Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

Agriculture Rainwater Harvesting - Newsletter from International Rainwater Harvesting Alliance (IRHA)
The current edition of the newsletter features agricultural rainwater harvesting and how it can contribute to the world of farming. Posted on 11 May, 2010 04:50 PM

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, to promote rainwater as a valuable water resource and to build on achievements in this field for the fulfilment of the Millennium Development Goals.

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. It also provides a forum for its members to work together or share experiences, and thus for the benefit of people living with water scarcity.

Ensuring safe drinking water through innovative technologies to eradicate fluorosis - Sachetana Project - BIRDK and Govt of KarnatakaThis manual produced by BIRD-K and DRDPR (GoK) provides the details of the Sachetana project that aims to provide safe drinking water to fluorosis affected populations through the adoption of innovative technologies for rainwater harvesting and groundwater recharge.

The project is being implemented through the Gram Panchayats of 60 villages from 4 taluks among three districts of Karnataka state over a period of five years (2006-11).

The objectives of the project include:

  • Provision of safe drinking water through innovative rain harvesting structures
  • Recharge of groundwater through excavation of percolation ponds
  • Recharge of existing bore wells and direct recharge of aquifers
  • Awareness generation activities to promote sustainable management and management of water resources and water harvesting structures.
