Over the last twelve months, I’ve attended eight major water industry events in Mexico City, Shanghai, Valencia, Amsterdam, Oklahoma City, New Orleans, and more. No matter where I went, the pattern was the same: almost every presentation kicked off with warnings about water scarcity. The threat is real, and the numbers are sobering: by 2025, 1.8 billion people are expected to live in regions facing “absolute” water scarcity, and two-thirds of the world’s population could be under stress. But after hearing this message on repeat, I believe it’s time for us as an industry to break out of this loop. We need to change the conversation.
For years, our sector has sounded the alarm about scarcity, drought, and crisis. These warnings have raised awareness, but they’ve also become a convenient excuse for political inaction. As technology providers, innovators, and utilities, we have the power—and the responsibility—to shift the narrative. It’s time to focus on what’s possible, not just what’s missing.
Too often, politicians and officials fall back on water scarcity as a reason for delay or half-hearted measures. “There’s only so much we can do; water is running out”, they say. But scarcity isn’t always about a lack of water. More often, it’s about a lack of action, investment, and ownership. Global water use is rising at more than twice the rate of population growth, but we have far more tools at our disposal than we did even a decade ago.
Let’s start with the good news: we’re not short on solutions. Desalination is now cheaper and greener, thanks to advances in materials and renewable energy. Decentralised water systems, once dismissed as too expensive or unreliable, have become cost-competitive and robust, thanks to modern treatment tech, real-time monitoring, and modular design. Nanotechnology and biotechnology are letting us filter and purify water at the molecular level, opening new doors for safe reuse. Utilities are using smart sensors and analytics to find and fix leaks before they become disasters, and wastewater recycling is becoming mainstream. These aren’t just theoretical fixes; they’re working right now.
It’s about resilience, energy savings, and building a future that works for everyone, even as populations grow and the climate changes
In Singapore, water security relies on relentless innovation and integrated planning. The “Four National Taps” strategy—local catchments, imported water, NEWater (recycled), and desalination—ensures a resilient, diversified supply. NEWater already meets 40% of demand, with a goal of 55% by 2060. The Keppel Marina East Desalination Plant treats both seawater and reservoir water, optimising energy use. Importantly, Singapore has transformed public perception, making recycled water a source of national pride.
Hong Kong also excels in water management. Its Total Water Management Strategy, updated in 2019, focuses on managing demand and diversifying supply. Public education, mandatory water-saving devices, and aggressive leakage control help contain demand, while seawater flushing (used by 80% of residents) reduces freshwater use by up to 20%.
Namibia, the driest country in southern Africa, is a model of resilience. Windhoek has pioneered potable water reuse since 1968. Today, the New Goreangab Water Reclamation Plant supplies about a quarter of the city’s needs by blending treated wastewater with dam water. Namibia’s Managed Aquifer Recharge program stores surplus water underground for droughts. In rural areas, community management empowers locals to operate water points, boosting efficiency and ownership. Rural access to potable water now exceeds 92%.
Orange County, California, sets another benchmark. Its Groundwater Replenishment System (GWRS) is the world’s largest advanced water purification project for indirect potable reuse, producing up to 130 million gallons daily, enough for a million residents. The GWRS purifies treated wastewater and recharges it into the local groundwater basin, supplying up to a third of the county’s water with less energy than importing or desalination.
Dubai and the UAE are also leading in water recycling. Dubai now reuses 90% of its wastewater, aiming for 100% by 2030. The city delivers around 700,000 cubic metres of treated water daily for irrigation, cooling, and firefighting. The Jebel Ali plant processes 675,000 cubic metres a day, and new initiatives are recharging groundwater with recycled water. By 2030, Dubai expects to double recycled water output and save over half a billion dollars a year.
Now, we can also leverage industry as a powerful part of our arsenal. Industries are increasingly stepping up as essential partners in water solutions, driven by the water-positive concept. This means companies commit to returning more water to the environment than they consume, through efficiency, and by actively replenishing local sources and improving water quality. When industry draws less from aquifers, maximises reuse, and discharges cleaner water, it competes less with local communities and reduces pollution, making water more available for everyone.
Water abundance isn’t a fantasy; it’s a choice. The more we talk about what’s working, the harder it becomes for officials to use old excuses
At Desalytics, we’ve made it a strategic priority to focus on industrial clients because we see their pivotal role in water sustainability. Globally, more companies are embracing water positivity. Microsoft is running over 90 water replenishment and access projects in 25 locations, including stormwater capture in Madrid (up to 200 million litres annually), AI-driven leak detection in London and Phoenix, and major restoration efforts in Mexico. Coca-Cola has improved water efficiency by 20% over 2004 levels, saving about 50 billion litres of freshwater in a single year, and is investing in wetland restoration and replenishment in key basins worldwide. Amazon aims to be water positive by 2030, funding projects that will return nearly 1.85 billion gallons of water annually to watersheds in Brazil, China, Chile, and the U.S., and supporting conservation along Chile’s Maipo River. Dow’s Terneuzen facility in the Netherlands reuses 2.5 million cubic metres of water per year, cutting energy use by 96.5%. These are just a few examples of how industry can drive innovation, reduce stress on aquifers, and set off a ripple effect of water security for communities.
What all these examples prove is that when the conversation shifts from scarcity to solutions, governments and industries step up. Singapore’s “Four National Taps,” Hong Kong’s multi-pronged management, Namibia’s pioneering reuse and aquifer recharge, Orange County’s groundwater replenishment, Dubai’s massive recycling push, and now the water positive movement in industry—all show what’s possible when we focus on what can be done, not just what’s missing. This isn’t just about supply. It’s about resilience, energy savings, and building a future that works for everyone, even as populations grow and the climate changes.
Those of us building, running, and inventing the world’s water systems have a unique responsibility. Every time we pitch a new project, share a success story, or talk to policymakers, we’re shifting the focus from limits to possibilities. Water abundance isn’t a fantasy, it’s a choice. The more we talk about what’s working, the harder it becomes for officials to hide behind old excuses.
This isn’t just PR. It’s about creating the momentum and political will we need to get things done. When industry, the public, and the media all speak the language of solutions, real change follows.
Let’s Be the Voice of Solutions. Let’s stop being the echo chamber of crisis. Let’s become the megaphone for answers. The technology is here. The models work. The need is urgent. If we change the conversation, we can unlock the political will and alignment needed to deliver water security for all. The era of water abundance is within reach. Let’s lead the way, and make it happen.
