It is going to be inaugurated on 21st June. Megha Engineering and Infrastructure Limited (MEIL) has completed on a FastTrack mode and the construction has been completed in record time. All the civil and electro-mechanical works in Medigadda to Mid-Maneru link-1 and link-2 has been completed.

Leading the industry with decades of experience, the company installing 105 Machines out of 120 machines and constructing 17 pump houses out of 20 in entire KLIP. Medigadda, Annaram, Sundilla (link 1) pumphouses along with the world’s biggest pumphouse at Lakshmipur (Pakage 8 in link 2) are ready for pumping water. This prestigious Kaleshwaram Lift Irrigation (KLIP) Project would cater irrigation water to 37.08 lakh acres of land; another 18.82 lakh acres of command area will be stabilized with it.

On asking about this achievement,, Mr B Srinivas Reddy, Director, MEIL, said,” It has a privilege and lifetime opportunity to be able to bring the plan from print to reality. We have successfully engineered the world’s biggest pumping scheme in India. To achieve that, we used world-class technology involving the best agencies that have delivered quality. We at MEIL believe that quality and timely delivery of projects are the benchmarks to our success.”

“This is by far the first of its kind and the largest lift scheme in the world. The project requires 7152 MW of electricity to pump 3 TMCs of water daily. In the first phase, 4992 MWs of electricity is being used for pumping 2 TMCs of water.  MEIL has proven its strength in diverse forte – from the construction of major pump houses and power transmission infrastructure through to and civil and electro-mechanical engineering works at their best for pumping water this season,” he added.

Till date, the biggest lift schemes in the world were The Colorado lift scheme in America and the Great Manmade River in Egypt. The capacities of these schemes are in horsepower and they took over 3 decades for completion. Now, the Kaleshwaram Lift Irrigation project, an Indian Lift Scheme has become the world’s biggest in terms of capacities. Many other lift irrigation projects have also been completed and maintained by MEIL across India. The Pattiseema project in record-breaking time and got a place in “Limca Book of World Records” for that achievement. It also completed Handri-Neeva lift scheme in 2012 and maintaining it without any single problem ever since.

 

Records galore in Pump Houses

A total of 43 machines are being established for Medigadda, Annaram and Sundilla Pump Houses, each having 40 MWs capacity.  These three pump houses consume nearly 1720 MWs of electricity. The underground pump house in the package-8 will have 7 units, out of which 5 machines are ready to pump 2 TMCs of water per day. Each one of these machines is having the world’s biggest pumping machines with a capacity of 139 MWs. This underground pump house itself would consume 973 MWs of electricity. MEIL is also establishing four machines in Package -11, each with a capacity of 135 MWs. Four machines each with a capacity of 106 MW are being installed in Package -10. And another 7 machines, each with a capacity of 124 MW are in Package-6.

During 2018-19,  the amount of work completed is really a world record in terms of execution in pump houses. Nearly 177 Lakhs CuM worth of earthworks were completed for Medigadda Scheme. On average, meil completed one lakh CuM of earthwork per day.  In the same way, 8.62 Lakhs CuM of concrete work was completed in just 22 months. Completing 1310 CuM of concrete work for a lift scheme and laying 39700 tones of underground pipes in 18 months is another distinction. MEIL established 6 machines at Medigadda in just 10 months, which is the shortest time frame in the world. 

Package-8 Pumping Station: A Marvel in underground engineering

The Package-8 pumping station can lift 3 TMCs of water per day. It is constructed 330 meters below the ground and is the only one consisting of such a gigantic underground pumping station with 7 units, each having a capacity of 139 MWs.

The depth of the pumping station was calculated based on various technical and scientific parameters. The machines supplied by BHEL are developed with robust engineering and computational fluid dynamics (CFD) technology which helps in overcoming even complex situations.

 “The uniqueness of this pump house lies in its twin tunnels, which have been constructed side by side by excavating the earth with a diameter of 10.5 meters, each having a length of 4133 meters. Surge pool and additional surge pools of this pump house are also the biggest in the world. This is the first time such constructions have been made under the ground. One can imagine the size of the Pump House that has 330 Mts depth, 25 Mts width and 65 Mts of height,” said Mr Srinivas Reddy.

Unique Power Infrastructure

Nearly 7152 MWs of electricity is required for lifting 3 TMCs of water per day.

Gayathri Pump House (4)

The magnificent scene of water pumping from Gayathri Underground Pumping Station of Kaleshwaram Project is appealing to all the eyes; water is rushing through the mega pumps as if the mother earth is releasing all the water at once, so as to wet the thirsty barren lands of Telangana farmers.  Flowing through the canals, this Godavari water is reaching Mid-Maneru reservoir that is already drawn a fresh look with filled water. An exceptional technological wonder created by Megha Engineering and Infrastructure Limited (MEIL) was commenced on 11th August and ever since pumping is being uninterruptedly from this underground pumping station.  The pumping capacity of machines is being increased in a systematic way, as already 4 machines were functioning lifting 15,000 cases of water on an average per day. As part of the first phase, 5 machines were installed in this pumping station with a capacity of pumping 2 TMCS per day.  

 This world’s largest underground pumping station, named as Gayathri (Laxmipur) Underground Pumping station has supplied nearly 11.40 TMCs of water to Mid Maneru in 22 days of its operation, with the help of 3 Machines;   The first initiated 5th Machine has continuously worked for almost 380 hours over 16 days, while the 2nd machine was operated for 378 hours. Each of these two machines has pumped 4.80 TMCs of water on average.  The 3rd machine which got into operation 10 days after the first two machines, has pumped 2.80 TMCs of water by working for 248 hours.  All this water pumping is being done from 470 feet below the earth.  This ‘world wonder’ underground water pumping station constructed all along with a length of 327 meters,  has 5 machines in total, each with a capacity of 139 MWs.  Work for installing another 2 machines are going on, a war footing note. Among these two, one machine has already completed its dry run. 

 Dispelling the apprehensions of cynics that there would be many technical and operational issues with this gigantic pumping station, Gayathri underground pumping station has been operating very smoothly since its inauguration. Performing wise it is breaking all the records set by MEIL itself in its various other projects located in various parts of the country. Pattiseema project which has got so much attention with its linking of Godavari and Krishna Rivers had 24 machines in total and so far it could pump 289.8 TMCs of water, since its inauguration in 2015.  MEIL has got the recognition in Limca Book of Record for its meticulous execution of this project.  In 2018, this project has worked for 76,068 hours pumping 96.94 TMCS of Godavari water into Krishna River.  In 2019, it has pumped 27.22 TMCs of water by working for 21.356 hours (till 31st August 2019).

Lakshmi Pumping Station at Medigadda was inaugurated on 21st June by Chief Ministers of Telugu States, K. Chandra Sekhar Rao and Y.S. Jagan Mohan Reddy, which is instrumental in lifting the water from Pranahitha.  The six machines installed here have worked for 1595 hours in 36 days pumping 12.20 TMCs of water in total.  The 6th machine inaugurated by Chief Ministers worked for 367 hours in 22 days lifting 2.80 TMCs of water.  Rest of the machines are also working efficiently without any disturbance.  The lately started 2nd machine has pumped 0.27 TMCs of water so far.

 Saraswathi Pumping Station at Annaram with its 6 machines has pumped 4.86 TMCs of water in 16 days working for 461 hours in total.  The 1st machine has provided 1.70 TMCs of water to Sundilla Reservoir in 8 days by working 161 hours.  The six machines at Parvathi Pumping Station located at Sundilla which provides water for Yellampalli Reservoir and connects Link 1 and Link 2 of Kaleshwaram Project have worked for 23.67 hours in 11 days.  But as Yellampalli Reservoir is already filled with Godavari flood water, the capacity utilization of this pump house is not being utilized to its full extent. 

 MEIL has got a distinct identity by installing such a massive pumping house for lift irrigation projects. Gayathri Pumping Station is the biggest among all the pumping stations constructed by this company. So far HandriNeeva project is considered to have biggest pump houses in which 12 pump houses were constructed in 1st phase and 18 pump houses in the 2nd phase. The 1st Pumping Station constructed at Malyala, a place located in the upper part of Srisailam Project, has 12 machines, each with a capacity of 5 MWs, making a total capacity of 60 MWs. These machines lift water to a height of 38 meters. Kaleshwaram Project is much bigger than HandriNeeva as its Lakshmi Pump House itself is having 17 machines having a total capacity of 680 MWs.  Gayathri Underground Pumping Station with 7 machines, each having the capacity of 139 MWs is bigger than this Lakshmi Pump House; the total capacity of the Gayatri Pump House is 973 MWs and its distinct feature is its construction at 470 Feet beneath the earth’s surface. In that terms, it is not possible to compare any other pump house with this Gayathri Pump House. 

 Since its commencement almost eight years back, Malyala Pump House of HandriNeeva Project could pump 163.4 TMCs of water in the working span of 1242 days. Another big project Pattiseema could lift 289 TMCs of water during the last 5 years. Taking into consideration  these achievements one could imagine how much water would be made available to the hitherto barren lands of Telangana if the four mega pumps of Link 1 and Link 2 are operated simultaneously.  In this respect, MEIL is creating all sorts of records while executing prestigious Kaleshwaram Project, which is expected to bring a water revolution in Telangana.

MEIL’s Engineering Marvel Converts Telangana’s Dream Into a Reality

Published

on

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 has been named after the goddess Gayatri, successfully completed the wetrun on Sunday night, 11th August. The wet run began with switching on the 5th machine in LUPS. With this, around 3000 cusecs of water risen 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 expected to inaugurate the 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 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 enable us to complete the project in time,” said B. Srinivas Reddy, Director, MEIL
