POTENTIALITY OF RAINWATER HARVESTING IN DANGE COLLEGE CAMPUS OF HATKANANGALE FOR SHRINKING THE WATER SCARCITY
Harvesting the rainwater for the water conservation and fulfilment of water requirements in the micro level areas with the optimistic method is essential in for better future. Thus the present research aims to identify the potentiality of rainwater harvesting in Dange college campus of Hatkanangale for shrinking the water scarcity.The campus located in rain shadow zone of Western Ghats receives 820.4mm annual average rainfall. It has 4.5 acres of campus with 6090 sq.m. built up area and 2547 sq. m. area of the roof surface. College has 6070 sq.m. area of fruit garden and 7100 sq. m. Play ground. For the present investigation, data regarding various aspects are collected through the college administration office, and skymet website. Runoff Coefficient and Annual rainwater harvesting potential (ARHP) of the campus is estimated by using formula (ARHP = R x AC x RC) given by Pecey, et.al; 1989. The analysis revels that approximate of 75 Lakh Litre water will be collected from the whole campus. Out of that 18.80 Lakh litre water will be collected purely on rooftop of the building and it is directly usable for the drinking and sanitization. It will be fulfil 90 % demand of the fresh water. Out of 74.52 Lakh litre water 55.71 L. Litre water will be useful for the gardening in the dry season.
