Green-bridge construction for flow control and effective treatment of sewage.
and three to four hydro-cell Green –Bridge acts as a reservoir of microbes Microbial storage at the green bridges and mingling by bottom of the hydro-cells.
Microbes feed on the pollutants and treat the water Aquatic plants grown on Green-bridges & along drain-bank absorb nutrients to treat waste water.
Green Bridges for Buddha Nala Restoration
