The present work goal was to evaluate the wastewater use potential for irrigation in Curitiba metropolitan area, Paraná State, Brazil. In order to evaluate the potential for wastewater use, effluent quality from main Sanepar sewage sludge plants was determined as well as the major soil class near to each station. Wastewater analysis indicated that the sewage sludge plants have good effluent treatment efficiency, but not enough to reach the water standard quality required for agricultural irrigation, mainly due to high BOD. The major soil classes found in the low land area were Histosol and Entisol which are more adapted for flood irrigation, due to poor drainage soil capacity. While, Ultisol, Inceptisol, and Oxisol are found in high land area, and they are more appropriate for sprinkler and localized irrigation. Commercial grain and vegetable production are the more promising crop groups to be irrigated with wastewater in this region.
