Case Study

Adelaide - Allwater

In 2011, Allwater was chosen by SA Water, owned by the Government of South Australia, to operate and maintain metropolitan Adelaide’s water, wastewater and recycled water systems for ten years. This performance-based PPP contract is an Alliance partnership that allows SA Water and Allwater to work collaboratively together in the delivery of water services to SA Water’s metropolitan customers. 

An Alliance Partnership is a form of performance-based contract where the risk and rewards are shared between the partners who work cooperatively together to achieve common goals. Features include integrated management, unanimous decision making and open book accounting. Funding is provided solely by the business owner with the non-owner partner providing the services either solely or jointly. The Adelaide contract is an outsourced alliance, whereby the majority of the workforce is provided by the non-owner partner.
