Rain water harvesting structures and utilization in the campus:
Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit (well, shaft, or borehole), a reservoir with percolation, or collected from dew or fog with nets or other tools. It provides water when a drought occurs, can help mitigate flooding of low-lying areas, and reduces demand on wells which may enable groundwater levels to be sustained. It also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts. The main purpose of the rainwater harvesting is to use the locally available rainwater to meet water requirements throughout the year without the need of huge capital expenditure. Rainwater systems come in all shapes and sizes, from simple catchment system under a downspout to large above and/or underground cisterns with complex filtration systems that can store thousands of gallons of water. In roof top rain water harvesting, which is low cost and effective technique for urban houses and buildings, the rain water from the top of the roof is diverted to some surface tank or pit through a delivery system which can be later used for several purposes. Mewar University has adopted this technique of rain water harvesting wherethe following activities are done by Universitytowards water harvesting and ground water conservation:
Three storage tanks of3938 cubic Ft., 2880 cubic Ft., 2394 cubic Ft and one well of 40 Ft. in diameter and 100 Ft. in depth are constructed at different areas in the University campus to capture the rain water and to minimize the water run-off. Rain water harvesting helps in recharging the gainers, improving ground water quality by dilution, improves soil moisture and reduces soil erosion by minimizing run-off water.
