Tiruchirappalli — an industrial and educational hub on the banks of the Cauvery River — has an extensive network of Cauvery irrigation canals, stormwater drains, and TWAD sewer infrastructure. Silt accumulation from Cauvery flows and industrial runoff from Ariyamangalam SIPCOT and Golden Rock creates persistent drain blockages that exacerbate flooding in Woraiyur, Ariyamangalam, and K.K. Nagar.
VARMAN operates across all 4 TCC zones and 60 wards — deploying jetting trucks, hydraulic excavators, and suction tankers for Trichy's Cauvery canal network, urban stormwater drains, and TWAD underground sewer mains.
