Australia’s New South Wales government has granted approval for Hunter Water to proceed with the construction of a seawater desalination plant in Belmont, with building expected to commence by late 2024, reports Utility Magazine.
The $530 million project represents a critical investment in the region’s water security, ensuring the Lower Hunter is better equipped to face future droughts. As the largest regional economy in New South Wales, the area is highly susceptible to dry periods, and this plant is seen as a vital safeguard for the region’s long-term prosperity.
Part of the Lower Hunter Water Security Plan—a comprehensive strategy designed to bolster the region's water resilience—the desalination plant will serve as a key element in securing a sustainable future for the community. According to the government, the plan enjoys widespread community support, thanks to its potential to improve both regional health and economic growth.
Once operational, the desalination plant will produce up to 30 million litres of drinking water per day, independent of rainfall, which will account for around 15% of the Lower Hunter’s average daily water consumption.
Earlier this year, Hunter Water lodged a Modification Report with the NSW Department of Planning, Housing, and Infrastructure, requesting to shift from a temporary drought response facility to a permanent desalination plant. The modification was approved by the government, which praised the proactive approach to securing the region’s water supply.
In line with the state's commitment to achieving net-zero emissions, the new plant will be powered by renewable energy
In line with the state's commitment to achieving net-zero emissions, the new plant will be powered by renewable energy. Funding for the project will be drawn from Hunter Water customer bills, with the updated pricing structure taking effect from July 2025.
NSW Minister for Planning and Public Spaces, Paul Scully, highlighted the importance of water security for the region’s future: "Locking in a drinking water supply that will support the future of the Lower Hunter for years to come is a win for the community and will support a thriving community."
Yasmin Catley, Minister for the Hunter, added: “This is a great step towards securing a reliable, sustainable water source for the Lower Hunter.
Minister for Water, Rose Jackson, noted: “One of the key advantages of desalination is that it’s a rainfall-independent source of water, which is safe and reliable regardless of changes in weather or climate. With planning approval modification finalised to facilitate the revised design and operational proposal, Hunter Water can commence the construction phase, and take another step towards meeting the evolving needs of the region in a changing climate.”
The project has garnered strong community backing, with the plant expected to alleviate pressure on the region’s dams by diversifying its water sources. Darren Cleary, Managing Director of Hunter Water, underscored the urgency of the plant, noting that water levels in the area can drop dramatically within a few years of drought.
“The Belmont Desalination Plant is an integral part of the Lower Hunter’s water system, and it will help us manage water security while addressing dam safety issues at Grahamstown Dam,” Cleary said. He acknowledged the cost implications for customers but emphasized that support programs would be available to help ease the financial burden.
