Wastewater treatment plant for 1200 p.e. at St-Affrique-les-Montagne, south west of France (Tarn), with 1 vertical flow reed bed combined with a surface flow polishing treatment

Crynant: Two 1,200m2 vertical flow reed beds operated alternately to treat 3,400 m3/d of tertiary municipal waste water.

Large treatment wetland in the northwest of France, near the city of Le Mans,  treating 4000 PE and also large amounts of storm and drainage water. Zero surface water discharge in summer. 

Resolis: Two 200m2 horizontal subsurface flow wetlands operated in paralell treating 10m3/d of secondary sewage.
