Tamil Nadu Minister Nirmalkumar says Vaigai dam silt removal will be phased

Tamil Nadu Minister for Law and Energy C. T. R. Nirmalkumar says silt from Vaigai dam will be lifted in phases due to the long-drawn process. The dam's maximum storage level is 71 feet, with approximately 15 feet filled with silt. The government has approved the project, but it will take nine years to complete, with farmers' interests being prioritized. The operation should begin when water levels are low to avoid further delays.

Tamil Nadu’s Minister for Law and Energy, C. T. R. Nirmalkumar, has outlined a phased approach to desilt the Vaigai Dam, a project that has remained unaddressed for over 70 years. The dam, which has a maximum storage level of 71 feet, currently has approximately 15 feet of its capacity occupied by silt, significantly reducing its operational efficiency. The government has formally approved the initiative, but span nine years due to the complexity and scale of the operation.

The phased desilting strategy aims to minimize disruptions to water supply and agricultural activities, with farmers’ interests prioritized throughout the project. Desilting will be carried out during periods of low water levels to optimize efficiency and reduce the risk of delays. This approach aligns with broader challenges in dam desilting, which often involve technical, environmental, and logistical hurdles.

Experts emphasize the importance of thorough sediment assessment, appropriate equipment selection, and environmental safeguards to ensure the project’s success. The Vaigai Dam initiative reflects a growing recognition of the need for sustainable water infrastructure management, particularly in regions where siltation threatens irrigation, hydropower, and flood control capabilities.
