About 73% of the population is rural. The economy of the state is predominantly agrarian; agriculture contributes about 50% of the state’s income and employs about 70% of the work force. Since agriculture is the main activity and it has close links with the development in other sectors, for overall economic progress of the state, achieving faster agricultural growth is imperative. Therefore, there is an urgent need for increasing food and fiber production to meet the demands of increasing population as well as providing rural employment. Development of irrigated agriculture has played a major role in the economic growth and poverty alleviation through successive plan periods. These can be achieved by expanding and improving the irrigation sector, exploiting the considerable water resources, with which the state is blessed. Two major rivers of India, the Godavari and Krishna and their tributaries, flow through the state, providing irrigation. Farmers in Telangana mainly depend on rain-fed water sources for irrigation. Rice is the major food crop. Other important crops are cotton, sugar cane; mango and tobacco are the local crops. Telangana is situated on the Deccan Plateau, in the central stretch of the eastern seaboard of the Indian Peninsula. It covers 114,800 square kilometres (44,300 sq mi). The region is drained by two major rivers, with about 79% of the Godavari River catchment area and about 69% of the Krishna River catchment area, but most of the land is arid. Telangana is also drained by several minor rivers such as the Bhima, the Manjira and the Musi between the two rivers Godavari and Krishna. The Godavari River enters Bhadradri- Kothagudem district from JayaShankar- Bhupalapalli district and flows nearly 250 km across the district. Bhadradri- Kothagudem district is one of the "Coal mining districts of India". The district has the Singareni Colleries head town, Kothagudem which is also called "Coal town of South India." It is currently a part of the Red Corridor. Doli Gutta, at 965 m the highest Vol-I/Chapter-1: Introduction 1-1 WAPCOS Limited DETAILED PROJECT REPORT SITA RAMA LIFT IRRIGATION PROJECT (PHASE- I) point in Telangana, is located at the northern end of the district. In 2006 the Indian government named Khammam one of the country's 250 most backward districts (out of a total of 640). It is one of the districts in Telangana currently receiving funds from the Backward Regions Grant Fund Programme (BRGF). Bhadradri- Kothagudem, Khammam and Mahaubabad Districts are endowed with Agro climatic and soil conditions in which a wide range of horticulture crops like mango, banana, cashew, coconut, oil palm, cocoa, pepper etc. are grown. Production and distribution of various kinds of fruits, vegetables and flowers and their seeds are the major activities supported by the horticulture Department. The erstwhile Khammam district has only one major irrigation project namely Nagarjuna Sagar Project (NSP) and there are some medium irrigation projects like: I. Kinnersani reservoir II. Wyra III. Thaliperu IV. BayyaramV.Bathupally VI. Lankasagar VII. Mukamamidi VIII. Pedawagu IX. Palair reservoirX. PalamVagu ProjectXI. ModikuntaVaguProject. Apart from these there are some minor irrigation tanks also available in the Bhadradri - Kothagudem& Khammam Districts. The combined irrigation potential of all these schemes is about 9.5 Lakh Acres out of about 16 Lakh Acres irrigation potential of the district. In order to harness the remaining irrigation potential of about 6.5 Lakh Acres and also to stabilization of some of the schemes suffering Ayacut, the present project “Sita Rama Lift Irrigation Project” has been formulated. 1.2 PROJECT RATIONALE Telangana is a semi-arid area and has a predominantly hot and dry climate and it has a skewed distribution of rainfall in space and time. Such situation has triggered exodus of people from rural area in search of livelihood towards urban areas. Statistics suggests that neither adequate concern nor due attention was paid in the past for the development of irrigation facilities in Telangana area. Due to long failure to harness the water resources potential for the area, Telangana is still remaining mainly as dry farming area and people are resorting to exploitation of groundwater for their irrigation needs. The use of Groundwater cannot provide a lasting solution because there is already over exploitation of groundwater. Tube-wells have not only gone deeper and deeper only but huge resources by the way of electrical energy are Vol-I/Chapter-1: Introduction 1-2 WAPCOS Limited DETAILED PROJECT REPORT SITA RAMA LIFT IRRIGATION PROJECT (PHASE- I) required to be employed for tapping the ground water. What is being exploited today in the name of water is the fossil water some over 15000-year-old heavily contaminated with fluoride and nitrate. How long this can go on? Because even if the state may have all money in the world to spend on this soon the underground water aquifers will exhaust. There has been general emphasis on gravity (flow canal) irrigation according to the command ground levels. However, very large command able area exists in the middle reaches of Godavari covering uplands of Telangana State spread over the districts of Rangareddy, Medak, Nizamabad, Karimnagar, Adilabad, Warangal, Nalgonda and Khammam where only lift irrigation is feasible. Most of these areas are backward and drought-prone areas as there is no permanent irrigation facilities even though there is adequate rainfall at some places. Most of the command area now proposed under this project is some of the balance command area not covered by any other major, medium and minor irrigation schemes in that vicinity. These command areas, even though fertile, are mostly upland areas which cannot be served by gravity. Hence, in order to provide dependable and permanent irrigation facilities, the only alternative left is to lift the water in stages near the vicinity of various patches of command areas. The transfer of water through lift schemes and conveying it to water deficient, upland regions of Telangana is thus of strategic importance and a pressing need toward a more equitable development of water resources for irrigation and other water requirements. Inview of above, earlier before the Bifurcation of Andhra Pradesh, two projects namely (i) Rajiv Dummugudem Lift Irrigation Scheme (ii) Indira Sagar Rudramkota Lift Irrigation Scheme were proposed in order to harness the irrigation potential of left out ayacut from existing irrigation schemes,
