Context

 As part of the creation of the High Speed Train Station of Reims, Reims Métropole issued a call for a project to store and to treat the storm water of this non-residential area. The original project was a concrete tank buried under soil.

 

Targets

 Sinbio’s target was to design an alternative project to minimize the use of concrete and give an added value for landscape, habitat and recreational uses. The proposal was to create three different areas:  a pond, a reed bed filter, and a surface flow wetland. Construction began in 2009 with commissioning in 2011.
