Goal 4 of 12

Safe water sources

Renewables-powered desalination and rainwater for all

Addu will secure its long-term water supply through five diversified sources — desalination, household and community-scale rainwater harvesting, responsibly managed groundwater, reclaimed wastewater, and mineralised bottled water. Solar PV and battery storage will support reliable desalination. Expanded rainwater systems will capture and store rainfall for domestic and public use, while carefully managed groundwater will provide a dedicated supply for gardening and landscaping. Expanded sewerage networks and advanced wastewater treatment will enable reclaimed water to be used safely for agriculture, irrigation, landscaping, and other non-potable purposes. Addu will also support the local production of mineralised drinking water in reusable glass bottles and large-volume containers for homes, restaurants, hotels, offices, and other businesses.
