It is high time now to fall for surface water usage instead of going for ground water resources to meet human demand on needs. Considered the main source of surface water, rainwater is deemed more or less as fresh, the cost of collecting rainwater too is very low. Rivers and canals, lakes and wetlands, ponds and dry wells. All are potential catchments to hold direct rainwater and its indirect source, the run-off storm water. The closed tanks also doubly work as settlement tanks to innately clearing the contaminated water to some extent. Pebbles, gravels, sand and charcoal. All available in abundance work great as natural filter for cleaning the rainwater before usage. Hence keeping an eye on the rapidly increasing day-to-day demand for water among fast growing human population, there lies a great opportunity to harvest rainwater to meet a potential scarcity and avoid destruction of the normal groundwater table level. The boon of rainwater harvesting is the unused or extra water which remains after using by the human settlements. It can be sent down to the aquifer to recharge the groundwater level too, so we are going to design an effective plan by collecting of rain water and recharging it, when there is shortage runoff water. Present paper majorly focuses on �ROOF TOP RAIN WATER HARVESTING� (RRWH) of the study area as �E.S COLLEGE OF NURSING �campus, Villupuram (near Vikravandi). The result analysis shows that the present RWH system is having the storage 32, 53,000 liters per year. The primary objectives are to fulfill the scarcity of the water in campus and then use it for the domestic purpose in college campus.
