Concerns are growing in Thiruvananthapuram over possible flooding linked to changes in the natural drainage network feeding the Akkulam-Veli backwaters. Experts have warned that channels meant to carry excess water are being narrowed or covered, raising fears that heavy rain could lead to waterlogging and overflow in nearby areas.

The warning focuses on natural drains that play an important role in moving stormwater toward the backwaters. When those routes are obstructed or reduced in size, runoff can slow down or collect in built-up parts of the city, increasing the risk during intense rain.

The EPRC has called for a stop to what it describes as unscientific works affecting these drainage paths. The group’s concern suggests that construction or alteration without proper hydrological planning could worsen flooding instead of improving local infrastructure.

The issue highlights a wider urban challenge: balancing development with the protection of natural water channels. In a low-lying and water-sensitive area such as the Akkulam-Veli region, experts say keeping drains open and functional is critical to reducing flood risk.
