---------------------------------------------------------------------***--------------------------------------------------------------------An economic feasibility of project is worked out by Abstract - Wakurde lift irrigation scheme is under Maharashtra Krishna Valley Development Corporation (MKVDC). A scheme is located in Wakurde of Sangali district, Maharashta State, India. It is major ongoing irrigation project of Krishna basin basically implemented for irrigating areas of Shirala and Valava Tal. in Sangali district also Karad Tal. in Satara district. Techno-economic viability of project is one of the important key factor having significant contribution in success of lift irrigation scheme. The aim of this study is to check economic feasibility of LIS and asses it’s social impact, as it is important to know that whether the project is beneficial or not. For this purpose, we calculated the economic feasibility and sanctioning of projects by working out benefit to cost ratio and Internal Rate of Return (IRR). The purpose of this study is to overcome problems is execution and cost-time overruns. We assessed actual facts and problems in implementation of this LIS. We also studied practical irregularities while running this scheme. In this study suggestions are given to improve efficiency of project and to overcome actual on field problems. Key Words: MKVDC, economic feasibility, socio-economic impact, Lift Irrigation System, cropping pattern, benefit to cost ratio. 1. INTRODUCTION Wakurde Lift Irrigation Scheme is under Warana Irrigation Project which is located on Warana River in Krishna basin. It is proposed to lift water from (LBC) Left Bank Canal of Warana project. It consists of main 2 parts and again first part divided into 3 stages and second part is divided into 2 stages. As per the original standard approved by the Corporation in 1998, it was planned to irrigate 15775 hectares of irrigated area by pumping water in one area in 3 phases. As per the proposed second RAA of this scheme, a total irrigated area of 28,035 hectares is proposed to be irrigated as 12,275 ha in 3 phases under Part 1 and 15,760 ha in 1 phase under Part 2. Total cultivated command area of Wakurde LIS project is 33,062 ha. Out of that irrigable command area is 28,035 ha. The crop structure proposed in the first RAA approved was 126% and 123% for Sangli East and Sangli West respectively. It had 20% cane crop for both the regions. According to the proposed crop structure, 173.36 gallons of water is required for Modified Penman method for irrigation. © 2024, IRJET

Benefit to Cost ratio (B/C ratio) and Internal Rate of Return (IRR) methods which are considered as economic analysis methods. 1.1 Necessity India’s ultimate irrigation potential is 140 million hacters but only 87 million hacters is utilized through major, medium, minor irrigation project and ground water. This gap can be reduced by using irrigation system of higher water use efficiency. The conventional method for conveying water for irrigation in India has certain limitations as evaporation losses, seepage losses, land acquisition and thefts. In order to overcome these drawbacks, pipe distribution network system is best alternative. It is necessary to search innovative alternative for modernization of existing water distribution network system. There are various irrigation methods available but an importance of ‘Lift Irrigation Scheme’ is unique. The total 8% LIS of Maharashtra irrigates 22000 ha of land which finances Rs. 6462.5 million. Basically, lift irrigation schemes are used to lift water from lower level to higher level mainly consists of water sources (such as dams, K.T.weirs, river canals), lifting medium and conveying medium. Dams and canals are constructed to increase irrigated area at lower level than dam level but scarcity of water remained the problem for higher areas. India is mainly an agricultural country and water resources plays vital role in irrigation. Now a days, industrialization demands for more water availability which leads to reduce water available for irrigation. Stress due to water scarcity increasing day by day. To reduce this water scarcity and meet rapid water demand of irrigation, adoption of new irrigation methods is essential. Warna and Krishna rivers are two major rivers which flow in Maharashtra state and are linked together by Wakurde LIS in Tal-Shirala, Dist-Sangali. 1.2 Project Details An original administrative approval of the project, the first Revised Administrative Approval (RAA) and proposed administrative approval details are as follows:
