Back To ProjectsHunter Valley, NSW

Hunter Water delivers water and wastewater services, including water and wastewater treatment to over a half million residents in the lower Hunter region of NSW. The region comprises six local government areas: Newcastle, Lake Macquarie, Maitland, Cessnock, Port Stephens and Dungog; as well as a small portion of Singleton.

Hunter Water’s water and wastewater treatment works had been operated for over ten years under contract by Hunter Water’s wholly owned subsidiary, Hunter Water Australia Pty Limited.

Hunter Water chose to significantly expand on the scope of work under a new long term services contract with the intention of more clearly assigning responsibility for achieving regulatory compliance and empowering the contractor to optimise total operating performance and cost. Competitive bids were sought to identify the service provider best suited to deliver the expanded scope with award of the Treatment Operations Contract for a minimum term of eight years.

The proposed scope of the Treatment Operations Contract included:
(a) operation and maintenance of six water treatment plants;
(b) operation and maintenance of nineteen wastewater treatment works;
(c) operation and maintenance of one advanced water treatment plant
(d) supply of chemicals;
(e) optimisation of power usage;
(f) bio-solids and residuals management and disposal;
(g) delivery of minor capital works including maintenance related replacements and minor upgrades; and
(h) input to asset management strategies, maintenance planning and capital works planning
