ADELAIDE DESALINATION PROJECT 1. Brief project overview  The Adelaide Desalination Project (ADP) is the largest water infrastructure project ever completed in South Australia. This exceptional facility can produce 100 billion litres of desalinated drinking water per year; 50% of Adelaide’s current drinking water needs. Delivery of this complex piece of infrastructure has been a massive undertaking.  The megaproject was initiated at a time when there was increasing uncertainty on the availability of a secure, long term, water supply and South Australia was under severe water restrictions. The South Australian Government set‐up the Desalination Working Group with an independent Chair. This group considered all possible options for the State’s water security and recommended a desalination plant.  The vision for the project was to build a long term, sustainable and cost‐effective infrastructure to secure South Australia’s water supply now and into the future.  To mitigate the significant risk of the State running out of water, local and national resources were harnessed through a rapid response process.  In February 2008, SA Water was appointed the lead agency responsible for the project and the Government supplemented this with a whole‐of‐government approach to secure the Major Development approval. As part of this approach, a senior Steering Committee, comprising Chief Executives of the key government agencies, was appointed by the Government to provide strategic guidance to the project team and ensure ‘single window’ process for stakeholder engagement.  An early contractor involvement process was used by SA Water to initiate critical works by the successful tenderers before contract award. This included early commitment of long‐lead items and separate procurement of the power and transfer pipeline infrastructure.  A key component of the successful delivery of the project included learnings that were brought from other Desalination Plants and incorporated into the project’s durability plans, manufacturing inspections and environmental outcomes.  The main works package was implemented under a “DBOM” (design, build, operate, maintain) structure, with the winning consortium providing a “whole of life” service from project inception, including a 20‐year O&M term. The contractual arrangements also enabled SA Water to exercise an option to double the capacity of the desalination plant at any time (which SA Water did, within 6 months of contract award).  The project successfully overcame numerous challenges associated with geotechnical conditions and weather through a highly effective governance structure and issue resolution process. The focus of the model was accountability, transparency, collaboration and resolution. The structure utilised a Project Control Group with agreed rules of engagement which empowered this group to test, challenge and resolve issues progressively.  This project has set a new standard for desalination plants around the world in project planning and development, market engagement and project procurement, environmental performance, durability, energy efficiency. It provides an insurance policy against future droughts for the people of South Australia.  Through full engagement of the parties, the project was delivered 19 days ahead of the original approved timeline of end December 2012. This included a full and final resolution of all issues between parties prior to project handover within the original approved budget of $1.824 billion. 2.

Zero lost time due to industrial relations is a benchmark for any large construction project in the world!  A contracting approach and governance structure supported collaboration, best for project outcomes and issue resolution, within a hard money risk allocation and contract. Full and final resolution of claims and issues between the parties achieved prior to project handover.  Project completed within budget and ahead of the original approved timeline. 4. Benefits to the community 
The project contributed to growth of professional delivery capability with 600+ businesses, global contractors and project partners working together to deliver a large asset, contributing to water sector development with: 10,000+ personnel inducted and trained at the site, and 200+ specialised welders trained at dedicated local facility. 
The project involved community and stakeholders with 15,000 visitors to the site and over 200 community presentations. 
The plant’s building design, the site‐wide landscaping with indigenous plants and the rehabilitation of the degraded creek has improved the overall visual amenity of the area. 
By recognising the cultural significance of the area an architecturally designed Kauwi Interpretive Centre and Interpretive Trail has been built and provides a public gateway to the plant. The Interpretive Centre is an interactive learning space to inform and engage the community on desalination, sustainability, cultural heritage and water resource management. It features interpretive displays about local Aboriginal Kaurna culture and also provides educational opportunities to school children which are linked to the Australian education curriculum. 

This critical infrastructure underpins future economic and business growth and provides a community amenity for South Australia. The ADP provides water for good, for economic growth and prosperity for Australia. 5. ADP ‐ Short Summary 
The ADP is the largest water infrastructure project ever completed in South Australia, delivering 50% of Adelaide’s drinking water from a climate‐independent source. 
The Adelaide Desalination Plant embraces key challenges of our generation and delivers one of the lowest carbon foot‐prints of any desalination plant in the world; its construction showcases innovation, technology, collaboration, superb environmental features and build quality. 
The project actively sought and delivered genuine collaborative outcomes with industry and Governments and set new standards for best practice in planning and development, market engagement, durability and plant performance. 
The significant risk of the State running out of water has been translated into a vision for the future that will provide infrastructure for growth and economic development. 
This world class project was delivered 19 days ahead of the original approved timeline of end December 2012 and within the original approved budget of $1.824 billion. 6. Partnership between the private and public sector 
The South Australian Government appointed a Steering Committee comprising Chief Executives of all key government agencies. This was a highly successful initiative in driving efficient and effective collaboration throughout the State Government, most particularly with the Major Development approval and Procurement phase of the project. 
Building close working relationships between the multiple stakeholders was recognised as essential for the safe delivery of this complex and large infrastructure project. The strong collaborative nature of the relationships between SA Water, the project partners and their subcontractors was fostered by having multidisciplinary teams fully engaged from the outset. O&M Operator being part of the project team from inception brought operability, operational performance and durability perspectives early in the design & build process. 
Co‐location and on‐site presence of teams brought early and valuable input into key decisions and expertise to the review processes. The party best able to manage key risks did so ‐ this included SA Water 
All construction projects present challenges with unanticipated events. It is not unusual for projects, let alone mega projects, to become bogged down in commercial issues which can become a distraction from the main objective of delivering project outcomes. This risk was recognised early by the project participants in the establishment of a robust governance process which utilised features of ‘alliance contracting’ and resulted in the project being completed within the original approved timeline, within budget, and with a documented full and final resolution of all claims and issues between the parties. 7.
