Trash Barrier Installed In Bagmati River To Collect Floating Waste, Expansion Planned At Five More Locations

Kathmandu: The Bagmati Civilization Integrated Development Committee under the Ministry of Urban Development has installed trash barriers to collect floating waste in rivers in Kathmandu. The installation has been completed at Guhyeshwori. The system will be gradually expanded to five more locations along the Bagmati River.

According to the ministry, work is underway to install trash barriers at a total of six locations. These include Guhyeshwori, Gokarna Barrage, Tilganga Eye Hospital, the Bagmati–Manahara Interchange, UN Park, and the Karmanasa Interchange of the Manohara River. A contract agreement worth Rs 6.5 million has been signed for the project.

Trash barriers are designed to stop floating waste such as plastic, polythene, bottles, and pieces of wood and collect them at a fixed point. Due to rapid urbanization and unorganized waste management, large amounts of floating waste flow through rivers such as the Bagmati, Bishnumati, Manohara, and Dhobi Khola in the Kathmandu Valley. The installation of trash barriers allows waste to be removed without obstructing the natural flow of the river. This helps reduce river pollution.

The waste collected through the trash barriers can be regularly removed, segregated, reused, and safely managed. Officials say this will help reduce pollution and contribute positively to river aesthetics, the protection of aquatic life, and public health. The system includes a structure with a rubber conveyor belt and floating components. It prevents plastic, polythene, bottles, pieces of wood, and other floating waste from moving downstream. The barrier automatically rises and falls with changes in the river’s water level, without disrupting water flow.
