Chinaenvironment.com recently reported that the citizenship of Wenzhou (Zhejiang province) is to benefit from the establishment of Asia’s biggest, integrated, fully enclosed and semi-submersible used water treatment system. The announcement was made by provincial officials in a meeting concerning the construction of water-related infrastructure on the 21^st of November.

Wenzhou’s municipal government, in responding to the assessments of the Delegation of Environmental Supervision of the Central Committee, has succeeded in the relocation and technological overhaul of the city’s dated water treatment system, which started in mid-2017. The new site covers 95 acres, which is 192 acres smaller than the previous one, which could be seen as a remarkable increase in the efficiency of land use. Moreover, the complete enclosure and submersibility of the new system could help reduce the harm caused by visual and noise pollution among surrounding neighbourhoods.

The designed capacity of this exemplary piece if infrastructure is 400,000 tons per day, and an upgraded version of the A²/O technique is adopted after an EPC+BOT process of open bidding, which served to prevent the potential loss of procedural utility in design, construction, purchase and operation.
