water harvested including all the sites was around 120565.045 m 3 . It is clear from the results that the water harvested with both conventional and Furaat system compared very well with respected to water collected. Major advantage derived from the Furaat rain water harvesting system was the treatment of water while conventional system results in more turbidity and suspended solids including poor quality of water. With respect to Furaat system rain water gets treated on its way in to the aquifers. This system provides fool proof dual treatment of the rain water. As such quantity of water harvested by both the new technique and conventional one doesn't differ except for the quality of rain water harvested. Furaat system has helped in the recharging of tube wells without any pollution. This would help the people around the village to use the water from the tube wells for domestic and agricultural purposes. Ground water Ground water depletion and shortage of fresh water has made water management very critical issue for the development of country's economy. India is endowed with many large rivers, lakes and wells but they need proper conservation. This can be achieved by following rain water harvesting and conservation of every drop of water. In this context JK Lakhsmi Cement at Ahiwara has carried out an immense survey and came up with an efficient rain water harvesting system. A new patented rain water harvesting unit was developed and designed by Furaat Earth Pvt. ltd for rain water harvesting. Alongside conventional rain water harvesting was also carried out and the results were compared and discussed. Before initiating the rain water harvesting technology ground water level at 11 identified tube wells from upstream and downstream of the rain water harvesting unit installed were measured and the depth varied between 22 to 32 m during pre monsoon and between 9-20 m during post monsoon season. It is clearly seen from the result indicated in Table 5 and Table 6 the ground water level has considerably increased during post monsoon season after the installation of rain water harvesting un its. At these sites annual rainfall varied between 1150 to 1370 mm. Table No.5: Ground water level of the tube wells in study area before implementation of rainwater harvesting :.
