Worldwide, 2 billion people do not have access to safe drinking water. An estimated 3.6 billion people do not have access to adequate sanitation. In 2021, more than 50% of schools will not have soap for good hygiene (WHO/UNICEF, 2021).


The challenge of providing access to safe water for all


Access to safe drinking water and adequate sanitation is a human right and can prevent a significant proportion of water-related diseases. To date, 86% of urban residents have access to safe drinking water services, but only 60% of rural residents. Safely managed sanitation services reach 62% of the world's urban population, but only 44% of the rural population.

Rainwater is a free resource that can play a vital role in the realisation of this human right. Improving the management of this resource is a highly relevant and effective response to improving the health of children, women and communities around the world.

As such, the management of this resource is fully in line with the Sustainable Development Goals (SDG) 6.

In order to guarantee access to rainwater resources for all and everywhere, IRHA intends to support

  • Strengthening community access to safe water and sanitation services and good hygiene practices through the implementation of sustainable and operational rainwater harvesting systems, sanitation (latrines, toilets) and hand washing.
  • Strengthening the knowledge (technical and organisational capacities) of local actors in terms of prevention of waterborne diseases, maintenance and sustainable management of infrastructures.
  • Supporting local actors to improve rainwater management and to implement natural resource conservation initiatives in their territories.

"Thanks to the Calabash, my wife was able to cook and wash without using tap water. There are many of us in the household and water bills are expensive. Thanks to this rainwater harvesting system, instead of paying 6,000FCFA every two months, I only had to pay 1,500FCFA. "
