The Pamba river originates from the Western Ghat and flows westerly and discharges

The survey has been conducted by Central Pollution Control Board in collaboration with Kerala State Pollution Control Board. The survey revealed that the solid wastes and sewage generated at Pamba city during festival season causes severe pollution of Pamba river.  Lack of sanitary latrines, lack of facilities for sewage collection and treatment and the accumulation of wastes discharged  from hotels and commercial establishment located at Sabarimala are the major sources of the pollution of Pamba river.  It is recommended that construction  of a series of check dams upstream on the two branches of the river has to be undertaken so that sufficient water can be stored and released during the summer months, especially  during the Sabarimala festival and provide  more sanitary and water supply facilities to the pilgrims during festival season.
