Jaipur, April 24 -- In a major push to strengthen water infrastructure, the Rajasthan government has kicked off a Rs.225 crore modernisation drive for three key dams in the Chambal basin, aiming to boost irrigation efficiency, secure drinking water supplies, and enhance hydropower generation without halting operations. Water resources minister Suresh Singh Rawat said the state has launched a large-scale modernisation and rehabilitation drive for Rana Pratap Sagar Dam, Jawahar Sagar Dam, and Kota Barrage along the Chambal River system. The works fall under the Dam Rehabilitation and Improvement Project (DRIP Phase-II), with tenders already issued. The drive targets dam safety enhancements, upgrades to outdated mechanical systems, and better water management in the region. Officials say it will ensure efficient irrigation, stable drinking water, and increased power capacity. Constructed in 1960, the Kota Barrage has not seen significant hydro-mechanical work since its inception. Of its 19 radial gates and two sluice gates, several radial gates are deteriorated, and the sluice gates have remained non-functional for over three decades. The project will replace all 19 radial gates, two sluice gates, stop-log gates, gantry cranes, and electrical systems. Authorities will maintain water levels at 854.50 feet during upgrades to avoid disrupting irrigation and drinking water in Kota and Bundi districts. All work will proceed under full reservoir conditions. Located in Chittorgarh district, Rana Pratap Sagar Dam serves as a major reservoir under the Chambal project, with 172 MW hydropower capacity. Given its national importance, the government has prioritised its maintenance and upgrade. Modernisation includes replacing 17 vertical crest gates, gantry cranes, four sluice gates, and stop-log gates, plus repairing the ski-jump bucket. These works will occur without interrupting power generation or water supply. The dam holds a flood discharge capacity of 18,408 cumecs. Situated downstream of Rana Pratap Sagar in Bundi district, the Jawahar Sagar Dam-built in 1972-will receive structural and technical upgrades. Efforts will strengthen its foundation and boost efficiency at its 99 MW powerhouse. The dam, vital for regulating downstream flow, features 12 radial gates and 67.11 MCM storage capacity. Modernisation will improve flood control and water management. The minister said all works will adhere to quality standards and timelines. Upgrading these dams should extend their lifespan and optimise water resource use. "The project will particularly benefit the Hadoti region by ensuring long-term irrigation support, reliable drinking water supply, and sustained urban development. The initiative would strengthen water security and provide a long-term boost to the region's agricultural and economic growth," said Rawat....
