The looming threat of water scarcity in regional towns across Australia is becoming more pronounced, particularly in places like Bendigo, a city in central Victoria. As populations increase and climate change takes its toll, projections indicate that Bendigo could face a drinking water shortage within the next 15 years, according to the region's water authority, Coliban Water.
Damian Wells, the managing director of Coliban Water, emphasizes the need for continuous intervention to safeguard Bendigo's water supply. "We can't just blindly continue to rely on surface water inflows as the only solution," he stated candidly, highlighting a crucial point that many might overlook.
Data shows that water inflows into storage facilities upstream from Bendigo have diminished by 53 percent over the past three to four decades. This decline poses a significant challenge, especially as demand for water is expected to soar due to population growth in regional areas. The City of Greater Bendigo anticipates that by 2050, its population will swell to around 200,000—a staggering increase of 65 percent compared to the figures recorded in the 2021 census.
Currently, Bendigo enjoys a relatively secure water supply, according to Mr. Wells. However, he warns that it is imperative to enhance these sources through various means, such as acquiring water from the market and potentially incorporating purified recycled water in the future. "Under climate change projections, we would be viewed as amateurs if we're not thinking about having a whole range of options up our sleeve," he explained, urging proactive measures.
The water authority is actively exploring new groundwater supplies for nearby towns Kyneton and Tylden, situated south of Bendigo, and is awaiting the results of a recent licensing application submitted to Goulburn-Murray Water.
Since 2011, permanent water-saving regulations have been enforced across Victoria. These rules mandate measures such as using trigger nozzles on hoses, imposing limits on watering systems, and restricting the use of water for cleaning hard surfaces like driveways.
Recently, Central Highlands Water escalated water restrictions from stage one to stage three in towns located north of Ballarat, including Smeaton and Newlyn. The authority noted that groundwater levels in the Forest Hill area are reminiscent of conditions experienced during the millennium drought, raising serious concerns about future water availability.
Professor Tony Wong, a Monash University expert in Sustainable Development, points out that water security challenges are not unique to Bendigo; they are global issues faced by many cities and countries. "This is something that is faced by almost every nation in the world in relation to strengthening drought security," he remarked.
Many urban areas are now considering innovative approaches to water usage, emphasizing that how we utilize water can significantly impact growth rather than the mere availability of it.
In light of the warming climate and increasing demand, local and state officials are cautioning against an over-reliance on rainfall. Infrastructure Victoria highlighted the impending shortfall in Bendigo, alongside Geelong and Melbourne, suggesting that the state government should consider piloting a facility designed to recycle wastewater for drinking purposes. "Recycled water costs less than treated stormwater," explained Jonathan Spear, CEO of Infrastructure Victoria. "It also relies less on rainfall, making it more resilient to our changing climate."
A representative from the Victorian government stated that its water security taskforce is currently exploring all viable options for regional communities. They announced a $25 million investment aimed at upgrading the water supply system for Daylesford, Hepburn, and Hepburn Springs, as well as enhancing the Bendigo Recycled Water Factory to promote recycled water use across central Victoria and reduce the likelihood of water restrictions.
Furthermore, the government has allocated $24 million in grants for integrated water management projects aimed at maximizing the benefits of recycled water and stormwater for both communities and the environment, thereby alleviating pressure on drinking water supplies.
Professor Wong cautioned that recycling all water to meet drinking standards may be unnecessarily costly for smaller regional towns. He suggested that in expanding areas where new suburbs are being developed, homes could be equipped with a second tap for non-drinking recycled water. This simple adjustment would conserve drinking water for essential uses like gardening, toilet flushing, and laundry. "That can really practically be implemented in new housing rather than relying on retrofitting a whole city," he noted.
He further stressed that solutions should be tailored to specific locations. By utilizing water multiple times in a manner suited for its purpose and establishing connections between cities, towns, and adjacent agricultural areas, greater sustainability can be achieved.
As we reflect on this pressing issue, what do you think? Should regions like Bendigo invest in recycling technologies, or are there alternative solutions that deserve consideration? Let's discuss!
