The Challenge

In Cambodia, climate-related disasters are becoming more frequent and are making water stress worse. Droughts deplete water resources and floods pollute them. As these crises intensify, water scarcity harms health and hygiene and deepens inequalities. Children and vulnerable people are hit hardest. Schools, health centres and households all need a safe and reliable water supply.

What We Do

Build up knowledge of water management in the area, and develop an action plan with local authorities and communities.
Build rainwater systems for schools, health centres and public supply: 27 public systems of 30 m³ and three large-scale drinking water networks.
Equip households with 250 rainwater tanks of 8 m³ and build 200 sanitation facilities.
Install 105 infiltration and aquifer recharge systems.
Support local business owners to supply rainwater harvesting systems and services.
Run more than 30 training courses, and raise awareness among authorities and communities of sustainable rainwater management.

Progress So Far

The project was launched in 2025, alongside Rain Communities Sri Lanka.
to verify: first activities and results, to add when Rainwater Cambodia reports.

Expected Results

Local authorities lead efforts to improve access to drinking water.
Water is secured, in quantity and quality, for schools, health centres and households.
Local businesses offer rainwater harvesting systems and services.
Communities have stronger knowledge and technical skills.
More than 20,000 people benefit, 40% of them women.
