The Kaleshwaram Lift Irrigation Project has the
potential to create an engineering marvel and show the path for the country in
coming up with innovative approaches to solve water woes, but it has its own
set of dangers, says Srinath Rangarajan
The results of the recently held Assembly Elections in
five states have hogged the limelight for many reasons. While the resurgence of
Congress in Madhya Pradesh, Rajasthan, and Chhattisgarh was the silver lining
for that party, the state of Telangana told a completely different story. The
incumbent political party, the Telangana Rashtra Samiti (TRS) won in a
resounding manner defeating Prajakutami, a united opposition front. The
emphatic victory of TRS has made many analysts and thinkers across the country
ponder over the reasons for the impressive electoral performance. Over the past
four and a half years, TRS launched many social welfare schemes, irrigation
projects and financial assistance programs. Out of all these, the Kaleshwaram
Lift Irrigation Project (KLIP) is something unique in many aspects. It is being
built at a cost of more than Rs 80,000 crore and is the costliest irrigation
project undertaken by any state in India so far.
KLIP was originally conceived from the Dr BR Ambedkar
Pranahita Chevella Sujala Sravanthi project. This was originally supposed to
utilise 160 thousand million cubic feet (TMC) of allocated waters of the
Godavari river. Hence, a barrage was proposed at a place called Tummidihatti
near the Maharashtra border to divert 160 TMC of water and use it for
irrigation
However, irrigation projects across rivers have at
various stages, issues associated with them starting from the pre-construction
stage to the post-commissioning phase. The Pranahita Chevella project is being
built across river Godavari and this river originates in Maharashtra and has a
catchment basin spreading across the states of Telangana, Chhattisgarh, Odisha
and Andhra Pradesh. Therefore, it is anything but unnatural for this project to
fall victim to the unceasing interstate water disputes between the states
having stakes.
The Maharashtra Government repeatedly expressed
concerns over fixing of the Full Reservoir Level (FRL) for constructing the
Tummidihatti Barrage due to submergence of 3,786 acres of land in their
territory. A considerable portion of this land constitutes the environmentally
sensitive forest areas. Consequently, the FRL had to be reduced from +152.00 to
+148.00 to reduce the submergence from 3,786 to 285 acres. This was mutually
agreed upon by both the State Governments and a final agreement was reached
upon to construct a barrage at Tummidihatti with FRL of +148.00 on August 23,
2016.
However, this is where the actual problems came to the
surface. Detailed water availability studies carried out by the Government of
Telangana and subsequently by the Central Water Commission (CWC), New Delhi
found out that divertible flows at an FRL of +148.00 after deducting the
upstream abstractions by Maharashtra would only be 44 TMC against the
originally planned 160 TMC. Thus, CWC has advised the Government of Telangana
to look again into the location of the barrages to match the demand and supply
of water. This made the Telangana Government dependent on the area in the
downstream side on the river Pranahita, the largest tributary of river
Godavari.
It is in this context that an alternate location for
constructing the barrage across Godavari was investigated by M/S WAPCOS Ltd by
using the latest Light Detection and Ranging (LiDAR) technique of surveying and
the location was proposed at Medigadda near Kaleshwaram in the
Jayashankar-Bhupalapally District of Telangana. The water availability by CWC
at this location has been assessed as 284.3 TMC which comfortably meets the
supply and demand. The original project of Pranahita Chevella has now been
divided into two components namely BR Ambedkar Pranahita Project by
constructing a barrage at Tummidihetti to facilitate irrigation and water
supply to Adilabad District in Northern Telangana and the remaining segment is
the KLIP.
Geographically, Telangana is situated on the Deccan
Plateau at a higher elevation than the elevation at which the river Godavari
flows in the state. Hence, irrigation through gravity canals alone is not a
feasible option and lift irrigation should be employed. In the case of KLIP,
the lift heights have become as high as 350 meters due to the need for
redesigning the project because of the changed location at Medigadda. This
change in location has also imposed the need to reverse the flow of the mighty
Godavari across the Medigadda Barrage. The project now constitutes seven links
and 28 packages, thus aiming to create a new ayacut of 18.25 lakh acres in 13
districts and stabilisation of existing ayacuts of 18.82 lakh acres. The
project boasts of 1,531km long gravity pressure canals, 203km long tunnels,
98km long pressure pipelines, 1,832km long water supply routes, 22 lifts, 22
pumps, 14 reservoirs and 19 electrical power substations. The project has been
racing against time with record concrete pours per day. KLIP witnessed
reinforced cement concrete pour of 22,584 cum from December 22 to 25, 2018 on
the spillway piers in Medigadda Barrage breaking all previous world records in
concrete pour.
There are many other firsts and records in this
project. The surge pools in ‘package six’, which are used to store water from
tunnels and lift them upwards, are the largest in the world. The pumps
installed in ‘package eight’ which have successfully completed the dry run,
popularly called as the “Bahubali Motors”, have a capacity of 89.14 cumecs per
second and require a whopping 139 MW power for operation, both of them being
world records. Similarly, package 10 boasts of Asia’s biggest open surge pool.
There are also state of the art gas grid substations which occupy very less
space underground, compared to conventional substations. The civil works being
completed also cater to the possible future expansion. Various allied and
associated works like compensatory afforestation are also proceeding at a
breakneck speed. All this has led to the actual cost of the project as worked
out to be Rs 80,190 crore.
The KLIP is being seen as a solution to end the water
woes of Telangana by providing uninterrupted water supply to agriculture for
all the three seasons of the crop and providing drinking water to several
villages, towns and cities of the state -planned under another flagship project of Telangana
“Mission Bhagiratha”.
The other takeaways include the timely and pragmatic
resolution of interstate water disputes between Maharashtra and Telangana.
Despite constitutional and statutory mechanisms, setting up of various river
water boards and tribunals, many states across the country have not been
successful in resolving contentious issues on the river water sharing for decades.
Telangana and Maharashtra have shown the maturity and leadership to move
forward in a rational way without harming the interests of each other. They
showed the way forward for the country in this regard. Similarly, the CWC and
Ministry of Water Resources have also been highly supportive in timely
assessments and clearances. KLIP has received 10 statutory clearances from CWC
within a period of nine months including cost appraisal, environmental and
forest clearance — an unusual speed for administrative approvals. Despite TRS
and BJP being at the opposite ends of the political spectrum, the proactive
nature of CWC to the State Government displays a perfect example of cooperative
federalism. The CWC has also appreciated the various technical aspects and the
speed of execution of KLIP.
While everything seems to be going well, there are
matters to be taken care of. The completion of works within the schedule
timeline of June 2022 without any cost escalation remains a challenge.
Technical issues may crop up during operations even if one loose end is left
unaddressed. Apart from these, the Telangana Joint Action Committee (TJAC), an
activist group in the State, is claiming that the project does not necessitate
a change in location from Tummidihatti to Medigadda, notwithstanding the CWC’s
recommendations. They argue that enough water can be drawn through gravity
canals from Tumidihetti. They even claim to have done a scientific analysis on
water availability at Tummidihatti.
Apart from this, they are also contesting the other
stated benefits of KLIP with respect to crop production, farmer welfare etc.
While it is true that officials from Government and TRS spokespersons have been
negating these claims of TJAC in Television debates, it is in the best
interests of transparency and accountability, the Government of Telangana
should come out with more technical and authentic clarification in this regard.
And it is also true that some of the stated benefits can only be noticed once
the whole project becomes operational. But the biggest issue is the operation
and maintenance cost that would be needed to keep a project of this magnitude
running. Some estimates by civil society activists peg it to be around Rs
15,000-20,000 crore per annum.
There are also fears that KLIP being a State
Government project with enormous financial burden, can impair the State’s
economy — with regards to its execution as well as subsequent annual
maintenance costs. Probably it is for this reason, the Telangana Government is
repeatedly seeking the status of National Project for KLIP. Time will only
answer whether all these fears are indeed true or not.
KLIP, in due course of time has the potential to
create an engineering marvel and show the path for the country to move ahead in
coming up with bold and innovative approaches to solve water woes. This does
not mean to say that there are no dangers lurking around. But the way in which
the TRS Government headed by Chief Minister K Chandrashekar Rao and Irrigation
Minister T Harish Rao have handled the
situation instills more hope than fear.
