2-stage Vertical Flow Constructed Wetland for the treatment of raw domestic sewage (French system) for 1360 people-equivalent adapted to the local resources and climate with UV tertiary treatment.

20 years old French system serving 200 p.e. in the Lyon area

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).

The municipal centralised treatment plant (a classic activated sludge technology) for the wastewater produced by the municipality of Jesi (Ancona province – central Italy) has been upgraded in the year 2002, with the realisation of a new “nitrification-denitrification” compartment and a hybrid Constructed Wetland as polishing stage. 

Saint Bonnet le Froid : a 900 m², vertical flow reed bed (French system) plus a 600 m² second stage unsaturated vertical flow red bed for the treatment of  domestic effluent from a village with variable population.

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

Vertical flow wetland, 75 PE for an ecological housing project in Arnhem, the Netherlands.

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. 

Pouembout : a 250 p.e. reed bed filter was created to replace a deficient waste stabilization pond.

One of the largest and most efficient wastewater treatment plant with french system reed bed filter in France.

Nominal capacity : 4000 p.e. with an extension to 6000 p.e.
