What to study?

For prelims and mains: key features and significance of the project.

 

Context: The world’s largest irrigation and drinking water system—Kaleshwaram Multipurpose Lift Irrigation Project—was recently inaugurated by Telangana Chief Minister K Chandrashekhar Rao.

 

What’s the project?

The Kaleshwaram project is an off-shoot of the original Pranahitha-Chevella Lift Irrigation Scheme taken up by the Congress government in 2007 when Andhra Pradesh was not divided.

After the formation of Telangana in 2014, the TRS government redesigned the project on the ground that the original plan had too many environmental obstacles and had very low water storage provision — only about 16.5 tmc ft.

After conducting a highly advanced Light Detection and Ranging (LiDAR) survey for a couple of months, the government separated the original component serving the Adilabad area as the Pranahitha project and renamed the rest as Kaleshwaram by redesigning the head works, storage capacity and the canal system based on the data of availability of water at different locations along the course of the Godavari and its tributaries.

 

Impact:

The Kaleshwaram project has provision for the storage of about 148 tmc ft with plans of utilising 180 tmc ft by lifting at least 2 tmc ft water every day for 90 flood days. The project is designed to irrigate 7,38,851 hectares (over 18.47 lakh acres) uplands in the erstwhile districts of Karimnagar, Nizamabad, Warangal, Medak, Nalgonda and Ranga Reddy.

 

What’s unique?

According to engineers, KLIP has many unique features, including the longest tunnel to carry water in Asia, running up to 81 km, between the Yellampally barrage and the Mallannasagar reservoir. The project would also utilise the highest capacity pumps, up to 139 MW, in the country to lift water.
