.9 WQI 11 - Windaroo Reticulation


This location was selected as a quality control point at the extremity of the Logan East network. The site is

proposed as part of a new DMA installation (DMA 62) at Bannockburn Road, Belivah. A combined PRV and

WQ cabinet is proposed for the site in the road reserve in Bannockburn Road. Power supply will be subject

to Energex approval, while new telemetry will be installed for the PRV.

Instrumentation water can be released into the gravity sewer main which runs parallel to the proposed PRV

installation. Figure 5-10 shows the proposed location of the WQ cabinet and existing RTU, while the concept

layout plan for the site is provided in Drawing 7634-005-W-DWG-CI-2020-REV G of Appendix B.

Risk of Vehicular Collision

The PRV installation is located adjacent to the roadway, and is therefore at risk of collision from vehicles.

Detailed design should seek to maximise the distance from the roadway. It may be feasible to locate the

PRV/WQ RTU cabinet behind the adjacent power pole. This will be determined in conjunction with necessary

clearances as required by the electricity provider. In addition bollards can also be considered in the cabinet

design to reduce damage from collision.

5.9.3 Cost Estimate

Table 5-16 outlines the cost estimate for supplier instrumentation and supply, construction and integration

into the existing water supply network. Cost efficiencies can be obtained if the WQ equipment is installed in

conjunction with the PRV site, given there will be minimal additional cost for the installation of WQ

equipment.

As such, costing for this item is presented with and without project delivery in conjunction with work package

WP7634 (Logan East DMA sites), demonstrating the potential cost savings if delivered under the TOC

budget for work package 7634. Note that there would be a minor variation to the WP7634 TOC to

5.10 WQI 12 - Springwood Low Level Reservoir


This location was selected as a quality control point at the outlet from Springwood Low Level Reservoir. This

site will be monitored in conjunction with the WQI 09 site in Rochedale, specifically monitoring for residual

decay in the Springwood High Level Zone (HLZ). The proposed sampling point is on the DN600 outlet of the

reservoir, which, in addition to comparing residual decay between Springwood Low Level zone and

Springwood HLZ, will also enable comparison with the upstream monitoring point at Compton Road.

There is existing telemetry at the reservoir site located within the Springwood Low Level Pump Station. The

WQ cabinet should be located near the outlet main as indicated in Figure 5-11 to minimise sample line

length. This will require laying approximately 60-70m of buried conduit to provide power and telemetry to the

cabinet.

Figure 5-11 shows the proposed location of the WQ cabinet, while the concept layout plan for the site is

provided in Drawing 90-12-38-S-DWG-CI-2001 of Appendix B.

Figure 5-11: WQI 12 cabinet location at Springwood Low Level Reservoir




The review of environmental factors has highlighted some risks for this site, as presented in Table 5-17,

while the complete Environmental Risk Assessment is provided in Appendix C. As the site for the proposed

WQ cabinet is on already cleared land, there is no risk of disturbance to native vegetation.





Bush fire Site mapped as a Medium Risk bushfire hazard area

Management required during construction

Steep Slopes Site is adjacent to a steep slope area To be considered and managed during design and construction


There is no nearby wastewater infrastructure to allow disposal of the instrumentation water. It was agreed in

discussion with LCC representatives that the preferred means of discharge is via the existing stormwater

outlet from the reservoir site. Section 3.1 outlines the risk assessment process undertaken for sites where no

opportunity exists to discharge the instrumentation water to a wastewater asset. This arrangement will be

subject to a risk assessment required during detailed design in conjunction with LCC prior to construction.

Bushfire Hazard

The site is directly adjacent to a medium hazard bushfire area. The proposed location of the WQ cabinet

exposes the cabinet to risk of equipment loss in the event of bushfire. Remedial measures include providing

additional fire protection for the cabinet, and where possible locating the cabinet closer to the reservoir wall.

This should be further investigated during detailed design.

Future Reservoir integration

The Springwood Low Level Reservoir is comprised of two separate sections, one of which is currently offline.

The location of the proposed sampling point should ensure (where feasible) that provision is made for

sampling the second reservoir compartment when brought back online in the future.

6. CONCLUSION

This detailed planning study outlines the site specific requirements for the installation of ten additional water

quality sites throughout the Logan District. The requirements are based on a preliminary site assessment for

the proposed cabinet locations, and an assessment of the environmental, cultural heritage and approvals

requirements for each of the sites. An estimated cost to install the monitoring equipment at each site has

been developed from first principle cost estimates.

The proposed monitoring sites will serve to improve the real time management of the water supply network,

further enabling a proactive response to issues related to changes in water quality, rather than relying on

manual sampling and laboratory testing. The real-time monitoring will also enhance LCC's ability to respond

rapidly to events which may adversely affect customer health.

This detailed planning study has determined that:

There are minimal constraints for the installation of the water quality monitoring cabinets at each of

the proposed sites. There are no environmental ‘show stoppers’ or town planning approval issues

which would prevent installation of the WQ cabinets at any of the sites.

Audits of existing RTUs should be undertaken to confirm spare I/O capacity in each existing RTU

The release of the instrumentation water cannot be disposed of to a sewer asset at all proposed

sites. Release of water for irrigation was preferred where no sewer disposal exists, and a site

specific risk assessment will need to be undertaken during detailed design for sites where release to

a stormwater asset is proposed. Where the residual risk of disposal to stormwater is considered low

with no risk to the receiving environment as a result of chlorine residual, and the cost of alternative

release is prohibitive, it is recommended that disposal to the stormwater assets should proceed as

outlined in Table 6-1.

WQI 04 Woodhill Reservoir Irrigation

WQI 07 Mundoolun Water Pump Station Irrigation

WQI 09 DMA 14/15 PRV site Stormwater drain

There is the potential to realise cost savings in the delivery of two of the proposed sites (WQI 08 and

WQI 11) by combining the delivery of the WQ cabinets in conjunction with works to be undertaken as

part of the Logan East DMA work package, WP 7634.

Local Government Act 2009

Should construction access, or a lay down area be required for the proposed works, approval for temporary use of the site from LCC would be required as owner of the properties. Where this is required, a simple consent application would be lodged with the LCC Property Team. Conditions of approval would likely relate to safety, maintenance and revegetation requirements.LCC Consent required.

As Logan City Council are trustee of the lots, they have the rights to issue approval for temporary use of the site for construction access and/or lay down areas. Where this is required, a simple consent application would be lodged with the LCC Property Team. Conditions of approval are likely to relate to safety, maintenance and revegetation requirements LCC Consent required.

Any construction works or geotechnical investigations within the reserve will require prior approval from the LCC Roads and Infrastructure Branch.

Council can provide ‘in principle’ approval for the pipe alignment based on preliminary design drawings. However Council will not provide final construction approval until the final set of design drawings are available and the construction sub‐contractor has been appointed.

The sub‐contractor will then lodge an excavation and/or road closure application to Council for the works. This process is normally undertaken by the sub‐contractor and would typically form part of their scope of works. If not, the LWA Approvals team can lodge these applications.

It is important to note that any excavation works within the road reserve, regardless of whether the surfaceis sealed or not sealed, will require a Road Excavation Permit. One week should be allowed for this approval. In Principal approval and Final Construction approval required from LCC Roads and Infrastructure Branch.Road excavation permit and Road Closure Permit required from Logan City Council.

In principal approval will need to be obtained from DTMR for the proposal within State‐controlled Road. Closer to construction commencing, a pre‐start meeting will need to be held on site with DTMR where the IFC drawings, SQE report and EMP for the project must be provided. Provided DTMR have no objection to these documents, a Works Permit will be issued, allowing construction to begin. If there will be no impacts to traffic flow on the state controlled road, a pre start meeting and Works Permit may not be required from DTMR. DTMR In principle application required (also obtain consent from existing infrastructure providers in

road reserve area ‐ i.e. Energex, Telstra)

DTMR Works permit required.

MINUTES

NUMBER: ITEM:

1 WQI 03 – Spring Mountain Reservoir No comments regarding proposed location or discharge options.

2.

WQI 04 – Woodhill Reservoir Sites proposed for booster chlorination station as part of the Logan South Disinfection Strategy. Design/location of the proposed WQ monitoring equipment should ensure this is in conjunction with the proposed chlorination booster stations (CPM).

3

WQI 05 – Jimboomba 6 SPS LB noted supply from Round Mountain along the PEET main into Flagstone is pending commissioning of this main.

Meeting Minutes

7600-000-P-MOM-PL-8229


Action: CPM to confirm whether both WQI 05 and WQI 06 are required for WQ monitoring, given the proximity of these two sites.

4

WQI 06 – Flagstone 2 SPS No comments regarding proposed location or discharge options. Action: As noted in item 3.

5

WQI 07 – Mundoolun Road WPS Site is proposed for booster chlorination station as part of the Logan South Disinfection Strategy. Design/location of the proposed WQ monitoring equipment should ensure this is in conjunction with the proposed chlorination booster stations (CPM).

6 WQI 08 – DMA 58, Bethania No comments regarding proposed location or discharge options.

7 WQI 09 – DMA 14/15, Rochedale No comments regarding proposed location or discharge options.

8.

WQI 10 – Logan Village 2 SPS RP queried whether there was an alternative location for the monitoring point which may be in a location with poorer water turnover. The current location (adjacent to the LV2 SPS) has good turnover due to the industrial demand in the area. Action: SH to investigate alternative location

9.

WQI 11 – DMA 62, Belivah

LB queried whether this site is a duplicate of the existing monitoring location in the area. The map below shows the general location of the existing monitoring point, LB to confirm exact location.

It appears that the existing monitoring location will provide representative sample of water quality in the network. The existing site should be visited to confirm whether Total Chlorine monitoring can be included in future in the existing cabinet.

Action: CPM to confirm that the existing monitoring location is maintained, and the proposed WQI 11 site be dropped from the list. Provision for future upgrade of this site to monitor Total Chlorine can be considered.

10.

Discharge to stormwater

During discussion of sites where alternative disposal (disposal to stormwater) is considered it was agreed that LWA environmental team can help undertake a risk assessment in the fulfilment of any EHP/General Environmental Duty requirements.

Action: SH to liaise with environmental team to arrange contribution to risk assessment

11.

Equipment

CPM queried ongoing maintenance requirements in the selection of equipment for nitrate monitoring. CPM noted ion selective electrodes for nitrate monitoring were previously subject to high maintenance costs on a regular ongoing basis.

Action: SH to confirm with suppliers

12.

Communications

RB queried acceptability of MODBUS communication protocol of proposed instrumentation.

Action: PB to confirm suitability/acceptance

13.

Telemetry

It was noted site audits of spare RTU I/O be undertaken for the proposed WQ monitoring sites.

Action: RB to engage LWA electrical design engineer/liaise with PB

14. Cost Estimates

It was noted that site costs for the sites adjacent to proposed DMA sites (WQI 08, WQI 11) be included in the site costing.

Meeting Minutes

7600-000-P-MOM-PL-8229


Action: SH to include these site costs (noting inclusion/exclusion of WQI 11 site to be confirmed)

15.

Equipment suppliers

It was agreed by stakeholders that E+H be engaged to supply instrumentation given: - E+H instrumentation preferred by Operations - E+H instrumentation offered at lowest cost - E+H can provide instrumentation to monitor all of the desired parameters Action: LWA design engineer to liaise with E+H to develop instrumentation layout within cabinet
