MEIL's Engineering Marvel Converts Telangana's Dream Into a Reality
HYDERABAD, India, August 12, 2019 /PRNewswire-AsiaNet/ --

Constructs World's Largest Lift Irrigation Project: KLIP – Laxmipur Underground 
Pumping Station 

Megha Engineering and Infrastructures Limited (MEIL) has unveiled yet another 
pivotal moment in the Kaleshwaram Lift Irrigation Project (KLIP). MEIL 
successfully commenced operations in the world's largest Laximpur underground 
pumping station (LUPS - The Package 8). The pump house named after the goddess 
Gayatri, successfully completed the wet run on Sunday night, 11th August. The 
wet run began with switching on the 5th machine in LUPS. With this, around 3000 
cusecs of water rose to the top of 111 meters and flew into Mid-Manair through 
the gravity canal. The gush of water from the underground impressed the 
onlookers. The Chief Minister of Telangana Mr. K. Chandrashekar Rao is expected 
to inaugurate this colossal pump house on Wednesday.


The longstanding dream of Telangana, a dryland area in South India is now 
turning out to be a reality with this project. The LUPS would enable live 
storage of water in reservoirs throughout the year in the Godavari River Belt. 
This colossal pump house, considered as the heart of KLIP, is an outstanding 
engineering marvel as it is the world's largest underground pumping station 
constructed 470 feet below the earth's surface. This unique pump house would 
enable reverse pumping of Godavari water into the same river, thus rejuvenating 
the hitherto dry areas en route.

Describing the Laxmipur Underground Pumping Station, Mr. B. Srinivas Reddy, 
Director, MEIL, said, "This is an extraordinary underground pumphouse, 470 feet 
below the ground with twin tunnels and the largest surge pools in the world. 
This is an ultra-mega project in the world, having 7 motors, each having a 
capacity of 139 megawatts. These motors can lift 3 TMC of water per day. This 
is the true example of 'Make in India' as these gigantic Motors are developed 
in the country with the computational fluid dynamics (CFD) technology. The most 
significant feature of KLIP is that it completed the construction of electrical 
infrastructure with 3057 MWs capacity that comprises six 400KV and 220KV 
substations, transformers and 260 kilometres of transmission lines, 7 
kilometres of 400 KV XLPE under ground cable. In any parameters, this project 
is the world's most innovative mega project. And the credit goes to MEIL for 
accomplishing this gigantic task."

The structure and size of this underground work is simply mind-boggling. Going 
around the pumphouse will remind one of visiting a huge underground shopping 
mall with multiple floors. Generally, pump houses for lift irrigation projects 
are built at ground level near river banks to pump water to a higher elevation. 
However, this unique super structure, the first-of-its-kind in the world, is 
built at a location below the ground with a pumping capacity of 2 TMCs of water 
per day.

Massive underground caverns have been excavated to construct the pumphouse and 
surge pools to lift incoming water from underground. Pumps and motors are being 
erected to lift water from there. For this man-made engineering wonder based on 
scientific and technological grounds, 21.6 lakh CuM of soil has been excavated 
from 470 feet beneath the surface of the earth to build a power house by using 
4.75 lakh cubic meters of concrete.

Nowhere in the world, does such a huge cavern exist with a size of 140 meters 
depth, 25 meters width and 65 meters in height. PumpHouse Service Bay is 
located at 221 meters below the ground, while the pump bay is at 190.5 meters, 
transformer bay at 215 meters, the control room at 209 meters beneath the 
earth's surface respectively. The pumphouse consists of unique twin tunnels, 
built side by side. The length of each tunnel is 4,133 meters and the diameter 
is 10 meters. As each motor requires 139 MW of power to run, a 160 KVA capacity 
pump transformer along with compressor units have been set up successfully.

The most amazing part of this underground construction is the surge pools in 
the pump house. To ensure uninterrupted pumping, three surge pools have been 
built to store enough water. Erection of turbine pumps at a depth of 138 meters 
underground is another unique feature of the project. Each motor pump weighs 
around 2,376 metric tonnes and one can imagine the massive size of each pump 
unit. For this reason, these motors are called as 'Giant motors'.

Megha Engineering Infrastructure Limited (MEIL) with 30 years of its rich 
technical expertise in such complex and high-end electro-mechanical works has 
been executing this project as a mission with an objective to deliver water to 
the farmlands in time and quench the thirst of Telangana. 

"We feel honoured to be a part of Telangana's dream project and the world's 
biggest lift irrigation project, the KLIP. It has been a privilege and a 
lifetime opportunity to execute with world-class technology by coordinating 
with the world's best engineering suppliers and realising the water dreams of 
Telangana. The Chief minister Mr. K Chandrashekhar Rao's determination, 
continuous supervision, consultations and his encouragement to project site 
engineers enabled us to complete the project in time," said B. Srinivas Reddy, 
Director, MEIL.
