International Rainwater Harvesting Alliance

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.

Countries of Operations

IRHA develops projects in areas where the needs are felt, where the conditions for long-term work exist and where we have local partners, who are solidly anchored locally and capable of ensuring the sustainability of investments.

IRHA has developed strong relationships with a network of national rainwater organisations (Alliance) with whom we maintain close links, particularly for advocacy and policy making.
