Abstract: Treated wastewater is frequently used as an unconventional water resource because water resources are important to preserve the environment and human health, particularly in arid and semiarid regions. The present work examined the suitability of treated wastewater from Sasso basin in Misurata City, Libya for agricultural irrigation. Physical, chemical, and biological characteristics of treated wastewater from Sasso basin during a six-month period were monitored twice a month and compared with Libyan, FAO, WHO, USEPA, and USSL standards. Quality indicators of treated wastewater were higher than the acceptable ranges of national and international standards. Treated wastewater from Sasso basin was not recommended for agricultural irrigation. The performance of the Al-Sikt Wastewater Treatment Plant should be rehabilitated and evaluated periodically before considering treated wastewater for irrigation. We suggest the use of secondary treatment methods such as constructed wetlands to improve treated wastewater quality from Al-Sikt plant.
