Floating Treatment Wetlands (FTWs) have emerged as an innovative and sustainable solution to address water quality issues and enhance environmental health. The establishment of FTWs at the middle canal of the Colombo Regional Center at the Open University of Sri Lanka, courtesy of the Sri Lanka Land Development Corporation’s generous donation, represents a significant step toward improving water quality and promoting ecological balance.

These FTWs consist of compact artificial platforms designed to facilitate the growth of aquatic emergent plants directly on the water surface. The roots of these plants extend both horizontally through the floating structures and vertically into the water, forming dense columns of roots with a substantial surface area. This unique configuration enables them to efficiently absorb nutrients and pollutants from the surrounding water, contributing to water quality improvement.
