This week’s water sector activity focused on environmental reform, infrastructure investment, affordability, water security and research, with governments, utilities and researchers progressing initiatives to strengthen resilience, support industry and improve long-term service delivery.
From the launch of Australia’s first National Environmental Protection Agency and major recycled water investment in Western Australia to emissions reduction milestones, pricing decisions and international research on freshwater recovery, the latest developments highlight the sector’s continued focus on sustainability, innovation and future planning.
National EPA begins operations
Australia’s first independent National Environmental Protection Agency officially commenced operations on 1 July, marking a major milestone in the Federal Government’s environmental law reforms.
The new regulator will oversee compliance with national environmental laws, including the Environment Protection and Biodiversity Conservation Act, while improving the consistency, transparency and integrity of environmental decision-making.
Environment and Water Minister Murray Watt said the launch represented the culmination of years of advocacy.
"The National EPA will play a critical role as the independent umpire Australia's environment needs,” he said. "It will be a strong regulator that enforces compliance with our laws, while delivering better outcomes for nature and the economy."
Goulburn-Murray Water reminds visitors to stay safe this winter
Goulburn-Murray Water is encouraging their community and visitors to take extra care around lakes, dams and reservoirs during the winter school holidays, warning that cold water presents serious safety risks.
General Manager Water Storage Services Jon McKeown said simple precautions could save lives: "Colder water increases the risk of hypothermia, and with fewer people around there's often no one nearby to help if something goes wrong."
Monash experts highlight ageing pipeline risks
Following reports of potential failures in Port Moresby's ageing water network, Monash University researchers have highlighted the importance of improving pipeline durability.
Professor Jayantha Kodikara said corrosion-resistant backfill materials developed using recycled products could help extend the life of ageing infrastructure.
"Our ongoing research is engineering corrosion-resistant backfill incorporating recycled materials, with promising early results, offering a sustainable means of extending the life of ageing networks."
New videos explain northern Victoria water management
Goulburn-Murray Water has launched a series of short videos explaining seasonal determinations, water accounting and other key allocation concepts ahead of the next irrigation season.
Northern Victoria Resource Manager Mark Bailey said the resources were designed to make complex topics easier to understand: "We want to provide individuals with an easily accessible and easy-to-understand resource that walks them through these complicated topics."
Victorian water prices approved
The Essential Services Commission has approved the maximum prices Victorian water businesses can charge customers from 1 July, with average annual bills expected to increase by around 7% in Melbourne and 5% in regional Victoria.
Commission Chair Gerard Brody reminded customers experiencing financial hardship to seek assistance from their water provider: "Victorians have rights when it comes to paying water bills. If you are struggling to pay, please contact your water business."
Research explores new approach to pollution clean-up
Flinders University researchers have identified a promising new method to improve the ability of bacteria to remove pollutants from soil and water by using naturally compatible viruses.
Lead researcher Niki Romeo said the approach could support environmental restoration, while noting further field research and regulatory assessment would be required before deployment.
"If used well, phage bioaugmentation could be used in controlled conditions to help restore polluted environments and promote microbial resilience."
Gippsland Water keeps bill increases below inflation
Gippsland Water is increasing typical customer bills by 2.8% from 1 July, marking the ninth consecutive year its increases have remained below inflation.
Managing Director Sarah Cumming said careful financial management had helped shield customers from rising costs: "We've absorbed some of the rising costs through prudent financial management, so customers aren't carrying the full impact of increased costs."
WA expands recycled water for industry
The Western Australian Government is investing $81 million to expand the Kwinana Water Reclamation Plant, increasing recycled water production by 60 per cent to support major industrial growth while reducing pressure on groundwater and drinking water supplies.
Premier Roger Cook said secure recycled water supplies would help attract future investment: "Expanding the Kwinana Water Reclamation Plant will provide industry with a greater supply of high-quality recycled water needed to help grow and diversify our economy."
SA Water appoints new operations leader
SA Water has appointed experienced UK utility executive John Penicud as General Manager of Operations and Maintenance.
Chief Executive David Ryan said Penicud's experience would strengthen operational leadership across the organisation.
"John brings deep operational experience from large and complex utility environments, along with a strong focus on safety, people and environmental outcomes."
Yarra Valley Water reaches net zero milestone
Yarra Valley Water has announced it will report net zero operational emissions for the 2025-26 financial year, achieving its target four years ahead of regulatory obligations.
Managing Director Natalie Foeng said the achievement reflected years of practical emissions reduction initiatives: "We are reporting net zero operational emissions for 2025-26, showing what's possible when you focus on real, practical action to tackle emissions."
Wastewater management reverses freshwater oxygen decline
Researchers have found that improved wastewater management has reversed declining oxygen levels across hundreds of rivers and lakes in China, despite rising water temperatures.
Published in Nature Geoscience, the study analysed 18 years of monitoring data and found dissolved oxygen concentrations increased while hypoxic events declined significantly, suggesting nutrient management can improve freshwater ecosystem health even under a warming climate.
