ResumoStabilization reservoirs are hypertrophic aquatic systems functioning under non-steady-state conditions. The use of stabilization reservoirs is especially suitable for warm countries suffering from water shortage, where regulation between wastewater production and effluent utilization is needed. Stabilization reservoirs can significantly improve effluent quality; however, only few models have been developed to date. Today, with growing demand for high quality effluent, better understanding of the processes occurring in the reservoirs is needed. This paper describes the development of a mechanistic simulation model that integrates knowledge from the fields of wastewater treatment and limnology. The model has five quality variables in the waterbody and two in the sediment. It was calibrated and verified on three stabilization reservoirs in Israel and exhibited good agreement with observations. Different design and operation alternatives were studied, and some are discussed in this paper. The prediction ability of the model turns it into a useful research and design tool for studying the influence of various design and operation alternatives on the reservoirs’ efficiency as wastewater treatment units.
