ABSTRACT
With the growing importance and energy efficiencies technology of network facility there is an urgent need to integrate the new knowledge in these fields into our living life system. This is rain water harvesting which is very very important in now a day’s crisis of water resource, management of dally requirement of our usable water and simply say the wastage of valuable water. There are three important arguments in support of 3R,, 1. Climate change adaptation. 2 Recirculation in the water chain 3. Green water management. However water reuse is good for growing crops or recharging aquifers or somehow its very urgent of life. Everybody we know from our childhood that another name of life is water, without water man can’t survive, can’t continue to live or exist, especially in spite of danger or hardship, continue to live or exist in spite of hour not even a day. In a human body the volume totals of blood suspension heterogeneous mixture that contains solid particle plasma 2.7–3.0 liters (2.8–3.2 quarts) in an average consciousness to know that it is essentially an aqueous solution containing 92% water in a human body 8% blood plasma proteins, and trace intact of other materials. Now why rain water harvesting and how rain water reinvesting? Rainwater harvesting (RWH) including best practices of using harvesting systems in urban areas for troubleshooting, and advice about tanks and systems and sourced from where and reuses for life & live. We here discuss widely use for residential and some industrial applications that collated rain water process of gathering, then conduits through pipe thereafter the action or method of storing something for future use. After filtration with the help of photovoltaic pumping system we can store good quality water in this retention and safe keeping water from rain water we be able to complete a circle of aquatic resource life like drinking, washing, plantation, cooking, cultivation and balancing ecosystem.
