HYDERABAD: The state government has entrusted the responsibility of vetting the detailed project reports (DPRs) prepared by the irrigation department to Water and Power Consultancy Services (WAPCOS), a central public sector undertaking. Orders to this effect were issued here on Thursday.
The irrigation department prepared DPRs for constructing various reservoirs have a storage capacity of 21 tmcft to 50 tmcft at Mid-Manair, Tadakapally, Gandhamalla, Baswapur, Pamulaparthy and Nizamsagar as part of the Pranahita-Chevella project.
“As the department prepared the DPRs, we have felt that it should be vetted by a third party agency so that there will be no mistake in executing the project,” an official said.
The government also wanted WAPCOS to submit the topographic survey of the water conductor system from Mid Manair, Tadakapally, Gandhamalla, Baswapur, Pamulaparthy, Nizamsagar and balancing reservoirs.
The study of water conductor system means whether the capacity of the proposed canals, tunnels and pipelines at these places are estimated properly by the department or not. If the capacity is insufficient, then WAPCOS will suggest corrections, sources said.
The third task entrusted to WAPCOS is to study the submergence area at the proposed Tummadihatti Barrage with 152-metre FRL (full reservoir level) in Adilabad district using LIDAR survey. The Maharashtra government objected to the Telangana government’s proposal to construct a barrage at Tummadihatti at at a height of 152 metres citing likely submergence of a huge area in Maharashtra. Now, the government is also taking up a LIDAR survey to check whether Maharashtra’s argument is technically correct or not.For all the three works, the government sanctioned an additional amount of Rs 2.85 crore to WAPCOS.
The government has already ordered for a LIDAR survey of around 700 sq km from Medigadda to Yellampalli. Today it wanted a survey on the likely areas of submergence under the Tummadihatti barrage (300 sq km). In all, the survey will be carried out in the state for about 3,400 sq km.
