The Water Resources Department (WRD) will construct a flood protection wall along the Adyar river near Jaffarkhanpet in Chennai at a cost of ₹25 crore as part of disaster management measures, Minister for Rural Development and Water Resources N.

Two bed dams costing ₹31.50 crore will also be built in districts such as Madurai to arrest riverbed erosion and facilitate groundwater recharge.

To improve existing water systems, the WRD will execute 96 works to repair, renovate, and restore waterbodies and irrigation channels across 30 districts, including Tiruchi, at an expenditure of ₹695.42 crore. In addition, 1,628 artificial groundwater recharge structures will be installed across 35 districts at an outlay of ₹28.9 crore.
