The reuse of treated wastewater represents an attractive prospect for sustainable water management in urban areas. The aim of this study was to evaluate the reuse of treated wastewater from constructed wetland systems for the irrigation of Seashore paspalum turf (Paspalum vaginatum Sw.) and assess the effects of treated wastewater on the soil and turfgrass. The research was carried out in Sicily (Italy) in a pilot-scale horizontal subsurface flow system (HSSF). Seashore paspalum plots were irrigated with freshwater and treated wastewater. In treated wastewater-irrigated plots, we estimated the amounts of nitrogen and potassium, supplied by irrigatingwith treated wastewater. The productive and qualitative characteristics of Seashore paspalum were not significantly influenced by irrigation with treated wastewater compared to freshwater. There was no significant variation in soil salinity and organic matter with the application of treated wastewater. The results confirm that treated wastewaters provide an additional water source and fertilizer for turf management in urban areas where the supply of freshwater is often limited.
