Thiruvananthapuram’s Pazhavangadi Canal: A Growing Crisis of Waste and Public Health
Residents of Vallakadavu and Sreevaraham in Thiruvananthapuram are facing escalating health risks due to the severely clogged and polluted Pazhavangadi canal. The situation, particularly dire between Kothalam Bridge and Sreevaraham Bridge, highlights a recurring problem of inadequate waste management and its direct impact on public well-being.
The Cycle of Neglect and Disease
The canal is currently choked with slaughter waste and general garbage, creating a breeding ground for disease. Local residents report a surge in contagious illnesses, including dengue and chikungunya, exacerbated by a significant increase in the mosquito population. This year, unlike previous years, no pre-Pongala cleanup efforts were undertaken, leaving the area particularly vulnerable.
Recent heavy rains following the Attukal Pongala festival led to widespread flooding, inundating homes with polluted water and debris from the overflowing canal. Despite the presence of fencing, illegal dumping continues unabated, contributing to the escalating crisis.
Systemic Issues and Lack of Action
The responsibility for cleaning the canal falls on both the city corporation and the major irrigation department. However, according to Vallakadavu ward councillor Shajida Nazar, repeated appeals to these authorities have yielded no tangible results. Garbage originating from the Amayizhanchan canal further compounds the problem, accumulating under bridges and exacerbating flooding.
The Pazhavangadi thodu, a 5.6 km canal, is a critical discharge route for the city, starting near Observatory Hills and draining into Amayizhanchan thodu near Kannanmoola. Its central location through Thampanoor and Pazhavangadi areas makes its condition a matter of significant public concern.
A History of Recurring Problems
This isn’t an isolated incident. Reports from May 2025 detailed similar issues, with the canal overflowing even then, threatening flooding in the Thampanoor area. Past cleanup efforts, while undertaken annually before Pongala, appear to be insufficient to address the underlying problem of consistent waste dumping.
A 12 crore rupee project was approved in January 2025 for the renovation of the Amayizhanchan canal, focusing on retaining wall construction, indicating a recognition of the demand for infrastructure improvements. However, the impact on the Pazhavangadi canal remains to be seen.
The Broader Implications for Urban Waterways
The situation in Thiruvananthapuram reflects a wider challenge faced by many urban areas: the struggle to effectively manage waste and maintain the health of vital waterways. Neglecting these canals not only poses immediate health risks but similarly contributes to long-term environmental degradation and increased vulnerability to flooding.
