2-stage vertical flow reed bed filter treating raw domestic sewage (French system) with a capacity of 650 P.E. Treated effluent goes through a filtering ditch and is rejected into the river Bourdic.

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
