By 2050, rising seas could salinize freshwater for 1.8 billion people and EU river flows may drop 10% to 40% in southern regions, turning supply planning into a climate bet. At the same time, smarter operations are already cutting waste, from AI leak detection that prevents 20% to 30% of water loss to wastewater treatment upgrades that use about 0.5 kWh per cubic meter. How close are we to bridging the gap between accelerating risks and measurable efficiency gains across the water industry, and where do the biggest surprises hide?
