Rain Bounty – District Rainwater Harvesting
Mazhapolima, District Collectorate, Ayyanthole P.O, Trichur District, Kerala State, India.
72% of regional households rely on dug wells which dry up in the dry summer season. Naturally the problem does not occur during the winter monsoon rains. Mazhapolima took up the challenge of finding ways to conserve monsoon rainwater in the wells. Using rain water also avoids other common quality problems like coastal saline ingress and high iron content in open wells.
Mazhapolima replenishes groundwater in dug wells by harvesting rainwater runoff from rooftops during the rainy season. Households install a pipeline in the roof directly connected to a well / borehole where they can store their water. This set up collects enough water to sustain their family throughout the dry season.
Participating households have found that ‘well recharging’ has put an end to water scarcity in the summer. To date, the project has installed over 30,000 rainwater collection and well recharging systems. Mazhapolima is now very busy installing new systems in response to strong demand, particularly in Trichur District.
Mazhapolima wishes to spread the good news throughout Kerala State, India and across the world wherever there is rain and dug wells. This simple, effective technique can help households guarantee a steady supply of clean water from their dug wells in any season. A WAFAward can showcase this technique at a global level to relieve the growing crisis of water scarcity.
