Patni Kaushik was in deep slumber at his house in Ahmedabad within the early hours of Monday when his cellphone started ringing round 2am. The order from his superior was sufficient to wipe the sleep away.
“I used to be tasked with dewatering a 10km stretch of the Machchu river,” mentioned Kaushik, deputy engineer with Gujarat Water Assets Improvement Company Restricted (GWRDCL).
Lower than eight hours later, Kaushik and 20 colleagues arrange two massive pumps at one fringe of the river to start draining it. Over 48 hours later, the 2 pumps deployed by his group drained out not less than 700,000 litres of water from the river to cut back its water stage.
Their large effort, mixed with an identical however smaller train by the Rajkot irrigation division, could find yourself proving essential within the restoration of not less than two our bodies nonetheless suspected to be lacking following the collapse of the cable bridge over this river on Sunday night.

The water-draining train is harking back to an identical effort throughout the Thailand cave rescue in 2018, when tons of of thousand of litres had been faraway from the cave and
A surrounding hills each hour in a profitable try to avoid wasting the 12 trapped kids and their soccer coach. That operation was recreated in a current movie, 13 Lives, and a mini-series, Thai Cave Rescue. There, the mission was to avoid wasting lives; right here it’s to get well our bodies.
For 300-odd employees from half-a-dozen companies working for the third day to search out the lacking our bodies, what Kaushik’s group manages to realize could also be essential. “If the pumps can cut back the water stage by even a pair extra toes, we might be able to discover the our bodies,” mentioned Prasanna Kumar, the Nationwide Catastrophe Reduction Drive (NDRF) commandant overseeing the search operations.
The final of the our bodies was recovered on Monday. Since then, the search efforts haven’t yielded any fruit. They’ve pressed 40 boats into service in a 200m x 100m space of focus within the river, and used a specialised machine to take away the hyacinth weeds from the soiled water, however to no avail.
In a single nook of the river, about 200m from the principle search space, Kaushik’s group is on the job with pumps. “We now have deployed two pumps of fifty horsepower every. They’re pumping out round 12,000 litres of water each minute,” he mentioned.
Aiding them are 4 smaller pumps — every with 6.5 horsepower capability — pumping out 1,200 litres each minute.
As a result of a shut dam 10km away, the stretch of the river the place the accident occurred incorporates stagnant water, and a number of it comes by way of sewers from Morbi city. The water 15 toes deep at some factors, and this — together with poor visibility resulting from grime –has hampered the search.
On Monday morning, the primary motion to cut back the extent of water within the river was to set off a blast at a 3m tall examine dam to launch the water and cut back the extent across the search space. Since that was not sufficient, pumps had been pressed into service. The water pumped out from the affected area of the river is being pumped out into the opposite facet of the examine dam.
For the lads pumping out the water, there are challenges galore. “We might have most popular a flat floor, however right here the pipes carrying the water are positioned up a slope. That’s slowing the discharge pace of water,” mentioned Naveen Chavda, GWRDCL’s pump in-charge.

Barring a 30-minute break for the pumps on Tuesday night time, the dewatering course of has been happening round the clock.
These pumps are usually used to empty out water from flood-hit areas each monsoon. “This can be a struggle towards time. The earlier we are able to drain out the water, the faster the our bodies may be discovered,” mentioned Jatin Delvadiya, deputy engineer with the Rajkot irrigation division.
The first companies concerned within the search, in the meantime, mentioned that whereas they had been trying to find two confirmed instances of individuals lacking within the water, they might not be stunned if extra our bodies had been discovered when the water stage dipped sufficient.
“For now, two individuals are reported lacking. However typically what occurs in such tragedies are that there are some victims whose disappearance isn’t reported,” mentioned AK Bishnoi, director of the Gujarat State Hearth Companies.
