The following members constitute the nineteenth Public Works Committee as reconstituted on 6 May 2014: Mrs Annabel Digance MP (Presiding Member) Hon Paul Caica MP Ms Dana Wortley MP Mr Michael Pengilly MP Mr Tim Whetstone MP Staff assisting the Committee: Executive Officer: Ms Alison Meeks Administrative Officer: Mr Ryan-Lee Piekarski THE FUNCTIONS OF THE COMMITTEE Section 12C of the Parliamentary Committees Act 1991 defines the functions of the Public Works Committee as: (a) (b) to inquire into and report on any public work referred to it by or under this Act, including(i) the stated purpose of the work; (ii) the necessity or advisability of constructing it; (iii) where the work purports to be of a revenue-producing character, the revenue that it might reasonably be expected to produce; (iv) the present and prospective public value of the work; (v) the recurrent or whole-of-life costs associated with the work, including costs arising out of financial arrangements; (vi) the estimated net effect on the Consolidated Account or the funds of a statutory authority of the construction and proposed use of the work; (vii) the efficiency and progress of construction of the work and the reasons for any expenditure beyond the estimated costs of its construction; to perform such other functions as are imposed on the Committee under this or any other Act or by resolution of both Houses. Public Works Committee 2 Victor Harbor Wastewater Network Upgrade Project PART ONE: PREAMBLE AND PROJECT BACKGROUND 1.1 Term of Reference Parliamentary Committees Parliamentary Committees have the specific task of examining individual initiatives, projects or policies of the government of the day, or issues of importance to society as a whole. Standing Committees are created by an Act of Parliament and charged with the ongoing examination of subject categories such as public works. Parliamentary Committees are made up of both government and opposition members, with numbers of each calculated according to rules which reflect the numbers of seats each group holds in the Parliament. Much of the Committee process is open to the public and completed reports are public documents. This Project SA Water has referred the Victor Harbor Wastewater Network Upgrade Project to the Public Works Committee pursuant to the requirements of the Parliamentary Committees Act 1991. Please refer to the "Functions of the Committee" on the previous page for a full description of the Committee's tasks. 1.2 Further Reporting to the Committee SA Water must notify the Committee immediately in writing should there be substantial changes to the nature of the project or the evidence provided to the Committee. To enable appropriate monitoring of the project, SA Water must also provide quarterly reports to the Committee on the progress of construction. Pursuant to section 12C (vii) of the Act, these reports must outline the efficiency and progress of construction and provide an explanation of any expenditure beyond the estimated costs quoted in this report. Evidence of any substantial changes to, or the withdrawal of, any approval (provisional or otherwise) must also be relayed to the Committee immediately with an appropriate explanation, and an assessment of the probability of a suitable resolution. In addition, the Committee requires that it be notified of the proposed date for the commissioning of the works. The Committee has the authority under Section 16 (1)(c) of the Parliamentary Committees Act 1991 to re-open investigations into any project for the purpose of further examination and monitoring. 1.3 Scope of This Report This report examines the history of the proposal and the efficacy of the application of South Australian taxpayer funds to the Victor Harbor Wastewater Network Upgrade Project. The report structure is guided by, and largely limited to, the terms of the Parliamentary Committees Act 1991. It describes, in summary, the evidence presented to the Committee and concludes with a brief summary incorporating findings and recommendations. Detailed evidence upon which the Committee’s decision is based is held in Parliament and, in most cases, can be examined by making an application to the Committee Administrative Officer. Public Works Committee 3 Victor Harbor Wastewater Network Upgrade Project 1.4 Project Background The Victor Harbor wastewater scheme serves a population in excess of 14,000 permanent residents (Australian Bureau of Statistics, 2014). This can increase fifty to one hundred percent during holiday periods. Sections of the Victor Harbor Wastewater Network are currently operating near or at capacity, and with the proposed residential expansions and new Fleurieu Regional Aquatic and Health Centre (FRAC) there is a need to expand the networks capacity. There is a risk of wastewater overflows with the current network. Modelling of the network shows that overflows would likely occur at the low point in the network immediately adjacent to the Hindmarsh River mouth. In addition, new development is occurring throughout the Victor Harbour Wastewater Network catchment area, including residential development and the FRAC which is due for completion in December 2016. Several other large areas in the north of the Victor Harbor area have been rezoned for urban development. Augmentation changes have been collected since 2007 and there are agreements in place for the wastewater from the FRAC to be treated at the wastewater treatment plant. Hence there is a need to upgrade the wastewater treatment network capacity to manage the additional wastewater. There is also an expectation from the community that, given the collection of augmentation charges over the years, the wastewater network and treatment plant will be upgraded and expanded as and when required. Public Works Committee 4 Victor Harbor Wastewater Network Upgrade Project PART TWO: EXECUTIVE SUMMARY The Victor Harbor Wastewater Network is at capacity. In order to address this and the expansion in the region, SA Water is proposing to upgrade the wastewater treatment network to accommodate the additional wastewater flows at a cost of $7.289 million (GST exclusive). The works will include the installation of approximately 6.2 kilometres of gravity and rising wastewater mains pipeline and the construction of three new wastewater pump stations. The project also includes the decommissioning of any superfluous wastewater pump stations. This new network will provide services to the new FRAC and the proposed residential developments. Augmentation charges have been collected since 2007 in anticipation of the need to upgrade and/or expand the wastewater network to accommodate the growth in the region. The project will ensure an adequate capacity for wastewater flows to 2030, and allow SA Water to continue to meet its licensing obligations and other regulatory requirements. The construction works for the project are due to commence in April 2016 with completion later in the year. Public Works Committee 5 Victor Harbor Wastewater Network Upgrade Project PART THREE: PROJECT PROPOSAL AND PRE-CONSTRUCTION ASSESSMENTS 3.1 The Current Proposal The aim of the project is to provide the necessary infrastructure for SA Water to meet its current needs, as the network is at capacity, and to accept future wastewater from the FRAC and new developments in the Victor Harbor area. This will ensure SA Water continues to meet its licence obligations and other regulatory requirements as specified in the Code of Practice for Wastewater Overflow Management. The proposed upgrade works will provide sufficient capacity to transfer the increasing quantity of wastewater from new developments to the existing Victor Harbor Wastewater Treatment Plant, providing adequate capacity for the area to 2030. The works to be undertaken are: the installation of approximately 6.2 kilometres of gravity and rising wastewater mains pipeline, the construction of three associated wastewater pump stations, and the decommissioning of superfluous wastewater pump stations. The proposed works are in line with SA Water’s 2006 Master Plan for the area. Attachment 1 shows the proposed alignment for the project. SA Water confirmed that the current treatment plant has the capacity to manage the additional wastewater to be transported by the expanded wastewater network. The Committee sought clarification regarding the reuse and quality of treated wastewater from the treatment plant, and would like to see as much as possible of the treated wastewater being reused on ovals, parks, etc and not discharged to the Inman River or the ocean. The Committee raised concerns regarding the treated wastewater entering the Inman River from time to time, and in particular the odour that is associated with this. They requested that this issue be considered as part of the project. Risk Management SA Water reviewed the project using the Business Risk Management Policy and Framework, which requires the identification of risks, their likely impact and severity, and proposed risk mitigation strategies1. The extreme and high ranked identified risks are all form part of the “Base Case” option which is not being pursued. They were: adverse impact on SA Water reputation because SA Water would be seen as not supportive of local development downstream, and network exceeding its capacity with the potential to cause wastewater overflow incidents. These risks will be mitigated as part of the upgrade. Land Acquisition There are a number of land acquisitions required for the project, from Alexandrina Council, Hickinbotham and a private landholder. Discussions are still underway with the private landholder and an alternative alignment could be implemented should the discussion not be successful. 1 The policy and framework is consistent with the Australia/New Zealand Risk Management Standard AS/NZS ISO 4360. Public Works Committee 6 Victor Harbor Wastewater Network Upgrade Project 3.2 Consultation SA Water informed the Committee that it is committed to ensuring high levels of stakeholder engagement in order to manage expectation, concerns and any other stakeholder issues associated with the project. It has developed a community and stakeholder engagement plan to address the various project related matters raised through the stakeholder engagement process during both the development and design, and that may be raised during the construction phases of this project. Consultation has already commenced with key state government departments, as well as the City of Victor Harbor and Alexandrina Council. Local residents along the proposed route, including the Encounter Lutheran College, have already been consulted. This identified one neighbour with a new baby – a strategy is being prepared to best address the noise and possible dust impacts, including the possibility of relocation for a short period during the drilling. Letters are due to be sent to the local Members of Parliament from the Minister for Water and the River Murray. 3.3 Aboriginal Heritage SA Water engaged EBS Heritage to undertake a cultural heritage desktop assessment for the project. It included a search of the Central Archive managed by Aboriginal Affairs and Reconciliation in the Department of State Development, as well as a review of other relevant historical and archival information. No registered or recorded heritage sites were identified within a 10 kilometre radius of the current project area In considering the alignment options, Option 1 provides the least risk of encountering Aboriginal heritage as the proposed works are primarily to be undertaken on already disturbed or excavated land. However, the section of works through the Hickinbotham land, parallel to the Hindmarsh River, presents the greatest potential of finding Aboriginal heritage. SA Water is seeking to engage with the Ngarrindjeri people on the project. The Design and Construct contractor will be required to comply with SA Water’s Standard Operating Procedure for the Discovery of Aboriginal Sites during the construction work in the unlikely event heritage is uncovered. Site construction employees will be inducted into the requirements of this procedure. 3.4 Heritage Buildings A heritage assessment was undertaken for the project site. No heritage sites were identified within the project site and works area. 3.5 Ecological Sustainability SA Water’s environmental policy embraces the following principles: everything is connected, the environment has physical limits, water is a limited resource, climate change effects, pollution should be prevented wherever possible, and environmental management requires a systematic approach. As part of the contract requirements, the Design and Construct contractor is to develop processes that include sustainability aspects such as the conservation and efficient use of resources and raw materials, energy efficiency, generation and/or use of renewable energy, development of flexible Public Works Committee 7 Victor Harbor Wastewater Network Upgrade Project processes and products, design of closed loop processes where possible and where not, the implementation of recycling and reuse to reduce waste, operating within the carrying capacity of natural systems, providing a safe and healthy work environment, enhancing or not detracting from the amenity of the area, and cost effective delivery. The contractor will also need to quantify and report greenhouse emissions associated with the project. A preliminary environmental impact and cultural heritage assessment has been undertaken (see attachment 2). The Design and Construct contractor will be required to prepare an environmental management plan that addresses the site specific environmental issues such as noise, dust, erosion and stormwater management as well as any environmental conditions associated with approvals. Public Works Committee 8 Victor Harbor Wastewater Network Upgrade Project PART FOUR: JUSTIFICATION AND IMPACT OF THE PROJECT 4.1 Project Justification This project will address the key issues of potential environmental incidents caused by overflows. It will also remove significant risks such as the ability of the system to cope with the additional connection of new developments to the wastewater network as they arise. In determining the project works, three options were considered in addition to the Base Case (do nothing). Base Case: business as usual (do nothing) The Base Case consists of not upgrading the wastewater network. This will prevent immediate and future local development in Victor Harbor, specifically preventing the FRAC from opening. This is not considered viable. In collecting connection and augmentation charges, SA Water has been preparing financially for the changes to the proposed wastewater network. SA Water has also already collected augmentation charges from other developers for the proposed wastewater network upgrade. The associated reputation and wastewater overflow risks are extreme and high respectively. This would lead to a loss of confidence in SA Water, both by the state government and the general public. Three Options Three options, based on three pipeline alignments, were identified for the upgrade. The first 3.47 kilometre and the last 0.8 kilometre of the pipeline (referred to as the “common pipeline alignments”) and the pump station adjacent to the proposed FRAC are common for all the three options. (refer to Appendix A- Location plan). The difference between the proposed options are the location of the wastewater mains and two additional pump stations. The three options have been identified based on the following key criteria: Option 1 (preferred option) - the route that follows the road reserves as much as possible and therefore requires the least amount of new easements, Option 3 - the shortest route with the majority of the pipeline located on private land, and Option 2 - an alignment that is a compromise of the first two criteria. Option 1 consists of laying the majority of the gravity and rising mains along road reserves as compared to the other two options. Approximately 1.4 kilometres will be laid on private land resulting in a large amount of easements being required for Options 2 and 3, including in some previously undisturbed ground resulting in a higher risk of poor ground conditions and rock, and Aboriginal heritage impacts. Option 1 is the most economical and beneficial solution amongst the three options, addressing the current risks and achieving the project outcome for the customers. The Base Case does not meet the aims of the project and hence a “do nothing’ option is not considered feasible. The preferred option, Option 1 is the most viable considering cost, alignment, and impact on landholders, and is therefore recommended Public Works Committee 9 Victor Harbor Wastewater Network Upgrade Project 4.2 Public Value of the Proposed Project Benefits that will be achieved by this project include: supporting the development in the Victor Harbour area, thus allowing continued growth and prosperity of the region, and supporting the liveability in the region by continuing to provide essential services that change rapidly with events such as Schoolies and the holiday seasons. The proposed works align with the state government’s strategic priority “Safe Communities, Healthy Neighbourhoods” and the following South Australia’s Strategic Plan (SASP) Targets: Target 32. Customer and Client satisfaction with government services: Increase the satisfaction of South Australians with government services by 10% by 2014, maintaining or exceeding that level of satisfaction thereafter. Target 56. Strategic infrastructure: Ensure that the provision of key economic and social infrastructure accommodates population growth. The project supports these SASP targets by providing a critical wastewater network infrastructure as required by the current and growing population of the region, and reduces the environmental risk of overflow into the Hindmarsh River community area near the river mouth. 4.3 Revenue Earning Capacity of Proposed Project Revenue will be collected from new customers, both residents and businesses, who choose to connect to the new wastewater network. Charges will be in-line with those charged to other customers in the region. 4.4 Whole Life Costs of the Project The project requires capital expenditure of up to $7.289 million in nominal dollars (excluding GST). It is provided for within SA Water’s forward estimates from the Networks Extension annual program. The project will therefore have no impact on SA Water’s overall capital plan, borrowings, contribution to government or customer prices, nor will it adversely impact the outcomes of this program. To support the future expansion and upgrade of infrastructure in the region, there has been an augmentation charge set for the Victor Harbor wastewater catchment since 2007. As such, there is an expectation that the infrastructure will be upgraded and expanded as required. Also, SA Water has committed to accepting the flows from the FRAC development and other growth areas in Victor Harbour and hence committed to providing this infrastructure. There is approximately up to $100,000 operating funding associated with additional maintenance (75% of operating expenditure) and power consumption (25% of operating expenditure) required as a result of this project. The increase in operating costs will be managed within SA Water’s current operating budget. 4.5 Estimated Net Effect of the Work, and Its Use, on Public Funds A financial analysis of the project has been undertaken by SA Water, in accordance with Treasury Instructions and corporation guidelines. The analysis is based on a 30-year study period and uses a cost of capital (discount rate) of 5.06% (real, pre-tax), which is SA Water’s regulatory weighted average cost of capital as determined by the Essential Services Commission of South Australia (ESCOSA) for the current regulatory period. Options 1, 2 and 3 were compared against the Base Case to determine the best net present value (NPV). The analysis is shown below. Public Works Committee 10 Victor Harbor Wastewater Network Upgrade Project Base Case Option 1 Option 2 Option 3 30 years 30 years 30 years 30 years Total capital expenditure ($k) 0 6,761 7,030 6,984 Total residual value ($k) 0 1,143 1,188 1,181 Total revenue ($k) 0 12,369 12,369 12,369 799 1,476 1,476 1,476 (799) 5,274 5,051 5,089 n/a 6,073 5,850 5,888 4 1 3 2 Review period (years) Total operating expenditure ($k) Total NPV ($k) NPV incremental to Base Case ($k) NPV ranking Notes: 1. Operating expenditure for Base Case includes projected clean-up costs, should an overflow occur. 2. Capital expenditure excludes sunk costs of $130 000 for project development work. 3. All numbers are in discounted real dollars. Option 1 (preferred selected option) has the lowest capital cost and the highest NPV and overall ranking compared to the other options. It has a substantially lower risks for pre-construction (easement acquisitions and Aboriginal heritage approvals) and construction activities (adverse environmental damage and impact on Aboriginal heritage) compared to Options 2 and 3. Therefore Option 1 is preferred taking into account the identified risks and the marginal difference in the financial NPV results. Sensitivity testing was applied to the discount rate (plus-minus 2%). This did not change the ranking. 4.6 Project Delivery The project is due to commence construction in April 2016, with completion by the end of the year. The timeframes are outlined below. Full Financial Approval February 2016 Major Order Placed March 2016 Start Major Work April 2016 Practical Completion November 2016 Final Completion/End Defects Period November 2017 Project Operational Handover/ Closeout December 2017 The project received endorsement from the SA Water Board in December 2015 and from the Minister for Water and the River Murray in January 2016. This project is being managed in accordance with the SA Waters’ Corporate Project Management Methodology by a senior project manager from SA Water’s Infrastructure Management Group. The senior project manager is responsible for the development and delivery of the overall project including seeking the necessary approvals and management of the selected contractor/works. Public Works Committee 11 Victor Harbor Wastewater Network Upgrade Project To ensure greater certainty around the timing and cost, the project will be delivered via a two-stage procurement process with an initial Early Contractor Involvement (ECI) contract (Stage 1) followed by a Design and Construct contract (Stage 2). The ECI contractor will be selected for the Stage 1 contract phase based on their proven capability and demonstrated relevant experience to deliver this project, develop the project scope and undertake 90 percent of the design and specification enabling a robust target outturn cost to be prepared to inform the full financial approval process. The successful ECI contractor will be required to submit the following construction management plans prior to starting construction: project management plan, traffic management plan, environmental management plan, work, health and safety (WHS) management plan, quality management plan, and communication and stakeholder management plans. SA Water is aware of the Industry Participation Policy administered by the Industry Capability Network SA, a division of the Department of State Development. They have committed to comply with the policy. It is anticipated that fourteen to twenty jobs will be created for the duration of the project. 4.7 The Efficiency and Progress of the Project and Justification of Any Expenditure Beyond Estimated Costs The Committee will monitor the progress of the Victor Harbor Wastewater Network Upgrade Project as required by the Parliamentary Committees Act 1991 through the regular reports SA Water is required to provide prior to the completion of construction (refer to "Further Reporting to the Committee"). The Committee will provide a further statement to Parliament in the event that subsequent information provided renders this report inaccurate or misleading. Public Works Committee 12 Victor Harbor Wastewater Network Upgrade Project PART FIVE: CONCLUSION & RECOMMENDATION The Public Works Committee has examined written and oral evidence in relation to the Victor Harbor Wastewater Network Upgrade Project. It has also been assured by SA Water officials that acquittals have been received from the Department of Treasury and Finance, Premier and Cabinet and the Crown Solicitor that the works and procedures are lawful. The Committee is satisfied that the proposal has been subject to the appropriate agency consultation and meets the criteria for examination of projects as set out in the Parliamentary Committees Act 1991. Based upon the evidence considered, and pursuant to Section 12C of the Parliamentary Committees Act 1991, the Public Works Committee reports to Parliament that it recommends the proposed public work.

Assessment Report and Project Environmental Management Plan (PEMP) Project: SA Water 1 Introduction This document outlines the primary environmental and heritage issues and potential impacts related to the proposed augmentation of the wastewater network at Victor Harbor. The report is broken into three key parts: Introduction - Summarises the project, construction activities and alternative options that may be been considered. Part A - documents the outcomes of the environmental and heritage assessment, including the matters considered as part of the assessment, the outcomes of any investigations or further investigation requirements. Part B - includes the Project Environment (and Heritage) Management Plan (PEMP, it identifies any regulatory approval requirements for the project (and their status where relevant) and further details environmental management measures and controls to be implemented to manage or mitigate identified impacts, particularly during construction. The Victor Harbor wastewater network upgrade (Stage 3) is being delivered via an Early Contractor Involvement (ECI) process. This assessment report is based on a high level design developed to inform pipeline alignment options. It is anticipated that further development of the project will involve additional environmental investigations and considerations. The ECI contractor should ensure that the outcomes and recommendations including mitigation measures identified and environmental controls in this report are considered during the design development for the project. Following the outcomes of the first stage of the ECI, the environment management requirements will be reviewed and updated. 1.1 Project understanding and description of works Network flow modelling has been undertaken on the Victor Harbor wastewater network to assess the current and long term flow projections against the current network capacity. The modelling indicates that parts of the network are at peak capacity and require augmentation. This project proposes a wastewater network upgrade to address current capacity issues within the wastewater network. 1.1.1 Background The Victor Harbor region has experienced strong and continuing development over a number of years. The current wastewater network is configured such that wastewater flows by gravity and pumping to the site of the old Wastewater Treatment Plant (WWTP) and then is pumped up to the new Trillity operated Victor Harbor WWTP on Greenhill Road (Refer to Figure 1). As a result of the development in the area the wastewater network is running at capacity. Modelling also shows that during peak periods the network runs over its capacity causing network surcharging and is at risk of overflows to the environment. As a result the network has been identified as needing augmentation, particularly to service new development areas. In 2006, SA Water undertook a master planning process for the Victor Harbor area to define augmentation requirements, appropriate staging of works and to develop an augmentation charge. The current project comprises Stage 3 of the identified augmentation requirements. The masterplan identified that the most cost effective solution to address the network issues was to pump the wastewater flows from the Hayborough development area (adjacent to Ocean Road) directly to the Version 0.01 dd/mm/yy Draft For Official Use Only Document ID: TBD Page 5 of 46 Uncontrolled when printed or downloaded Environment and Heritage Services – Environment and Heritage Assessment Report and Project Environmental Management Plan (PEMP) Project: SA Water new Victor Harbor WWTP with an alignment that would be able to pick up flows from some of the future development areas. This project proposes to upgrade the Victor Harbor wastewater network such that it has sufficient capacity to transfer the increasing quantity of wastewater. This increase is being generated by the growing population of Victor Harbor as well as several planned developments including a new Regional Aquatic and a Health and wellbeing Centre at the intersection of Ocean Road and Waterport Road and adjacent new housing (refer Figure 1). 1.1.2 Project Objective The objective of this project is to upgrade the wastewater network to address current network capacity issues, though the construction of a combination of new wastewater gravity mains, pump stations and rising mains that will transfer wastewater from the new Aquatic and Health Centre, due to be completed in December 2016, and surrounding development areas, to the Victor Harbor WWTP operated by Trility. 1.1.3 Proposed Scope of works The proposed project scope is to design and build a combination of new sewer gravity mains (with pipe sizes ranging between DN150 and DN200), four pump stations and rising mains (with pipe sizes ranging between DN200 and DN225) that will transfer wastewater from the new Aquatic and Health Centre and Hickenbotham Development to the new WWTP, located off Greenhills Road, for a total distance of approximately 6.2km. The scope of work also includes minor connections and decommissioning of existing wastewater pumping stations (WWPSs). 1.1.4 Alternatives considered The master plan developed in 2006 considered a range of options for augmenting the Victor Harbor wastewater system. The outcomes of this planning work identified that the most efficient cost effective solution would be to pump wastewater flows from the Hayborough development area directly to the new Victor Harbor WWTP with an alignment that is able to pick up flows from some of the new future development areas. Three pipeline alignments were considered as part of the option investigation phase for this project. The first 1.6km pipeline and the pump station adjacent to the new Aquatic and Health Centre were common for all three options. Early investigations determined that there were no other clear or feasible alignments for this section which is referred to as the “Common Pipeline Alignment”. For the remainder of the pipeline three possible alignments were investigated (Refer Figure 2). These options were been identified based on key criteria as listed below: 1. Shortest route (Option 3); 2. Route that follows road reserves as much as possible and therefore requires the least amount of new easements (Option 1); and 3. An alignment that is a compromise of the first two criteria (Option 2). This option is referred to as “developer friendly” option because the pipeline along two property boundaries, with a pump station at the lowest corner will enable developers to connect to the system by gravity. In addition a Base Case option was considered which involved not proceeding with the project at this time. This option was discounted as not proceeding with the project would prevent the connection to the Aquatic and Health Centre which effectively would prevent the opening of this centre. It was also Version 0.01 dd/mm/yy Draft For Official Use Only Document ID: TBD Page 6 of 46 Uncontrolled when printed or downloaded Environment and Heritage Services – Environment and Heritage Assessment Report and Project Environmental Management Plan (PEMP) Project: SA Water considered that not proceeding did not address the current environmental risks of overflows due to the system operating at capacity. The recommended option, Option 1, consists of laying the majority of the gravity and rising mains along road reserves as compared to the other two options (Options 2 and 3) where approximately 1.4km section will be laid in private lands resulting in large amount of easements be required, and some in previously undisturbed ground resulting highest risk of poor ground conditions/rock and greater potential to encounter Aboriginal heritage. Given these benefits, Option 1 was considered the most economic and preferred option. 1.2 Key Construction Activities Table 1 below provides a summary of typical project construction activities and potential environmental issues/impacts. It includes those activities which are likely to be undertaken as part of the works. Where an issue is identified the management / environmental controls included in Part B should be implemented.

This broad project area is characterised by a mixture of semi-rural/residential land uses located between the townships of Victor Harbor, Hindmarsh Valley, McCracken and Hayborough. The majority of the landscape within the vicinity of the proposed pipeline has been highly modified and predominantly consists of cleared paddocks interspersed with rural living dwellings. Vegetation in the project area is highly altered, with native vegetation predominantly restricted to roadsides, along watercourses and swamp/depressions and scattered paddock trees. The preferred pipeline alignment traverses a mixture of road reserve and paddocks with scattered trees. In addition, the pipeline will need to cross a gully via a pipe bridge and the Hindmarsh River via boring/directional drilling. The alignment includes land that whilst currently comprising paddocks has been identified for future development into residential allotments by Hickinbotham.

An overview of the alignment is provided in Figure 2 and 3 and summarised below: Construction of a new wastewater pumping station (WWPS) on a new site to replace the existing WWTP located at the Ocean Road / Waterport Road. The existing pump station at the intersection of Ocean Road and Waterport Road will be abandoned and the flows will be diverted to the new pump station (PS0). A new pipeline (rising main) along Waterport Road and Strawberry Hill Road which discharges to a manhole at western end of Strawberry Road. From the Strawberry Road manhole the pipeline will exit the manhole going west along Adelaide Road and gravitate along the southern boundary of Hickinbotham’s land toward the Hindmarsh River. The gravity sewer will then turn north and runs along the western boundary of the Hickenbotham land ending at a new WWPS (PS1 as per Figure 3) to be constructed at a site in the north western corner of the Hickenbotham land. The pipe will be required to cross large gully in this section, provisionally it is assumed that the gulley will be crossed using a pipe bridge.. From here, the rising main will run along Welch Road to Waggon Road. In order to cross the Hindmarsh River, the pipe will either be bored under the river or could be attached to the side of the Council Road Bridge. At the downstream of the Hindmarsh Bridge crossing, the pipe follows the road west to a point at CH3470 (see Figure 3). Downstream of CH3470,. From CH3740 the alignment option follows Armstrong Road for approximately 850m towards Day Road. It then cuts cross the corner of a paddock and joins Day Road after approximately 370m. The pipe will then follow Day Road to Greenhills Road, approximately 1,000m. It then turns west along the WWTP access road and enters the WWTP.

The assessment was undertaken on broad pipeline routes rather than on a detailed design as such the exact location of the pipeline and extent of construction impacts (i.e. limited to the road or on the road reserve) was not known at the time of the assessment. To be conservative it was assumed that the construction footprint may extend into road reserves. Native vegetation remnancy across the project area is low, with approximately 11% (4,117 ha) of the Inman Valley environmental association mapped as remnant native vegetation, of which 28% (1,150 ha) is formally conserved. As such vegetation that remains in the region is considered important of value and should be retained wherever possible. EBS identified two primary main areas along the proposed pipeline that contain stands of native vegetation as per DEWNR vegetation mapping. A Eucalyptus fasciculosa (Pink Gum) Woodland was mapped as occurring at the northern intersection of the preferred pipeline location and common alignment and a Eucalyptus camaldulensis var. camaldulensis (Red Gum) Woodland is present along the Hindmarsh River which is intersected by the Common Pipeline, south of the Victor Harbor Harness Racing Club. Refer to the full EBS report for further details. The common pipeline alignment mostly crosses cleared paddocks. It intersects Eucalyptus camaldulensis var. camaldulensis (River Red Gum) Woodland along the Hindmarsh River. There is scattered native Eucalyptus sp., native sedges and natural waterbodies along Strawberry Hill Road. EBS identified that native sedges (presumably Gahnia and Juncus sp.) are scattered on either side of Strawberry Hill Road (mostly outside the road reserve). The brackish marsh directly south of Strawberry Hill Road has been revegetated and is likely to be utilised by waterbirds. The Option 1 alignment largely follows road reserves and EBS identified that it has the potential to Version 0.01 dd/mm/yy Draft For Official Use Only Document ID: TBD Page 12 of 46 Uncontrolled when printed or downloaded Environment and Heritage Services – Environment and Heritage Assessment Report and Project Environmental Management Plan (PEMP) Project: SA Water Potential aspect/impact Tick if relevant interact existing vegetation both remmant and planted within sections. The road reserve along Days Road is lined with vegetation. The northern road reserve appears to consist of a row of planted tall, mature exotic pines trees (Pinus sp.) with an exotic grass understorey, as well as patches of mixed shrub/tree plantings (which appear to be predominantly Acacia sp. and Eucalyptus sp.). The southern road reserve appears to predominantly comprise mixed native shrub and tree plantings (assumed approximately 10 years old). There is remnant native vegetation on a sandy substrate at and approaching the intersection with Colebatch Road. Visible species are Xanthorrhoea semiplana ssp (Yacca) and Eucalyptus sp. The understorey appears to be highly degraded. Along Days Road from Colebatch Road intersection to Armstrong Road, there is remnant native vegetation scattered along both sides of the road; visible species include Eucalyptus fasciculosa (Pink Gum), Eucalyptus baxteri (Brown Stringybark) Xanthorrhoea semiplana ssp. (Yacca), Acacia longifolia ssp. sophorae (Coastal Wattle) and Leptospermum sp. (Tea-tree). Inter-mixed planted vegetation is also present. Based on nearby roadside vegetation mapping (Transport SA Roadside Survey 2005) Eucalyptus cosmophylla (Cup Gum) and a range of native understorey species could potentially be present. The road reserve on both sides of Armstrong Road (Day Road intersection to Waggon Road intersection) has previously been cut-in to construct the road and consists mostly of native tree/shrub plantings and potentially native regrowth. The road reserve along Waggon Road is lined with native Eucalyptus sp. hence the pipeline may impact on some trees in this section. Figure 6 Mapped Native Vegetation Communities in Project Area Threatened communities in project area A Protected Matters Report was generated on 7/7/2015 to identify matters of national environmental significance under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) that may occur or may have suitable habitat occurring within the project area. A buffer of 1 km around the pipeline route was applied for this search (DOE 2015). No nationally threatened ecological communities listed under the EPBC Act were identified in the EPBC Protected Matters Search as being present within the project area (DOE 2015).

In their report EBS also advise that E. fasciculosa +/- E. leucoxylon Heathy Woodland on sandy loams of flats and slopes is considered a state vulnerable ecosystem. The reserved examples are mostly small and in poor condition (DEH in progress). The E. fasciculosa woodland within the project area may be considered part of this community. Impacts to this area will need to be minimised as part of progressing the project. Gahnia filum Sedgeland in drainage lines and depressions is provisionally listed as a State threatened community (DEH in progress). EBS identified that the sedgeland along Strawberry Hill Road could be considered part of this community. However impacts to this area are not likely to be significant much of vegetation occurred outside the road reserve. Conclusion The initial vegetation assessment undertaken by EBS was a desktop assessment which involved reviewing existing spatial datasets including: vegetation cover, watercourses, DEWNR floristic mapping, biological survey sites, protected areas, DPTI roadside vegetation survey, Heritage Agreements and SEB offset areas under the Native Vegetation Act 1991. Relevant literature, aerial imagery (Google satellite and street view), and previous survey information was also reviewed by EBS. Site visits have been undertaken to review potential impacts, however no detailed ground assessments or field based survey work has been undertaken at this stage. Actual impacts to vegetation will need to be confirmed as part of further design development.

The desktop assessment did not identify any potential significant impacts to fauna though it did identify that any potential impacts to vegetation associated with the works could impact the habitat of some native species. Native vegetation has high conservation value, particularly given the low level of remnancy within the broader region. EBS identified that the habitat value for most of the pipeline alignment is low given the modified nature of the landscape. The established vegetation along Days Road and Hindmarsh River has high habitat value, particularly for birds and the Common Brush-tailed Possum. Scattered remnant paddock trees may contain hollows and also have habitat value, particularly given the low level of remnancy. The natural wetland areas along the Hindmarsh River, Strawberry Hill Road would be seasonally utilised by a range of waterbirds, including potentially threatened waterbird species. Threatened species in project area The EPBC Protected Matters Search (1 km buffer) identified six threatened birds, one threatened fish, one threatened mammal and 11 listed migratory bird species which may occur or may have habitat occurring within the project area (DOE 2015). EBS identified that some of the wetland birds species are considered as having potential to occur within the project area. The other species are considered unlikely to be present. None of the species were considered to be significantly impacted by the proposed works.

Thirteen bird species, 2 mammal species and 2 reptile species are considered as potentially present within the project area, though impacts to these species are not considered likely to be significant based on the temporary nature of the works and limited size of the construction footprint. BDBSA threatened fauna records within close proximity to the pipeline alignment are shown in the figure below. In addition to the BDBSA records, there is a record from the Atlas of Living Australia (not mapped) of the state rare Spotless Crake (Porzana tabuensis) within the marshy area along Strawberry Hill Road, on the common pipeline route (ALA 2015).

Construction works for both the pipeline and pump stations will involve excavation and associated ground disturbance. This will create a potential risk of erosion. In addition the pipeline route will need to cross a the Hindmarsh River (south of the Victor Harbor Harness Racing Club). It also intersects a large brackish marsh near the eastern end of the common pipeline route. Works in the vicinity of the river have the potential to impact water quality and release of sediment into the watercourse if not managed appropriately. Initial design work has identified that the river crossing will utilise trenchless technology which will assist with mitigating these risks. A review the WaterConnect online database indicated that groundwater depths vary from 2 m to15 m BGL along the proposed pipeline alignment. Standing groundwater has been recorded in wells at depths of approximately 2 m near Hindmarsh River and approximately 3 m near Armstrong Road Creek. Records away from the watercourses show standing water levels at depths ranging from approximately 3 m to 15 m below ground level. Groundwater levels are potentially subject to seasonal and climatic variation and perched water could also be encountered in areas of the proposed alignment. Noting these depths, particularly near the watercourses and deeper with if deeper sections of excavation are required in some sections, groundwater dewatering may be required. It is important that stormwater management be implemented during works to prevent sediment laden runoff leaving the works site and where relevant entering the River. This management should focus not only on the construction envelope but also laydown and stockpile areas. In addition, any discharges associated with commissioning of pipes must be approved via the standard SA Version 0.01 dd/mm/yy Draft For Official Use Only Document ID: TBD Page 18 of 46 Uncontrolled when printed or downloaded Environment and Heritage Services – Environment and Heritage Assessment Report and Project Environmental Management Plan (PEMP) Project: SA Water Aspects Tick where relevant Water planned discharge approvals process.

The use of plant and machinery associated with the construction works also can generate nuisance emissions if not managed appropriately. The project will involve the construction of a number of wastewater pump stations, potential odour emissions from these locations should be considered with respect to the proximity to sensitive land uses (now and associated with planned future development). Alternatives & Mitigation Measures Design phase Potential odour risks from the network / pump stations sites should be considered during design development and mitigation strategies to minimise impact on surrounding sensitive receptors incorporated where relevant. Pumping stations in particular should consider if odour control facilities are required and requirements for mitigation measures (educts (and their location), filters or dosing).

No soil testing or has been undertaken along the alignment. Given the agricultural history of the area there may be some pockets of contamination within the project alignment. It is also noted that within the Hickenbotham land in the ‘gully’ there were areas that have from the site inspection were identified as having previously been used for illegal dumping. A range of materials, drums, car parts were noted in the gully. Potential contamination and waste management in these areas will need to be considered if the works interact with the gully at this location. The Contractor should include measures in their EMP should contamination be uncovered as part of the works. No significant PASS or ASS risks identified and a review of high level geotechnical work did not indicate any soil material that would present PASS risk. However as the works will involve waterway crossing there is some potential that PASS material could be uncovered.

To minimise impacts associated with this the preferred pipeline alignment has sought to minimise requirements for easements by largely following road reserves were possible. The new pump station adjacent to the Aquatic Centre is to be located on a site identified and provided by the Aquatic Centre developers. SA Water has been negotiating with Hickenbotham to determine their preferred pipeline route and pump station location within their development area to ensure that the locations are acceptable. There will be some short terms impacts associated with construction and potential traffic delays. This will be short terms and impacts minimised though having in place traffic management where required. In addition the pipeline crossing of Adelaide Road is likely to be directional drillingto minimise impacts on road users. The overall outcomes of the project will facilitate the development and growth within the Victor Harbor township, as well as facilitate the development of the new Aquatic Centre and well being centre though the provision of critical wastewater services. As such it is considered that it will have overall benefits for the local community. Alternatives & Mitigation Measures SA Water has been negotiating with Hickenbotham and the developers of the Aquatic Centre to determine their preferred pipeline route and pump station location within their development area to ensure that the locations are acceptable. A Stakeholder Engagement plan has been developed by SA Water’s Stakeholder engagement team and this will be implemented for the project to ensure local community is aware of the project and potential impacts and mitigation measures.

The risk assessment included a desktop analysis and initial site walkover (of accessible sections). The initial analysis sought to identify areas of risk and provide initial suggested mitigation strategies associated with each option/alignment. From the outcomes of the desktop analysis of the proposed alignments, Option 1 was assessed as the lowest risk alignment of the three and on this basis would be the preferred alignment .This is largely based on the disturbance history of the surface and sub-surface. Options 2 and 3 were considered to pose a higher risk as they impact relative undisturbed surfaces and both intersect drainage lines. No previously recorded sites as per the Central Archive were identified for any of the options. The common alignment, particularly the section that runs through relatively undisturbed areas within Hickenbotham land and parallel with the Hindmarsh River was considered to present the greatest risk area. SA Water is seeking to engage with Ngarrindjeri on the project to provide a better understanding of risks and requirements associated with protection and management of Aboriginal Heritage as part of the project.

As this project is being delivered through an ECI there are a number of potential impacts that can be mitigated and should be considered during further design development. The ECI contractor should ensure that the outcomes and recommendations including mitigation measures identified in this report are adhered to and considered during the design development for the project. Key outcomes and requirements are highlighted below, further details are provided in Part A and Section 6: Flora and Fauna Design for pipeline alignments to minimise impacts to vegetation, particularly roadside vegetation and identified sensitive areas. Impacts to native vegetation will require assessment and approval in accordance with SA Water’s Native Vegetation Standard Operating Procedure. This will require further field base vegetation assessments. Pipeline alignments should avoid or minimise requiring excavations that would encroach on the tree protection zone of established trees (particularly scattered trees). An arborist assessment should be undertaken to inform requirements where works are within the vicinity of trees. Water and Water Quality Design development to consider potential requirements for dewatering during works Crossing of the Hindmarsh River to be via boring/direction drill, should this approach change potential impacts and approval requirements will need to be re assessed Air Quality Potential odour risks from the network/pump stations sites should be considered during design and mitigation requirements identified and incorporated as necessary. Noise Design for the wastewater pump stations must ensure compliance with EPA Noise Policy requirements as a minimum.

Environmental Impact Objective Performance Indicator Controls Contamination Identify potential contamination issues on site. Manage such issues to protect employees, the public and the environment. No impact to soil/groundwater associated with contaminated material. No risk to employees from encountering and managing contaminated material. Preconstruction Undertake assessment of risk of encountering contamination based on historical or surrounding land uses Construction Version 0.01 dd/mm/yy Draft For Official Use Only Page 40 of 46 Environment and Heritage Services – Environment and Heritage Assessment Report and Project Environmental Management Plan (PEMP) Project: Heritage Impact Objectives Performance indicators Controls SA Water In the case of unusual odours or visual observation being made during excavation that indicates soil/groundwater contamination work is to cease and the SA Water Environmental officer contacted. The discovery of contaminated soil and/or groundwater is to be immediately reported to the SA Water Site Representative so as the appropriate authorities can be notified. Contaminated material must be transported and disposed of in accordance with EPA requirements (licenced waste transporter and to EPA licenced facility). Waste transfer certificates retained for contaminated material and available on request. If contaminated discovered: Isolate the suspected contaminated area. o Separate any suspected soil/fill, store on impervious material (tarp/fortecon) and cover to prevent rain or wind mobilising material. Any contaminated fill requires NATA Certified Laboratory Test Results and must be disposed to an EPA licensed landfill (contact Environmental Heritage Services to arrange this) o Groundwater contamination is required by law to be reported to the EPA. o No disposal of contaminated groundwater to a stormwater or watercourse. Aboriginal Heritage Management Prevent or minimise Disturbance to cultural heritage sites Ensure all statutory requirements are complied with and controls listed below are implemented to minimise potential disturbance to unknown sites. Management of any Aboriginal discoveries in accordance with SA Waters SOP for the discovery of Aboriginal Heritage (refer Appendix A) Pre Construction For all works not limited to within building or on existing infrastructure, undertake an AAR register search to determine if known heritage sites within the works area and complete heritage risk assessment Construction SA Water’s procedure for the discovery Aboriginal Heritage must be available on site and all construction personnel inducted into this procedure. In the event of potential a potential heritage site or object being discovered during construction, works in the area must stop and the procedure for the Discovery of Aboriginal Heritage followed (refer Appendix A) Environment Impact Objective Version 0.01 dd/mm/yy Draft For Official Use Only Fire Management Ensure compliance with South Australian Country Fire Act 1989 To ensure that construction activities do not cause and emergency incident such as starting a fire.
