Sankalpa Rural Development Society’s (SRDS) direct borewell recharge is an exclusive solution to revive dried up borewells. It is cost-effective and a permanent solution to replenish water in the underlying aquifers. With a 100% success rate, SRDS guarantees an effective solution for the farmers’ needs for ground water for agricultural purposes and other people’s needs for drinking water in urban and rural India.
In 2008 when Sankalpa Rural Development Society (SRDS) started their operations to recharge defunct borewells in Karnataka in 2008, the water shortage was acute. Almost 70% of the borewells had dried up in an area that received 997 cms of rainfall every year. The water table had sunk to 400 to 500 feet resulting in farmers selling off their lands to repay their debts, some even commiting suicide.
The organization has developed a solution that allows a direct borewell recharge with rain water harvesting. It is an effective solution for the farmers’ needs for ground water for agricultural purposes and other people’s needs for drinking water in urban and rural India. The solution includes a pond that catches rain water, filters it and channels it into the borewell. Recharging borewells and the underlying aquifer means an increase in the water table and therefore accessible water for agricultural purposes. Furthermore, the addition of rain water to the water table dilutes toxins such as high fluoride, as well as decreases the hardness of the water, thereby making it more potable. More than 1130 borewells have been sunk using this technology in seven states in India.
The technology implemented in this solution is not only improving the lives of farmers and other people in urban and rural india, it is also affordable. It requires 3 – 5 times less investment than for building a new borewell. The dilution of toxins and the decrease of hardness of water is a pleasant byproduct of the technology improving also the quality of drinking water. The technology helps farmers to move from harvesting 40% of the total land area to harvesting almost 100% of their land.
