This study shows the results of a series of water balance measurements obtained
between 2012 and 2013 from a pilot HSSF system in the West of Sicily (Italy). The system was made by
two separate vegetated units: one with Arundo donax L. (giant reed) and the other with Cyperus
alternifolius L.(umbrella sedge), and fed with urban wastewater following secondary treatment from an
activated-sludge wastewater treatment plant
