The global warming is todays burning issue all over the world at present India is also facing the same from last few decades. In India drought full conditions arise by reason of global warming affect, unsuitable rainfall distribution as well as local geological and geomorphologic problems. The study area goes through drought like condition during summer season. The heavy rainfall in study area is not effective to recharge aquifer because of unsuitable geology (Hard compact rock layer at shallow depth). Direct aquifer recharge by implementing rainwater harvesting during rainy season possibly the complete solution solves this critical issue. Rainwater harvesting, the process of collection, conveyance and storage having diachronic birthright can be served as better solution for this problem. In the era of urbanization and industrialization, installing high tower building and paving surface is a part of style. But this is resulting in a huge problem of replenishment of ground water. Ground water recharge by rainwater harvesting stands as a best solution for the problem. The main objective of this paper is to design economic model for rainwater harvesting. Current project implemented surroundings of bore well in the premises of government school of Goregaon village of kokan region, dist. Raigad. The geological investigation of study area confirms that existing geology is unsuitable because of very low percolation rate to recharge aquifer and operate as perennial source. It is also observed that the water quality aspects dont stand to fulfil water standards of World Health Organization. An integrated planning has been done in order to recharge the confined aquifer by rooftop water. This study gives innovative planning and design to enlighten quality and quantity of ground water by using economic material such as gunny bags and geo-membrane. However, the environmental benefits of ground water recharging with less installation cost and better quality water gives new direction to such projects.
