Once the work is accomplished, the reservoir would have 105 mcft of extra capability, officers mentioned
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 mentioned. The second survey with drones would map the gradient, dam profile, contour degree, 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 mentioned.
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 contains 17.6 km, of which 16.3 km passes via Tamil Nadu and 1.3 km via Puducherry. The dam is situated 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 can be eliminated.
The challenge additionally contains enchancment work. The eliminated silt can be deposited within the foreshore bunds to a distance of 6 km to stop encroachments and flooding on the opposite facet, the official added.
The PWD can even be finishing up long-pending enchancment work reminiscent of 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 extra capability.
