Hyderabad: Works on Package 6 of the Kaleshwaram Lift Irrigation Scheme (KLIS) are progressing rapidly with the trial run of the pumping stations likely to be scheduled soon.
Officials of the project as well as the Irrigation Department are gearing up for the release of water from the Sripada Yellampalli project by this month-end to facilitate the trial, a much-awaited mandatory feat to be completed before the lifts are put to operation.
Package 6, which involves an overall cost of Rs 4,961 crore, will provide vital connectivity from KLIS to the Nandi Medaram project, the halfway point to the Mid-Manair project, from where the water flow branches off in the designed directions to irrigate over 37 lakh acres. It includes a new ayacut of over 18 lakh acres, while the rest would be stabilisation part.
The trial will culminate in the wet run of the pumps, which are meant for lifting water from the surge pool. The State government’s approval for this is awaited, a senior official told Telangana Today. The underground pump house complex has come up with seven pumps of 124.5 mw each meant to lift water some 110 m high on a 45-degree gradient to the delivery cistern.
Out of seven pumps installed in the package, four are ready for the wet run and two more will be completed soon. Civil works on Pump No. 7 are expected to be completed soon and will be ready for commissioning by June 15.
The stage is being set for pressure testing and dynamic flow testing in different operating conditions, which will be part of the commissioning process. Twin tunnels that are part of the scheme in Package 6 are also ready. They are designed to carry water from the Yellampalli project to the Nandi Medaram project from where the water will be channeled to the Mid-Manair project. These tunnels are the last link of the main distributary system to support the
Hyderabad Metropolitan Water Supply System also, besides extending irrigation to seven districts in north Telangana.
The Yellamapalli project has a gross storage of 8.56 tmc as on April 14. Water available in the project can be released through the tunnels to meet any emergency situation in the command area once the flow test requirements are complied with.
