Assessment of water requirements of crops for the reuse of municipal wastewaters from the wastewater treatment plant at Patras, Greece

The possibilities of reuse, for irrigation, of the treated wastewaters produced in the biological wastewater treatment plant at Patras, Greece, have been examined. The practice of water reuse in soils, and cultivation, releases large amounts of water that are very useful to areas that face water shortage; it also contributes to the protection of the water ecosystem. The suggested safe reuse in seaside Mediterranean cities such as Patras will be the commencement of irrigation with treated wastewaters in other cities where there are areas with important primary production.
