Sewage lines in all Wards in City

The existing sewerage system in the city (laid in 1945) covers 43 out of 100 wards, with a central Sewage treatment plant at Muttathara which has a capacity of 107 MLD. The length of the pipeline network is 600 km with around 52,000 connections.

Works for sewerage network under Atal Mission for Rejuvenation and Urban Transformation (AMRUT) and Jawaharlal Nehru National Urban Renewal Mission (JNURM) projects are being carried out. Designs are to be prepared for the remaining 22 wards.

KWA has appointed Rudrabhishek Enterprises (REPL), Delhi-based infrastructure consultants, to prepare DPR for the reintegration of existing sewerage systems, and to provide a sewage management system for areas not covered in Thiruvananthapuram Corporation.

The centralized sewage system is now outdated, and the city requires decentralized sewage treatment plants. Since adequate funds are available, this may be looked into. The preparation of DPR is a crucial step that needs to be supported.
