Domestic Roof Top Rainwater Harvesting – A Case Study of Madgyal Village
Madgyal is a small village in India. Collaborative research was carried out in the village with the aim of developing and adapting affordable technologies for capturing and retaining rainwater runoff, including running from rooftops, which can serve as a valuable supplement to meet the water needs and households in a drought-prone area.
The research revealed the extent to which the adoption of adapted technologies could help greatly in conserving water resources in semi-arid regions in developing countries, while at the same time helping to alleviate poverty by improving the quality of life of women and children in these regions. It is envisaged that rainwater harvesting systems would enable poor households in a community to supplement their water supply needs and to also engage in backyard gardening, thus extending their cropping seasons through improved security of water resources and ultimately enhancing food security and contributing to poverty reduction.
The basis for this research was a socio-economic survey to obtain a picture of real-estate conditions and water demand in the area. Real estate was then classified in terms of water-harvesting potential.
- Data collection on water demand
- Data collection on real estate
- Quantified potential amounts of harvested rainwater for individual households
- Wide range of participation in the socio-economic survey
- Commitment of local people to implement the rooftop water harvesting system
- Number of households for which water scarcity has decreased
- Number of barrels installed
- Annual amount of harvested/stored water
Semi-arid areas where average annual rainfall is greater than 300 mm and drought periods are longer than 90 days can apply the methodology to calculate the amount of harvested rainwater per individual household. A socio-economic survey on household water demand should be carried out beforehand. There is no need for large investment or special education.
