Studies on determination of purity of harvested rain water & non harvested ground water: bacteriological assay

All over the country Rain Water Harvesting has been made mandatory since 1996 as over extraction of ground water and wastage of rainwater have led to severe water crisis. Hydrogeologists says that, it makes ecological and financial sense to harvest rain water or roof top water, for short term use and long term improvement of the water table. It is in Delhi, Andhra Pradesh, Chennai, Kerala, Maharashtra, Gujarat and Madhya Pradesh where its implementation has become successful in water conservation. Kada is a village which lies in district Beed of Maharashtra, and is famously known as a strong drought prone area. It is in this concern, present studies have undertaken for conservation of natural rain water and its storage in surface water or in tubewells. By constructing Rain Water Harvesting systems at five different locations in Kada, which includes schools and public places. Researcher has found successful rise in water levels of borewells and people are enjoying the results. The researcher tried out to find the water quality and its purity of harvested rain water as well as non harvested ground water. Researcher assessed potability as per IS 15200 for drinking water quality assessment, and comparative studies have shown that water gets more purified naturally when rain water is harvested.
