Abstract:
Water is one of the most important natural resources and all forms of life are dependent on it. Rainfall in drought prone area is highly erratic storage must be an integral part of any rainwater harvesting system. Plastic lined farm pond is the best option for providing supplemental irrigation and to enhance productivity. The present study consists of three parts. Estimation of peak runoff rate, estimation of runoff volume, estimation of cost of plastic lined pond for different capacity. These scrutinized data were then grouped into weeks (total 17 weeks) and finally two days maximum rainfall values were selected from each week. We designed plastic lined pond of 2000 m³ capacity for catchment area of 30 ha, 40 ha, 50 ha, for which values of estimated peak runoff rate were 4.62 m³/sec, 5.73 m³/sec, 7.77 m³/sec and volume of runoff were 4.137 ha-m, 5.512 ha-m, 6.890 ha-m respectively and total cost for design of plastic lined pond rates as per BSR, 2013-2014, Panchayat Samiti, Girwa (Udaipur) was Rs. 5,88175. All in all, considering the benefits accuring from the implementation of the project and during the life time of the structure (10-15 years) it can be safely said to be beneficial.
