Design of on-farm reservoir for irrigation water supply in Karkata(Jharkhand, India)

This project tries to solve the water crisis that is suffering the village of Karkata, in Jharkhand, especially during the summer season. Getting a good understanding of the problem that most of the inhabitants of the village are suffering is the first and most important point that has to be reached, and this will be achieved by doing a visit to the village and undertaking several codesign workshops, a participatory technique that allows the requirements to be obtained directly from the main users so that they can remain at the centre of the solution. Once the problem has been defined, it is intended to design the best solution to improve this situation of water for irrigation at Karkata. For this purpose, the first thing that has been done is a detailed study of the physical characteristics of the area, a very important point since it allows us to better understand all its resources and how they can be sustainably exploited. In addition, a detailed study of the different crops has been carried out, mostly those which are available in the region, in order to obtain their water irrigation needs. As a result of all these studies, a first proposal of design is given in order to solve this problem, based on a rainwater harvesting system. In order to be a totally sustainable proposal and according to the villager’s capacities and needs, the design includes all the sizing of the installation for both the tank that is going to be used for storing the rainwater and the hydraulic and electrical systems. In addition to this study of the design, this project includes a detailed budget including consumables, permanent equipment and manpower, among others. It has been considered that the investment should be made to implement 2 tanks in different regions of Karkata, to be able to prove that the design works under different conditions. Although this budget may seem initially high, it must be taken into account that the Government of India is investing in the improvement of the conditions of farmers in the rural areas of the country. Specifically, Scheme nº6 of the Agricultural Engineering Schemes under Agricultural Engineering Department "Rain Water Harvesting and Runoff Management Program", provides benefits of 100% grants on the cost of works taken in land communities. That is why it is believed that when it comes to making this project, the fact of being able to benefit from the aid that the Government of India is granting is of great importance.Outgoin
