Because of the growth in the demand of fresh water driven by growth in the global population and of the economies, the world may see more than six fold increase in the number of people living in the condition of water stress from 470 million today to 3 billion in 2025. Hence in order to harness and meet our daily demand of water requirement, one need to think of alternative cost effective and relatively easier technological methods of conserving water. Rain water harvesting is one of the best methods fulfilling those requirements. As entitled the rainwater is harvested and recharged in the LDRP-ITR campus. Rainwater harvesting potential of whole campus was calculated and based on it, various alternatives of harvesting the rainwater and their respective costs were thoroughly studied. The best alternative was selected and thereby implemented in the LDRP-ITR.
