The Shanghai Jiading Nanxiang Sewage Disposal Plant PPP Project concerns the development of an underground wastewater treatment plant underneath an urban park.
The plant will use the advanced anaerobic-anoxic-oxic (AAO) treatment technology to purify water and meet discharge standards.
When completed, the plant will be able to treat 50,000 cubic metres of sewage a day in the first phase and 150,000 cubic metres a day when fully built.
It is among the first batch of PPP projects in Shanghai after the initiation of the public-private partnership model (PPP) and enactment of new PPP regulations.
