A looming water crisis is set to grip regional Australia, and one Victorian city is already sounding the alarm! As our populations swell and the climate continues its unpredictable dance, the very water we drink is becoming a precious commodity. Imagine a future where turning on the tap for a refreshing drink might become a luxury – that's the stark reality facing many communities.
Bendigo, a vibrant regional hub in central Victoria, is staring down the barrel of a drinking water shortage in just 15 years. This isn't a distant, abstract problem; it's a concrete projection from Coliban Water, the region's dedicated water authority. Damian Wells, the Managing Director, emphasizes that constant, proactive measures are absolutely essential to safeguard Bendigo's water supply. He wisely points out, "We can't just blindly continue to rely on surface water inflows as the only solution." This highlights a critical shift in thinking – we can no longer afford to be passive about our water resources.
And here's where it gets concerning: Mr. Wells revealed that inflows into the water storages feeding Bendigo have plummeted by a staggering 53% over the last three to four decades. Think about that for a moment. Less water is arriving, while simultaneously, the demand is set to skyrocket. The City of Greater Bendigo anticipates a whopping 65% population surge by 2050, expecting to be home to 200,000 residents. This dramatic increase in people means a proportionally greater need for water.
While Bendigo currently enjoys excellent water security, Mr. Wells cautions, "But we'll have to continue to augment those sources of water, acquire water on the market, and we may also need to consider purified recycled water into the future." He further stresses the importance of foresight, stating, "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." This is the part most people miss – the need for a diverse portfolio of water solutions, not just a single, traditional approach.
In a bid to bolster supplies, the water authority is actively exploring a new groundwater source for Kyneton and Tylden, located south of Bendigo. They're currently awaiting the green light from Goulburn-Murray Water for a crucial license application.
Could permanent water restrictions become the new normal? Victoria has had permanent water-saving rules in effect since 2011, a clear indicator of ongoing water stress. These rules dictate everything from using trigger nozzles on hoses to limiting watering systems and the cleaning of hard surfaces. Just recently, Central Highlands Water escalated restrictions to stage three in several towns north of Ballarat, with groundwater levels in the Forest Hill region mirroring those experienced during the infamous millennium drought.
Professor Tony Wong from Monash University, a leading expert in Sustainable Development, echoes these concerns, noting that water security is a global challenge. "This is something that is faced by almost every nation in the world in relation to strengthening drought security," he explains. He also introduces a fascinating concept: "fit-for-purpose use of water." This means we should be using water for its intended purpose, rather than a one-size-fits-all approach. As he puts it, "that in fact water is not limiting growth, but it's the way we use it."
The future of our water might just be… recycled! Both local and state bodies are urging a move away from solely relying on rainfall, especially as the climate warms and demand escalates. Infrastructure Victoria has specifically highlighted Bendigo's potential shortfall, alongside Geelong and Melbourne, in its recommendation for the state government to pilot a facility for recycling wastewater into potable drinking water. Jonathan Spear, CEO of Infrastructure Victoria, points out the economic and environmental benefits: "Recycled water costs less than treated stormwater. It also relies less on rainfall, making it more resilient to our changing climate."
A spokesperson for the Victorian government confirmed that their water security taskforce is diligently "investigating all viable options," including those for regional communities. Significant investments are being made, such as the $25 million upgrade for the Daylesford, Hepburn, and Hepburn Springs water supply system, and the Bendigo Recycled Water Factory, aimed at boosting recycled water availability and reducing the risk of restrictions. Furthermore, $24 million in integrated water management grants have been opened to foster projects that harness the benefits of recycled water and stormwater.
However, Professor Wong offers a nuanced perspective on recycled water, suggesting that recycling all water to drinking standard might be unnecessarily expensive for regional cities and towns. He proposes a more practical approach for growing areas: installing a second tap in new homes for recycled, non-drinking water. This would allow for water-efficient uses like gardening, flushing toilets, and washing clothes, without depleting precious drinking water supplies. "That can really practically be implemented in new housing rather than relying on retrofitting a whole city," he notes.
Ultimately, Professor Wong advocates for location-specific solutions that emphasize using water multiple times, in a fit-for-purpose manner, and even connecting urban water systems with adjoining agricultural uses for greater sustainability.
