Urban Wastewater as a Source of Reclaimed Water for Irrigation: Barriers and Future Possibilities

Water resources are under pressure worldwide, resulting in scarcity and deterioration of freshwater quality. According to European directives, we could reduce the on water urban areas by increasing reuse treated wastewater, reducing impact bodies, promoting recycling through multiple uses wastewater. Besides need address supply challenges, wastewater treatment systems show environmental stewardship innovative practices. Using reclaimed for agricultural irrigation is gaining interest because drought conditions experienced Europe over past few years. Furthermore, using may help restore nutrients (N P) natural biogeochemical cycles. This review highlights importance reuse, current legislation, existing technologies implement meet minimum requirements produce irrigation.
