Harvesting rain water is being followed in India since ancient times and our ancestors indeed perfected the art of rainwater management. Today rain water harvesting is being increasingly used in many of the Kerala apartments
. Not only in Kerala but the whole of India has been emphasizing on the use of this system to utilize water. There are a number of traditional methods of rain water harvesting. But many of these methods are dying slowly due to the onset of the modern techniques.
Kunds or Kundis is an ingenious method of rain water harvesting evolved by the villagers of Thar Desert to be used in the sandier tracts. It was developed basically to tackle drinking water problems. Kund is the local name given to the covered underground tank. Kunds are made up of local materials or cement and is more prevalent in areas where the groundwater is limited and is moderate to highly saline.
Kund is basically a saucer-shaped catchment area with a gentle slope towards the centre where there is a tank. The openings or inlets of the tank are guarded by wire mesh to keep away floating debris, birds and reptiles. A lid covers the top and water can be drawn out with a bucket. The catchments of the Kund are generally cleaned up meticulously before the onset of the rains every year. The proximity of a Kund to a house or a village saves the time and effort to search for drinking water. The Kund became an ideal service to collect drinking water with the benefits of cleanliness and quality of water.
