The International Rainwater Harvesting Alliance (IRHA) is a Swiss non-governmental organisation based in Geneva since 2002. IRHA’s mandate is to promote rainwater as a sustainable solution to water scarcity, natural disasters that undermine ecosystems and communities.

Our work is based on the implementation of rainwater management projects in developing countries where access to clean water and vulnerability to climate change are daily problems, directly and negatively impacting the lives of thousands of people.
