Central Experts Review 1,700-Crore Kochi Sewage Redesign to Resuscitate Polluted Canals
A high-level inspection team has evaluated proposed sewage treatment locations and pipeline networks to address Kochi's severe waterway contamination. The project awaits final funding to execute a massive infrastructure overhaul aimed at making city canals navigable and sanitary again.
Federal Team Evaluates Sanitation Infrastructure Needs
A five-member central government expert delegation recently completed an on-site inspection of Kochi’s proposed sewage treatment plants (STPs) and underground drainage networks. This visit serves as a significant step for the Integrated Urban Regeneration and Water Transport System (IURWTS), a project designed to halt the ecological decay of the city's water bodies. Sources within the Kerala Water Authority (KWA) indicates that the team found the local canals in a state of advanced degradation, characterized by stagnant, blackish water and severe odors.
Legislative and Financial Framework
The project managed by Kochi Metro Rail Limited recently saw its budget estimates climb from ₹1,386 crore to ₹1,700 crore, necessitating a resubmission for administrative approval last May. Financial responsibility is split between the Central government and the state via the Kerala Infrastructure Investment Fund Board (KIIFB). Despite ongoing restructuring at KIIFB, officials confirm the sanitation initiative remains a high-priority item due to its immediate impact on public health. The scope of the project extends beyond Kochi Corporation limits to include:
- Kalamassery Municipality
- Thripunithura Municipality
- Thrikkakara Municipality
Strategic Site Selection and Capacity
The overhaul centers on two primary processing hubs designed to manage the heavy outflow from households and businesses. A major 55 million litres per day (MLD) capacity plant is slated for a 13-acre KWA plot in Elamkulam. A secondary facility at Muttar will provide an additional 50 MLD of treatment capacity. Experts noted that current septic tank overflows in areas like Panampilly Nagar frequently drain into canals, while tidal shifts force this contaminated water back into residential properties. Professionals involved argue that establishing a comprehensive underground pipeline is the only viable method to permit the subsequent cleaning and navigation of Kochi's historic canal system.
