What is Kaleshwaram Project?
The total length of Kaleshwaram project is approximately 1,832 kms, of which 1,531 kms is gravity canals and 203 kms comprise water tunnels. There are 20 water lifts and 19 pump houses in the project. The massive project is divided into seven links and 28 packages and involved digging of 20 reservoirs in 13 districts with a total capacity to store 145 TMC. The reservoirs are interconnected through a network of tunnels running about 330 kms, the longest underground tunnel is 21 kms long connecting Yellampalli reservoir with Medaram reservoir.
While the intricate canal network covers approximately 1,832 kms, the farthest point is Narketpally in Nalgonda district which is 500 kms away from the source.
What is the reason of building this project ?
The project had to be built at such a size and scale because while the Godavari flows at 100 metres below Mean Sea Level, Telangana is located at 300 to 650 metres above MSL.
Except for pumping water using gigantic pumps with mindboggling capacities, there is no other option, according to officials. The project is all set to create a world record in July when seven gigantic pumps with a capacity of 139 MW each in a pumping station built 330 metres below the surface will start lifting 2 TMC of water per day received from Medigadda Barrage on Godavari through a 14.09 kms long underground tunnel, the longest irrigation tunnel, in the world. The pumps would be operating at a cavern and surge pool which also holds a record for being the biggest in the world with a capacity to hold 2 crore litres of water.
