Citizen Groups Urge Basin-Wide Plan To Save Chennai Wetlands
Citizen groups say Chennai’s Pallikaranai watershed should be managed as one connected water system.
It includes many lakes, ponds, canals and wetlands.
Water from these areas eventually drains toward the Pallikaranai marshland.
The groups say building projects and encroachments have damaged parts of this system.
They want government departments to work together instead of handling each lake separately.
They also want wetlands and floodplains to be clearly marked and protected.
Sewage, garbage and construction debris should be kept out of the waterways.
The groups say better drainage and lake restoration could help reduce flooding and water stress.
They have proposed a charter listing problems and actions for government agencies and communities.
The Chennai Wetlands Action Collective and Oorvani Foundation released a Citizen’s Charter for the Pallikaranai watershed.
The watershed includes 65 major lakes and hundreds of ponds draining toward the protected Pallikaranai Ramsar wetland.
Citizen groups want an independent inter-departmental committee to coordinate planning, assign responsibilities and set implementation timelines.
The charter calls for wetland and floodplain protection, action against encroachments, sewage and dumping, and improved drainage infrastructure.
Groups also seek scientific lake restoration, canal clearance, an end to further Perungudi dumping and dedicated flood-mitigation plans for vulnerable areas.

“Navalur lake has been restored, but its downstream outlet does not have the capacity it needs. The canal is clogged with vegetation, sewage and waste, while walls and construction have further obstructed the natural waterway. Gandhinagar floods every monsoon because there is no proper storm drainage”

“The charter is a collective reference to the key challenges facing the watershed, while providing a common platform to advocate for its protection and sustainable management”
