Saint Germain sur Ille : a 500 PE waste stabilization pond boosted to 900 PE by addition of reed bed filters with high standards for phosphorus and total nitrogen removal.

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
