The use of reclaimed water for agricultural irrigation is practiced worldwide and will increase in the future. The definition of water quality limits is a useful instrument for the assessment of water quality regarding its suitability for irrigation purposes and the performance of wastewater treatment steps. This study elaborates water quality objectives for a water reuse project in a setting where national guidelines do not exist. Internationally established guidelines are therefore applied to the local context. Additional limits for turbidity, total suspended solids, biochemical and chemical oxygen demand, total phosphorus and potassium are suggested to meet the requirements of water reuse projects. Emphasis is put on water quality requirements prior to UV disinfection and nutrient requirements of cultivated crops. The presented values can be of assistance when monitoring reclaimed water quality. To facilitate the realization of water reuse projects, comprehensive and more detailed information, in particular on water quality requirements prior to disinfection steps, should be provided as well as regarding the protection of the irrigation infrastructure.
