LGA Local Government Association of South Australia LGFA Local Government Finance Authority NWC National Water Commission WSA Water Smart Australia Formerly known in SA as Septic Tank Disposal Schemes (STEDS) STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia EXECUTIVE SUMMARY The Australian Government’s Watersmart Australia program was announced in 2006 and the LGA worked closely with Councils and the SA State Government to assemble a ‘Statewide’ submission proposing the upgrading of many small CWMS to achieve water recycling standards. The LGA submitted that aggregating a large number of small regional projects through one contract brokered by the LGA met the innovation criteria of the NWC project because no such large scale project had been attempted previously. Moreover, in the absence of the aggregated project model, small regional communities would not have been able to access Australian Government funding, thereby losing the opportunity to benefit from wastewater recycling and reducing their demands on existing water sources. Following agreement with the NWC, the LGA developed and lodged the submission, which included 35 Councils2 nominating 63 projects with a total estimated capital cost of approximately $90 million. In June 2007, the Australian Government announced a grant of $20 million for the project and a Deed of Agreement between the LGA and the NWC was signed on 1 November 2007. In the period between July 2007 and June 2011, the LGA worked with Participating Councils to ensure the delivery of the project. The task of coordinating a project with a capital value of $90 million involving 63 individual projects working with 35 separate Councils was indeed challenging for the LGA. However, as recorded in this final report, the LGA believes that the agreed objectives for the Statewide Wastewater Recycling Project, including the demonstration of an innovative project management approach to deal with multiple small but important projects in regional towns, have been achieved. As at 31 May 2011, the Statewide Wastewater Recycling project has achieved the following ‘headline’ results: 28 councils completed and delivered 56 CWMS wastewater recycling projects; $75 million capital expenditure on essential infrastructure in regional SA; $16.94 million Australian Government grant funds allocated to councils; 7,534 ML per annum estimated volume of treated wastewater recycled with an equivalent reduction in the demand on the River Murray and other water resources. This report includes all but one of the projects completed by participating Councils. A further project (District Council of Robe) was granted a special approval to complete its project by 30 June 2012. This project was delayed by unforseen planning issues outside of the Council’s control. There have also been associated benefits for regional communities through the upgraded CWMS being engineered to modern standards, increasing environmental and operational performance and enhanced amenity through irrigation of public spaces and recreation areas. When considered together with the ongoing grant program from the State Government for the construction of new CWMS there has been a massive investment in regional wastewater infrastructure over the past four years in an outstanding partnership between the Commonwealth, State and Local Governments. The LGA, participating Councils and their communities congratulate the Australian Government for its significant contribution to this achievement including the successful demonstration of an innovative project management, which has delivered many small projects through a single contract management arrangement. 2 referred to in this report as ‘Participating Councils’ DME 68854 STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia 1 INTRODUCTION The decade from 2000 was one of severe drought throughout most of Australia, particularly in those regions reliant on water supplied from the River Murray. In a plan to preserve water for critical human needs the State Government imposed progressively more severe water restrictions on the use of water for commercial, agricultural and recreational irrigation purposes. Many regional Councils were forced to restrict the use of potable water supplies used to irrigate community open spaces and recreation areas. The LGA, in consultation with its member Councils identified that an opportunity existed to utilise ‘fit for purpose’ treated wastewater from existing CWMS for irrigation purposes which were being lost to the environment through evaporation, leakage or overflow. However, systems would need upgrading to improve the quality of the available wastewater. Irrigation distribution systems would also need to be installed. Pursuing this objective would provide a ‘new’ source of water treated to a standard fit for irrigation purposes as an alternative to using potable water, thereby reducing the demand for water from the River Murray or groundwater resources. When the Australian Government, through the NWC, established the ‘Water Smart Australia Program’ the LGA held discussions with the NWC regarding the possibility of the LGA seeking to aggregate a large number of small projects in individual Councils into a single funding application be considered by the NWC as a single project for funding purposes. All Councils with CWMS were invited to participate in the funding application. 39 Councils representing 69 individual CWMS, registered an interest, provided preliminary project proposals and cost estimates. The LGA’s governing body, the LGA State Executive Committee, endorsed the lodgement of the final version of the Statewide Wastewater Recycling Project in mid 2007. On 27 June 2007, the Hon Malcolm Turnbull MP, the then Minister for the Environment and Water Resources, announced a $20 million funding grant from the Water Smart Australia program for the project. Representatives of both parties signed the funding deed for this project on 1 November 2007. The LGA State Executive Committee delegated the CWMS Management Committee to manage the implementation of the project. The Management Committee played a vital role in the governance of the project, especially maintaining the partnership approach between the Australian Government, State Government agencies, the LGA and Participating Councils. Representatives of DEWHA and DSEWPaC were ex officio members of the committee throughout the life of the project. 2 THE PROJECT DEVELOPMENT PROCESS As stated above, after the announcement of the Water Smart Australia Program, the LGA invited all member Councils that operate CWMS schemes to register an interest to be a part of an LGA administered aggregated project application. Councils were advised that nominated projects must include water conservation components that would directly reduce the drain on the River Murray or other potable water resources. 39 Councils submitted registrations of interest for 69 individual CWMS projects with a total preliminary cost estimate of approximately $90 million. After the announcement of the $20 million grant in June 2007, there was significant further consultation between the NWC and LGA officers to settle the final details of a Deed of Agreement between the Commonwealth of Australia and the LGA for the operation and management of the project. The Deed of Agreement was signed in November 2007. During the period of negotiation and prior to signing of the Deed of Agreement, the LGA took the following steps: confirmed the role and responsibilities of the CWMS Management Committee as provided for in the Deed of Agreement; invited a nominee of the NWC to serve on the CWMS Management Committee for the duration of the project; DME 68854 1 STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia 3 changed the meeting schedule of the Committee from Quarterly to bi-monthly to take into account the added workload and reporting regime; appointed the CWMS Program Manager as the Statewide Wastewater Recycling Scheme Program Manager; called and assessed tenders from qualified Engineering Consulting companies for inclusion on an LGA CWMS Panel of Preferred Consultants, to streamline planning, design and approval processes and to minimise design and consulting costs; recommended Consultants from the panel to Participating Councils based on prior relationships and regional considerations; and determined, as a result of the $20 million available, that subsidy would be distributed between all eligible projects on an equitable basis. Projects would receive 24.9% of capital cost with the maximum grant allocation capped at $1 million dollars for any single project, subject to special circumstances and/or innovation. CONDUCT OF THE PROJECT After the Deed of Agreement was signed, the following actions were taken: a Copy of the Deed of Agreement was sent to every Council that had indicated its willingness to participate; a letter, highlighting Council responsibilities and procedures, was sent to every Council accompanied by a standard Participating Council form requiring each Council to formalise its commitment to the project by signing and returning the form now that final grant allocations were confirmed; and the creation of a Statewide Wastewater Recycling fund with the Local Government Finance Authority (LGFA) in accordance with the requirements of section 6.5 of the Deed. The CWMS Program Manager was given the responsibility of managing the operational aspects of the project by working with Councils to ensure that the approved projects were completed in accordance with statutory obligations, where applicable. The CWMS team met with Council officers and/or Council consultants during site visits on numerous occasions during the project design and construction phases depending on the scope and complexity of the project. As a result of relationships created by State Government agency representation on the CWMS Management Committee, the CWMS team was often able to facilitate meetings between Councils, consultants and the State agencies, which assisted in streamlining the required approval processes. The CWMS team was also responsible for collecting milestone reporting data for the LGA and the CWMS Management Committee for transmission to the Department for approval including the identification of any significant issues or barriers to meeting the milestone objectives. A project progress report was submitted to each meeting of the CWMS Management Committee for the life of project. Exception and variation reports were also submitted to the Committee to consider individual Council issues, proposals for funding reallocations or reports where project progress was a concern. The CWMS Management Committee was required under the terms of the Deed of Agreement to submit Milestone reports to the Department for each 6 monthly stage of the project, reporting on achievements the targets included in the Deed of Agreement. Release of the funding allocation for each Milestone was dependant on agreed Milestones being met, or the Department being satisfied that any explanation for not attaining a particular Milestone was satisfactory. The Deed of Agreement also required that by September of each financial year of the project and within 60 working days of conclusion of the project that a financial audit of the project is carried out by an independent auditor. A copy of the project finalisation audit statement is provided (Appendix 1). DME 68854 2 STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia 4 PROJECT VARIATIONS The Deed of Agreement between the LGA and the Australian Government represented by the NWC was signed on 1 November 2007 and provided for: 35 Councils, representing 63 projects; project completion date of 30 June 2010; total estimated project capital cost of $89,727,000; Water Smart Australia grant $20 million; Councils capital contribution $69,727,000; and estimated recycled water to be saved 8,243 ML per annum. In the months after the Deed was signed, Councils carried out more detailed project investigation and designs and updated cost estimates for their nominated projects. In some instances, meetings were held with the various statutory bodies to resolve potential conflict or difficulties regarding the granting of project approvals. In some instances, Councils assessed the design on a cost/benefit ratio to determine if the actual volumes of recoverable wastewater would be worth the high capital cost of implementation and ongoing operation. As a result of the more detailed work including discussion and negotiation with members of the LGA project management team, a number of Councils decided not to proceed with this project and advised the CWMS Management Committee accordingly. A report was submitted to the CWMS Management Committee at the February 2009 meeting outlining the various project variations including: projects withdrawn by Councils; projects where the cost estimate was reduced and the grant allocation was reduced accordingly; previously considered and approved additional replacement projects; previously approved expanded projects; project submissions received seeking additional grant funding; and ‘at risk’ projects.

In addition, a project variation by the City of Port Augusta resulted in a total project cost reduction from $2,265,000 to $1,492,000 that resulted in a reduction in the grant allocated from $564,000 to $371,500. There was no change to estimated recoverable wastewater.

There were also a number of problematic projects previously reported to the CWMS Management Committee and DEWHA that resulted in construction of projects not being commenced. The decision not to proceed with these projects by the Councils was not made in sufficient time to enable the CWMS Management Committee or DSEWPaC to consider re-allocation of the grant funds to other projects. These projects were: Port Pirie Regional Council: Napperby, Pt Pirie and Crystal Brook Northern Areas Council: Gladstone Copper Coast Council: Kadina, Wallaroo A consolidated list of project variations is included as Appendix 3. 6 PROJECT COMPLETION Individual projects were completed throughout the duration of the project. Some less complex projects were completed early in 2008 with the balance being completed progressively through to March 2011. As outlined earlier in this report, one project (Robe) was granted a special approval to be completed by 30 June 2012 and is therefore not included in this report. DME 68854 5 STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia The regular report to the CWMS Management Committee and the 6 monthly Milestone reports to DEWHA reported individual project progress, during the reporting period estimated project completion dates and flagged problematic projects were indicated. Re-allocation of project funding as a result of the withdrawal of projects leading to the addition and or expansion of projects also coincided with a record wet winter in 2009-10. There was also significant concern about the potential future of a number of problematic projects, particularly the 3 Port Pirie projects and the Robe project. As a result, an application was submitted DEWHA in April 2010 seeking to extend the project deadline beyond June 2010. This request was approved on 2 June 2010 approving an extended project deadline up to 31 March 2011. All project sites were visited by a CWMS project team member on a number of occasions to meet with the responsible Council Officer and/or the consultant, particularly on the receipt of advice of project practical completion. Certificates of Practical completion have been issued for all of the 56 projects completed. 7 PROJECT EVALUATION From almost every perspective, this project has been very successful. The project has resulted in the upgrading of 56 CWMS schemes to a standard that has enabled the reuse of treated wastewater that is fit for purpose for the irrigation of a range of purposes, for example: Council reserve areas; Council sporting facilities; Council landscaped areas; golf courses; a race course; broad acre cropping grasses; grape vines; and a commercial turf farm. This resulted in a significant reduction in the use of potable water sourced from the River Murray, underground bores or other water catchments. Restrictions on the use of these water sources created significant problems during the drought. Production of ‘fit for purpose’ recycled wastewater from CWMS has enabled Councils to maintain or increase their water regime on ovals and sporting grounds, activities on these areas are safer as a result of softer playing surfaces. Improvement to CWMS schemes by upgrading and lining treatment and storage lagoons and by constructing mechanical Wastewater Treatment Plants to replace leaking facultative lagoons has resulted in a reduction in wastewater overflow or seepage into nearby groundwater, reducing the risk to public health. 27 Mechanical Wastewater Treatment plants were constructed during this project and two plants were upgraded. The quality of the treated wastewater for recycling is significantly improved and the water can be used direct from the plant losses through evaporation of stored water is reduced. The cost of this remediation work and wastewater recycling effort has been a significant investment by regional Councils (with the assistance of the NWC funding) and the rural communities of South Australia will be the long term beneficiaries of this project, including during periods of prolonged drought.

In the absence of metering, volumetric calculation for CWMS systems is based on the number of user properties (both residential and non residential), the number of persons, the estimated evaporation rate for the region, the estimated amount of stormwater infiltration and other local factors. The consulting industry uses these estimates, plus the estimated potential growth in the locality over a five or ten year horizon (depending on anticipated high or low growth estimates) to determine the design parameters to be used in designing the capacity of a CWMS. During periods of drought, the estimated volumes available for recycling can be significantly affected when the community becomes much more careful about the use of water. During the drought period, the volume of wastewater being received and treated by SA Water at the major metropolitan sewerage treatment plants was reduced by as much as 30% below usual volumes. Estimates are more difficult to calculate if harvesting and reuse of stormwater is included, particularly where water retention/detention storage areas are limited. In the initial submission by the LGA to the NWC, the estimated volume of treated wastewater likely to be available was based on preliminary designs and desktop calculations. Following project approval, the signed Deed of Agreement provided for 35 Councils representing 63 projects to produce an estimated volume of 8,243ML of treated wastewater for recycling. At the conclusion of the project, taking into account all of the various projects that were either withdrawn, added, expanded or did not proceed, using the standard calculation methodology produced the following revised estimates. 56 completed projects will produce an estimated volume of treated recycled wastewater of 7,534ML (Appendix 4). It should be noted that if the estimated wastewater volumes from the 7 projects that were withdrawn were added (866 ML), the total estimated volume would have been 8,400 ML, which would have exceeded the estimated volume originally provided in the Deed of Agreement. It will be at least two years following the completion of each project before an accurate assessment can be made of the actual volumes of treated wastewater being recycled. Collation of this information for many of the systems will be made easier in the future by inclusion of flow meters in the construction design for CWMS. Furthermore, many Councils will experience significant development over the current planning horizon of 5 to 10 years resulting in a significant growth in the recycled wastewater volumes. Areas of known significant population growth include: Alexandrina (Goolwa and Strathalbyn) Barossa (Nuriootpa) Clare & Gilbert Valley (Clare) Coorong (Meningie) Light (Kapunda, Freeling) Loxton/Waikerie (Loxton) Mt Barker (Mt Barker) Renmark Paringa (Renmark) DME 68854 7 STATEWIDE WASTEWATER RECYCLING PROJECT FINAL REPORT Local Government Association of South Australia Councils involved in this project are now much more aware of the potential for wastewater recycling and some Councils are also investigating or implementing stormwater harvesting projects to complement the water recycling work done to date. Therefore, over time, it is expected that the recycled water targets in the original deed will be exceeded. 9 FINANCIAL OUTCOME The Deed of Agreement between the LGA and the NWC made financial provision for aggregation of 63 projects nominated by 35 Councils with the estimated total capital cost of the project being $89,727,000 (GST exclusive). The grant allocated from the Watersmart Australia Project to subsidise the expenditure was $20,000,000 (GST exclusive). The Deed of Agreement required the NWC to be provided with an audited statement of income and expenditure for the period of each financial year of the project and within 60 working days of the completion of the project. The audited financial statement representing part of this project completion report 2011 is also provided (Appendix 1). Income from agreed Milestone payments received in advance from DSEWPaC was invested with the Local Government Finance Authority at commercial rates in accordance with the provisions of the Deed of Agreement. Income from the investment of the advance milestone payments were used to fund the cost of management and administration of the program by the LGA. DME 68854 8
