The rain water harvesting and water scarcity are two opposite extreme end products of adequate management and un-scientific planning of ground water renewable resource in specific geographic area / river basin / hydrological unit, respectively. It has been influenced with potable nature of water under different water utilization categories namely: Potable, Semi-potable and Non-potable. The potable water is being utilized for drinking, irrigation of food crop and cultivation of fruit / vegetables. The semi-potable water has utility in municipal supply, washing, bathing, cleaning, and sanitization of street / road and gardening / lawn maintenance. The non-potable water has industrial application, construction activity with BIS Code provision, fire fighting, vehicle washing cum cleaning and dilution of sewage. The water scarcity is on account of excessive pumping out of ground water at alarming rate, leading to area as critical, semi-critical and over-exploitation category of ground water development stage [%]. It is required for meeting to the heavy demand under various water utilization categories [6]. The rain water harvesting has been common in developed to developing country including India. There is various rain water harvesting structures with proven capability for urban and rural area. These are discussed with quantification of rain water harvesting potential and cost estimate. The implementation of proper rainwater harvesting with holistic approach has great significance towards ground water conservation including mine water locked up in old workings of coal and lime-stone deposit.
