Kaleshwaram Lift Irrigation Project

[2] Currently the world's largest multi-stage lift irrigation project,[3] its farthest upstream influence is at the confluence of the Pranahita and Godavari rivers.

It remains untapped as its course is principally through dense forests and other ecologically sensitive zones such as wildlife sanctuaries.

[6] The project aims to produce a total of 240 TMC (195 from Medigadda Barrage, 20 from Sripada Yellampalli project and 25 from groundwater), of which 169 has been allocated for irrigation, 30 for Hyderabad municipal water, 16 for miscellaneous industrial uses and 10 for drinking water in nearby villages, with the remainder being estimated evaporation loss.

On 21 June 2019, the project was opened by Telangana Governor E. S. L. Narasimhan and Chief minister K. Chandrashekar Rao.

National Green Tribunal declared the Scheme is constructed without following the statuary provisions with regard to environmental aspects.

[7] Four major pumping facilities manage the project's outflow, the largest at Ramadugu (Medaram, Annaram and Sundilla being the others) is also likely to be the largest in Asia once consistent measurements are available,[8] requiring seven 140 MWh (500 GJ) pumps designed and manufactured specifically for the project by the BHEL.

Pressure Mains / Delivery Mains - 98 km Link-I: From Medigadda Barrage on Godavari River to Sripada Yellampalli Project Water will be reverse pumped from the confluence point of Godavari and Pranahita Rivers to Sripada Yellampalli Project with the help of 3 barrages (Medigadda, Annaram and Sundilla) and 3 lifts.

Link-II: From Sripada Yellampalli Project to Mid Manair Dam A new balancing reservoir is also being proposed in the outskirts of Hyderabad of 20–30 TMC to store water.

Assuming, on average, the pumps require constant running for two months during the monsoon period, 24 hours a day, the total electricity consumption would be 849 crore units.

80,000 crore, at an interest rate of 6% that needs to paid up over a period of 30 years, the annual loan repayment charge is about Rs.

A recent report by the comptroller and auditor general of India (CAG) has pointed out that the cost to benefit ratio of the project is 1:0.75 in contrast to the state govt.

Indian Public sector Enterprise BHEL is executing this project and has already commissioned 16 pumping units.

[15][16] In October 2020, the National Green Tribunal, India's court for environmental issues, directed the Telangana government to halt work on the KLIP except the drinking water supply component.

The National Green Tribunal has directed the Indian government's Ministry of Environment, Forests and Climate Change to constitute a committee to investigate the illegally granted clearances, and to file a report with them within six months.
