International Rainwater Harvesting Alliance (IRHA)

The IRHA contributes to promote rainwater as an effective solution in the face of lack of water, natural disasters (floods and droughts), which weaken the ecosystems and expose everyday thousands of women and children to greater vulnerability. IRHA is an organization governed by Swiss law and recognized as being of public utility with ECOSOC status.


Who we are?

The International Rainwater Harvesting Alliance (IRHA) is an NGO established in Geneva since 2002 and specializing in capacity building of communities and services in rainwater management, in support of low-income populations in developing countries. IRHA is a Swiss association recognized for public utility which received the UN ECOSOC status in 2010.
We intervene in the management of water resources, drinking water and sanitation services but also in the field of soil management to ensure healthy communities and ecosystems.
The IRHA was founded and taken over by experts who have dedicated their careers to the development of developing countries. Their ambition, always intact, is to articulate as part of their professional practice:
- their commitment to harmonious and sustainable development,
- the expertise acquired during their professional practice,
- the efficiency, responsiveness and independence provided by a human-sized NGO.
IRHA encourages the implementation of concrete, effective and innovative solutions to strengthen communities' resilience and adaptive capacity to climate change.
