This week’s water sector activity focused on climate action, infrastructure resilience, wastewater innovation and long-term water security, with governments, utilities and researchers advancing initiatives to strengthen essential services and prepare communities for future challenges.
From new opportunities to contribute to Australia's COP31 leadership and innovative approaches to removing microplastics from wastewater, to infrastructure renewals, climate adaptation research and water conservation initiatives, the latest developments highlight the sector's continued focus on sustainability, resilience and practical innovation.
Applications open to support Australia's COP31 role
The Department of Climate Change, Energy, the Environment and Water has opened applications for organisations and individuals to contribute to Australia's participation in COP31, including proposals for the Australian Pavilion program and the Climate Conference Travel Support Program.
Australia will serve as President of Negotiations when COP31 is held in Antalya, Türkiye, from 9 to 20 November.
The department said the summit presents "a significant opportunity for Australia as we partner with Türkiye and the Pacific to deliver this event" and showcase Australia's leadership, innovation and clean energy progress.
Morwell plant upgrade improves wastewater performance
Gippsland Water has upgraded an aerator at its Morwell wastewater treatment plant to improve treatment efficiency, strengthen operational flexibility and reduce operating costs.
Managing Director Sarah Cumming said the investment would improve performance during periods of higher inflow.
"The new high-speed aerator will improve efficiency by delivering oxygen into the treatment process, helping maintain the conditions for micro-organisms that help treat the wastewater," she said.
New method removes more than 90% of microplastics
RMIT University researchers have demonstrated a new wastewater treatment approach that combines microbubbles and nanobubbles to remove more than 90% of microplastics without major infrastructure changes.
Associate Professor Biplob Pramanik said the findings offer a practical solution to a growing environmental challenge.
"Our approach is simple to implement and significantly increases the removal of microplastics during the primary stage of treatment," he said.
Maroochydore renewal strengthens future services
Unitywater is progressing a major renewal of the Maroochydore Wastewater Treatment Plant as part of its $500 million replacements and renewals program to support reliable services for a growing population.
Executive Manager Sustainable Infrastructure Solutions Mike Basterfield said the project had delivered significant savings while maintaining operations.: "Through strong collaboration, our planning, operations and capital delivery teams have identified and implemented innovative solutions to optimise the plant's performance for future demand and requirements."
Hunter Water urges continued water saving
Hunter Water is encouraging customers to continue making Smart Water Choices despite recent rainfall lifting Lower Hunter storage levels above 70%.
Acting Executive Manager Strategy and Engagement David Derkenne said recent inflows were welcome but long-term conservation remained essential.
"Saving water isn't just something we do during drought. It's something we can all practise every day, in any weather," he said.
SA Water unveils new public artwork
SA Water has unveiled a large-scale mural at its Lobethal pump station as part of its Art on Infrastructure program, celebrating the connections between water, people and the environment.
Manager of Brand and Community Connection Kellie McDonald said the artwork transforms essential infrastructure into a community asset.: "Water is one of nature's great connectors, linking communities, landscapes and ecosystems, and Lucinda has captured that beautifully in Force of Nature."
