Once the work is accomplished, the reservoir would have 105 mcft of further capability, officers stated
Preliminary work for the restoration of Veedur dam close to Vikravandi in Villupuram district has begun, with the Water Resources Organisation of the Public Works Department (PWD) finishing up aerial survey with the assistance of drones to map the dam’s profile and its water capability.
“The previous survey conducted by the Institute of Hydraulics and Hydrology, Poondi in September had identified silt accumulation up to 105 million cubic feet (mcft),” a senior PWD official stated. The second survey with drones would map the gradient, dam profile, contour stage, accumulation of silt and the storage capability of the dam.
“The administration has constituted a survey team for all the five villages located near the dam. The drones are expected to complete the aerial survey mapping of the parameters within a week’s time,” the official stated.
The authorities has sanctioned a sum of ₹43 crore for restoration of the dam.
The Veedur dam, commissioned in 1959, is now a significant supply of irrigation for villages in Villupuram district and the neighbouring Union Territory of Puducherry.
The canal system of the reservoir includes 17.6 km, of which 16.three km passes via Tamil Nadu and 1.three km via Puducherry. The dam is positioned on the confluence level of the Varaha and Thondi Rivers and irrigates about 2,200 acres in Villupuram district and 1,000 acres in Puducherry.
According to an official, the dam’s storage capability is 605 mcft. The desilting train would improve the dam’s storage capability and about 105 mcft of silt could be eliminated.
The venture additionally contains enchancment work. The eliminated silt could be deposited within the foreshore bunds to a distance of 6 km to stop encroachments and flooding on the opposite aspect, the official added.
The PWD may also be finishing up long-pending enchancment work akin to restore of shutters, strengthening of bunds and repairing department channels.
The desilting work could take about one-and-a-half years. Once the work is accomplished, the reservoir would have 105 mcft of further capability.
