Keeping in view the available soil strata, average rainfall, rainfall intensity, social acceptability etc., a plan has been drafted to comprehensively utilize the rainfall water falling in the campus of Central University of Haryana, Mahendergarh, a campus of around 488 acres of area. Land area requirement for different suggested modes is likely to be a very small percentage of the total catchment's area.

Another objective of the study is that these recharge structures will serve as models and infuse confidence in people to follow the good work initiated by the Haryana Urban Development Authority.
