The Pamba River, flowing through Kerala’s Western Ghats, gained national attention in August 2025 by being included in the National River Conservation Plan (NRCP). This landmark decision aims to tackle pollution and protect the river’s ecological and cultural legacy.
Geographical Overview: The Lifeline of Kerala’s Heartland
- Origin: Pulachimalai Hill in the Western Ghats, Kerala
- Length: Approximately 176 km, third longest in Kerala
- Course: Flows through the districts of Pathanamthitta, Idukki, and Alappuzha, before joining the Vembanad Lake
- Drainage Basin: Covers a significant part of Kerala’s midlands, supporting agriculture, drinking water, and biodiversity
- Climate & Terrain: Tropical monsoon climate, hilly terrain in origin, with broad floodplains downstream
Why is the Pamba River Geographically and Culturally Important?
- Called the ‘Dakshina Bhageerathi’ or ‘Ganges of the South’ due to its religious significance among Kerala’s millions
- Supports one of India’s largest pilgrimages at Sabarimala Temple, with millions bathing in the river annually for purification

Pollution and Environmental Challenges: What Makes Pamba a Focus Area for NRCP?
- Rampant untreated sewage discharge from towns and villages in the river basin
- Agricultural runoff and solid waste dumping threaten river’s biodiversity
- Riverbank erosion intensifies during monsoon, threatening settlements and farmland
- Elevated levels of bacterial contamination pose health risks to millions who use the river water daily
- Encroachment and illegal construction near riverbanks reduce natural flood buffers
Government & Local Initiatives: Steps Towards Sustainable Conservation
- NRCP funding for wastewater treatment plants across key towns like Chengannur and Ranni
- Riverbank protection with retaining walls to control erosion and flooding
- Efforts to improve water quality monitoring and remove solid waste
- Encouraging eco-friendly pilgrimage practices and compliance with Supreme Court guidelines
Pamba River is both a geographical asset and a cultural treasure for Kerala. Its inclusion in the NRCP provides a critical opportunity for long-term restoration. Protecting this river through scientific management and community participation is vital not only for ecology but also for millions whose lives and faith depend on it.
