The government of India has launched the world’s
largest underground water pumping station in Telangana – the Laximpur
underground pumping station. The project, which was constructed by Megha Engineering and Infrastructures
Ltd, has successfully commenced operations.
The underground water project which began with
switching on the fifth machine in LUPS, will enable pumping up of 3,000 cusecs
of water to a height of 111m to be evacuated into the Mid-Manair through the
gravity canal.
According to Megha Engineering and Infrastructures
Limited (MEIL) director, B Srinvas Reddy, the pump house was named after
goddess Gayatri and has successfully completed the water run. “This is an
extraordinary underground water pump, 470 feet below the ground with twin
tunnel to ensure uninterrupted pumping and three largest surge pools have been
built to store enough water,” he said.
“This is an ultra mega project having 7 motors each
with a capacity of 139MW. The motors can lift 3 TMC of waters per day. This is
a true example of ‘make it in India’ as these giant motors were developed in
the country with computational fluid dynamics (CFD) technology,” he added.
The project has pumping capacity of 2 TMC of water
per day. Massive underground caverns have been excavated to construct the pump
house and surge pools to lift incoming water from underground. The caverns are
140 m deep, 25 m wide and 65 m high.
Its Service Bay is located at 221 m below ground,
while the pump bay is at 190.5 m and transformer bays are at 215 m with its
control room at 209 m underground. The pump house forms part of the mega
project on river Godavari aimed at transforming Telangana from a drought-prone
to a drought-proof State.
The project will help transform the parched dry tracts of Telangana and enable live storage of water in reservoirs throughout the year in the Godavari River Belt. The pump house will also enable reverse pumping of Godavari water, thereby rejuvenating the hitherto dry areas en route.https://constructionreviewonline.com/2019/08/india-inaugurates-worlds-largest-underground-water-pumping-station/
