The Floating Treatment Wetland (FTW) was inaugurated on World Wetlands Day (February 2) in Neknampur Lake in Hyderabad to clean and purify the polluted waterbody.
Plants planted on FTW can clean the lake by absorbing nitrates and Oxygen pollutants in the water.
The FTW is a joint effort Hyderabad Metropolitan Development Authority, the Ranga Reddy district administration.
It has already been recognised by the India Book of Records as the largest FTW in the country.
Based on the soil-less hydroponics technique, the FTW has been made in this lake.
Cleaning agents planted on FTW include vetivers, citronella, hibiscus, flowering herbs, tulsi and ashvagandha.
