IWA Global Project Innovation Award: Green Campus Nourished by Reclaimed Water – Decentralized System of Zero Discharge and Maximized Water Reuse


The project is featured by a novel integration of conventional biological treatment, membrane filtration, and water quality polishing through a natural purification process in the environmental lakes. Dual-quality water reclamation is also practiced for supplying high quality and normal quality reclaimed water to meet the needs of different reuse purposes. With a maximum capacity of 3000 m3/d of fresh water supply from groundwater wells, the total water demand of more than 6000 m3/d has been sustained. Zero discharge of wastewater is realized and water becomes ‘alive’ in the local water metabolic system which provides a sound water environment and beautiful living condition in the university campus.
