The Winburndale Dam Flood Security Upgrade is nearing its final stages, with 19 out of 25 pre-stressed ground anchors now installed to reinforce the dam wall. The jointly funded – $2.3 million from the New South Wales Government’s Safe and Secure Water Program and $13.75 million from Bathurst Regional Council – project is using modern engineering practices to strengthen the […]
As the need to strengthen water networks rises due to increasing urbanisation and the impact of climate change, effective pressure management is becoming indispensable. Pressure regulating valves (PRVs) can combat non-revenue water by preventing unnecessary mechanical stress and improving the longevity of networks with modern materials, a simple construction, and digital functionality. Every year, utilities worldwide lose 126 billion cubic […]
The wettest Spring on record across the Murray Darling Basin and New South Wales has brought tremendous hardship for thousands of people, and extreme vigilance by WaterNSW in safely managing the state’s inland dams.

As summer brings hot weather, Australians start cleaning out the pools, going on holiday and most importantly, preparing for bushfires, it’s vital for utilities to take the necessary precautions with bushfire season approaching for most of the country to prevent their equipment and infrastructure from accidentally causing a fire. For network operators, this means clearing vegetation near assets and equipment. […]
24 charges have been laid against United Energy for allowing trees to grow too close to powerlines in high bushfire risk areas. Contact between trees and powerlines can result in fires, electric shock and power outages, which can lead to property damage and, in serious cases, injury and death. Major electricity companies are required to keep trees and vegetation at […]
Water treatment sludge could be used to prevent 117,000km of sewer pipes in Australia from cracking in future, without any intervention by humans, helping to save $1.4 billion in annual maintenance costs.

Water utilities have advised residents to avoid sewer overflows amid the ongoing floods, while the Victorian Government commits $500,000 to assist in flood-recovery clean up efforts in its newly-announced Council Flood Support Fund. The Bureau of Meteorology […]
Proactive action has been taken at Wivenhoe Dam in anticipation of this summer’s forecast La Nina, with the dam’s temporary full supply level lowered. Queensland Premier, Annastacia Palaszczuk, announced the decision to lower the temporary full supply to 80 per cent, saying the move is to ensure the continued safety of Queenslanders and communities. “In light of forecasts from the […]
Prolonged flooding has continued in New South Wales, prompting emergency services to issue flood and evacuation orders for affected areas. New South Wales SES has released 105 Flood Warnings across the inland, western and southern parts of the state: Five emergency warnings 44 watch and act 56 advice warnings Oura Beach Camping Area and Western Pains Tourist Park have been […]
WaterNSW is closely monitoring rising storage levels at the two major supply dams for the Murrumbidgee Valley, as the Bureau of Meteorology (BoM) forecasts ongoing wet conditions. Burrinjuck Dam, on the Murrumbidgee River, was sitting at 103 per cent capacity as of 8 August 2022 up from 90.5 per cent on 2 August, having received a peak inflow of over […]
The severity of recent weather events in Australia has continued to highlight the need for climate-resilient infrastructure. Bushfires, floods, droughts and other unprecedented weather events have placed a significant strain on the Australian economy, as well as their devastating impact on both regional and metropolitan communities. Effective wastewater infrastructure designed for climate-resilience is vital to long-term sustainability. The changing climate […]
There is no such thing as a one-size-fits-all solution to the flooding crisis experienced yet again in Australia. But there is a common approach that can help mitigate risk and prepare for the future. Conversations following recent flood events have been about how stormwater infrastructure can cope with the levels of water that parts of Byron Bay, Lismore, Brisbane and […]
With El Nino and his tumultuous counterpart La Niña creating long dry summers and bushfires, followed by freak storms and flash flooding, Australians are learning to live with the disruption caused by climate change. Here, we look at how energy businesses are adapting to ensure their networks, customers and communities are more resilient to its effects.
Maintenance and repair works for the Morwell River Diversion (MRD) structure at the Yallourn mine is nearing completion, following damage caused by unprecedented flooding in 2021.
