The International Rainwater Harvesting Alliance (IRHA) promotes rainwater harvesting as an effective and sustainable solution in the face of water shortages and floods, while supporting ecosystems and communities.
IRHA was created in Geneva in November 2002 following recommendations formulated during the World Summit for Sustainable Development in Johannesburg two months earlier. The mandate called for the federation and unification of the disparate rainwater harvesting (RWH) movement around the world, to promote rainwater as a valuable water resource and to build on achievements in this field for the fulfilment of the Millennium Development Goals.
