Advancing Stormwater Drain Infrastructure in Chennai

The Greater Chennai Corporation (GCC) is set to advance its integrated stormwater drain (ISWD) project with the floating of tenders for the third component (M3) in Perungudi and Sholinganallur areas on February 16. Covering a total length of 360 km, the project, estimated at ₹1,714 crore, will be executed alongside the Pallikaranai marshland and the south coast watershed area.

Despite setbacks including resident agitation and legal challenges, the project has obtained crucial Coastal Regulation Zone (CRZ) clearance from the Ministry of Environment, Forest and Climate Change. Tenders have been issued for nine different packages covering various localities, aiming to streamline the drainage system and mitigate flooding risks.

The project, funded in part by the German bank KfW, has witnessed modifications in contractor qualifications and package sizes to expedite completion. With 77% of Phase I works and 46% of Phase II completed, the GCC is gearing up for the final phase, aiming for comprehensive stormwater management across key areas of Chennai.
