Hyderabad: The crucial Nandimedaram pumphouse, part of the mega Kaleshwaram Lift Irrigation Scheme, on Wednesday notched two more milestones with successful wet runs – pumping of water – using its pump numbers three and four. With Wednesday’s wet runs, so far, the irrigation department engineers have successfully test-run four of the seven pumps at the pumphouse.
The first two pumps at Nandimedaram, officially named ‘Package 6’ of the Kaleshwaram project and built at a cost of Rs 4,961 crore, were successfully tested on April 24 and April 25, respectively.
On Wednesday, the wet run of the third pump was successfully completed early in the afternoon followed by the running of the fourth pump later in the evening. The 124.4 Mega Watt capacity pumps lift water vertically to a height of 110 metres with each pump and pour the water into a cistern from where it flows via gravity to the Nandimedaram reservoir. When all seven pumps are operational, between them, they can lift 634 cusecs of water.
Wednesday’s test runs of pumps three and four were overseen by Officer on Special Duty (Irrigation) at the Chief Minister’s office Sridhar Rao Deshpande, irrigation department engineer in chief Venkateswarulu, advisor to the Chief Minister (lift irrigation) Penta Reddy. Speaking after the wet run on Wednesday, Deshpande said they were confident of a glitch-free test run after the successful running of the first two pumps earlier in April.
He said the progress being achieved in the project is a result of Chief Minister K Chandrashekhar Rao’s vision, determination and willpower that has made the Kaleshwaram project possible. He said the day was not far off when water from Kaleshwaram project will irrigate large swathes of farmland in the State, providing farmers in Telangana a chance to boost crop production through careful use of water.
Water for the test run of the pumps, in April and on Wednesday, was released from the upstream Sripada Yellampalli reservoir to the surge pool of Nandimedaram pumphouse. After water from the pumphouse reaches the Nandimedaram reservoir it will flow to the Laxmipur surge pool (Package 8) of the Kaleshwaram project. From here, water will be lifted to a height of 140 metres and let out to reach Mid-Manair reservoir from where it will be let out into the Sri Ram Sagar Project canal before finally being distributed through smaller canals and channels to agriculture fields.
