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. 

 

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

Castelluccio is one of the best hotspot of Central Italy, with its spellbound village and the great plateaus at 1400 m a.s.l. in the Sibillini mountain park. The new Constructed Wetland will treat the wastewater of Castelluccio village and tourism facilities, that progressively shift from less than 50 persons during winter up to 1000 or more persons during summer. The current treatment plant is inadequate to support this great variation. The new multistage CW system is constituted by a French scheme system of 1800 m2 followed by two parallel free water-pond system as polishing stage and recreational amenity (the pond will hold several rare aquatic plants typical of the Castelluccio plateau).

A ten years old system treating the wastewater produced by a winery in Central Italy. Cecchi is a famous wine producer in Italy and the production is certified ISO14001; all the wastewater produced by the "bottling department", located in Castellina in Chianti, Province of Siena, is appropriately treated before to be discharged in a nearby stream by a multistage constructed wetland.
