Across Asia-Pacific, water resilience is becoming a technology stack. Cities are modernizing pipes and sewers, countries are digitizing irrigation, and mountain regions are using satellite data, machine learning and early-warning systems to track water risks before they become disasters.
This week's signal is that water technology now spans the full resilience cycle: producing and reusing water, saving it through smarter irrigation, monitoring dangerous lakes, digitizing water governance and adapting urban systems to climate stress.
India and ADB have signed a $230 million project to modernize Chennai's water supply and sewerage systems, adding real-time monitoring, data-driven operations and faster sewer blockage detection to strengthen urban climate resilience.
INDO WATER 2026 is positioning advanced treatment, industrial wastewater, purification, reuse, smart water systems and irrigation technologies as part of Indonesia's wider push for urban sanitation and water-sector resilience.
Kazakhstan plans to commission around 1,000 kilometers of canals in 2026 while expanding water-saving technologies and canal digitalization, linking irrigation modernization with water security under rising scarcity.
PUB is testing ceramic membrane technology at Tuas that could halve the energy used to pre-treat seawater for desalination, making water production more efficient while strengthening resilience against algae blooms, oil spills and climate-related disruptions.
Tajikistan is implementing the automated THAW tool, which uses Sentinel-1 SAR satellite data and Google Earth Engine to detect newly formed or anomalously changing mountain lakes that may require closer GLOF monitoring.
Viet Nam's irrigation sector is moving from manual operations toward intelligent management, with AI, IoT, big data, GIS and digital twin tools supporting drought, flood and salinity warnings as part of climate-adaptive water governance.
