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
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.
