The International Rainwater Harvesting Alliance (IRHA) was created in Geneva in November 2002 following recomendations formulated during the World Summit for Sustainable Development in Johannesburg two months earlier. The mandate called for federation and unification of the disparate rainwater harvesting (RWH) movement around the world.
In partnership with the most eminent organisations and individuals in the field, the IRHA provides a lobbying and advocacy platform for RWH. It supports the growth of RWH solutions to water supply problems.
