A horizontal subsurface flow constructed wetland treating the wastewater from a housing scheme in the tropical island of Mayotte 

This wetland was built for groundwater remediation on the site of a former oil refinery at the State University of New York's Wellsville campus 2008

Two vertical flow wetlands. One is a circulation system treating the pond water. The other treats the wastewater from the outside toilets

"Zero Emission" would be the general goal for sustainability. Especially for industrial production. Tertiary treatment with constructed wetlands may be a proper solution for closing the loop. The new treatment wetland at Changshu Advanced Materials Industrial Park, Haiyu Town, Jiangsu Province, China, is not only reclaiming water. It is a stepping stone for humans searching nature and for endangered species within a widely industrialized zone. Designed as a beautiful park it provides recreational functions and serves as buffer stripe between chemical industries and urban areas.

The wetland visitor center with its terraces on the roof and near the water level reveals a stunning new perspective. Intersted visitors will be given looks inside of the wetland when entering the exhibition on the first floor. Accomplished with a water laboratory and wetland control room the Changshu AMIP wetland center is a perfect place for training and dissemination of environmental solutions.
