Innovation Beyond the Obvious

The next wave of water solutions goes past finding new sources — it rethinks how we use and reuse every drop:

• Direct potable reuse — treating wastewater to drinking-water standards, already running in Singapore and Windhoek, Namibia.
• Precision agriculture — drip irrigation guided by soil sensors cuts farm water use by 30 to 50 percent.
• Graphene membranes — next-generation filters that could cut desalination's energy use by up to 20 percent.
• Managed aquifer recharge — deliberately refilling underground aquifers in wet periods to buffer against droughts.
