Teeside: A 1000 m2, 3 stage passive vertical flow reed bed system, treating run off from an international airport fire fighting training facility.
Septage treatment plant of Nègrepelisse with reed bed filters and reuse of the treated leachates to irrigate a Short Rotation Coppice. Capacity : 3500 septic tanks or 11000 m3/year equivalent to 131 T of SS/year. Designed and built by Epur Natur.
Aerated wetland of 360 m², treating the sanitary waste water from an elementary school.
In 2001, IRIDRA managed the design of a constructed wetlands system for the wine-producing firm “Tenuta dell’Ornellaia”, Leghorn, Italy. The system consists of vertical flow constructed wetlands (SFS-v) as a first stage followed by a second SFS-h stage with recirculation to the first stage and then by a single FWS. It treats wastewater from the firm, which allows water to be reused for irrigation

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).
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.
