| Abstract | The present study was conducted in four districts (Nagaur, Jaisalmer, Dausa and Baran) of Rajasthan, India during October, 2016 to March, 2017 to examine existing potential of RWHS’. The objective of this research are to Critically review the different RWHS’ and characterizing their suitability to different hydro-geological locations in the study area, Economic analysis of RWHS’ considering cost of structures and its perceived benefits and Evaluating the contribution of RWHS’ in ground water recharge. A total of 32 samples of Roof top RWHS’, 16 samples of Underground pits, 32 samples of Field bunds, 32 samples of ECD and 3 samples of Farm pond were interviewed with the help of detailed questioner. Furthermore 2 samples of Village ponds, 16 samples of Official underground pits, 32 samples of CCT and 32 samples of MPT were examined. A survey was done to check that ―why people adopt these RWHS’‖. The people of the districts which are in east side of Aravali range adopted these RWHS’ due to ―availability of enough fund to pay for initial investment on RWHS‖. And the districts which are in west side of Aravali range adopted these structures because they the potential of structure and they are really in need. Results prooved that larger RWHS’ are less expensive than small RWHS’, when taking into account investment cost, storage capacity and lifetime. In Nagaur and Jaisalmer districts domestic RWHS’ are satisfying the 26% and 35% of total drinking water requirements respectively. Among all RWHS’ which are used for agricultural purpose, Farm pond is more beneficial as it had lower payback period and higher contribution in productivity and farm income. Results also shows that targeting experienced farmers for the implementation of water harvesting structures would result in greater outcome. The status of ground water level was also improved due to RWHS’. These structures were constructed in May 2015 so in future these structures will contribute more in ground water level. |
