Full scale pilot plant treating CSO overflow in the Greater Lyon area.
Beautiful two stage French system treating the wastewater of a hamlet in the outskirts of Paris
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.
Resolis: Two 200m2 horizontal subsurface flow wetlands operated in paralell treating 10m3/d of secondary sewage.
Hollange : a 432 m², vertical flow reed bed (French system) plus a 288 m² second stage unsaturated vertical flow filter, and a 1200 m² vegetated polishing zone treating 102 m3/d of domestic effluent.
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).
At Escurolles, in central France (Allier), a reed bed fed with raw sewage assures primary and secondary treatment for 705 PE , followed by a tricking filter for polishing and nitrification
Bauduen : a 2-stage Vertical FLow reed bed filter (French Design) for the treatment of domestic effluent from a village with variable population. A UV tertiary treatment ensures pathogens removal for protection of the bathing area in the lake downstream.
Balhall: A two stage, 185 m2,Aerated saturated vertical flow reed bed system treating 5 m3/d of settled, secondary sewage.
