Preparations Underway for Adyar River Mouth Dredging

Ahead of the planned dredging at the mouth of Adyar river, the Water Resources Department (WRD) conducts a comprehensive bathymetric survey to assess silt accumulation. This survey, conducted both on the river and seaside near the estuary, aims to map underwater features and determine the extent of sediment deposits.

With nearly ₹12 crore allocated for the project, scheduled for May or June after the sea turtle nesting season, approximately two lakh cubic metres of sediment are expected to be cleared. The State government’s prioritization of this initiative follows concerns raised by residents about flooding in December 2023. Additionally, the sand cleared from the river mouth will be utilized for beach nourishment to mitigate erosion, further enhancing floodwater drainage capacity up to 60,000 cubic feet per second.
