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

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).

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

A 2,400 m², vertical flow reed bed (French system), a 1,950 m² second stage vertical flow, unsaturated plus a 10,000 m² of willow plantation and a 5,000 m² pond treating 400 m3/d of domestic effluent.
