Urban ponds are prone to eutrophication problems that act as a source of water for irrigation, household chores like washing, bathing, recreational activities, and aquatic ecosystems. The floating Treatment Wetland System (FTWS) is an innovative and cost-effective phytoremediation technique to improve the water quality of freshwater resources. This project aims to remediate the polluted water of Nagdaha through the use of rafts and hanging a root network. The hanging root network provides an opportunity for biofilm growth. The root and biofilm combinely absorbs nutrients from the water and helps to remediate the polluted water bodies. It is an eco-friendly, cost-effective means to improve water quality by employing the purification processes associated with natural wetlands. The microcosm setup has been constructed on the premises of the Kathmandu Valley Water Supply Management Board (KVWSMB).
