Abstract
The paper summarizes the current situation of urban wastewater treatment plants (UWWTP) in Turkey. Results of a detailed survey on the performance of four selected plants were given both in terms of influent and effluent quality and in comparison with the current legislation on discharge limits to receiving waters. All the selected plants were operating efficiently especially according to conventional control parameters and heavy metal content. The suitability of the effluents for irrigation purposes is then evaluated according to the existing national irrigation water quality standards. From the data inventory, it was evident that the current situation is not promising especially regarding the bacteriological parameter, i.e. fecal coliform. The main cause of this problem is either the lack of disinfection units and/or improper operation of the existing ones. Turkey, which has already established its irrigation water quality standards, however, needs to accelerate the reuse of effluents in irrigation in the most proper manner.

During the present study, water sampling and experimental analyses from both the influent and effluent of the treatment plants were accomplished, and the UWWTPs were evaluated based on their design capacities, type of treatment systems, effluent discharge methods and reuse potentials. Grab sampling and experimental analyses along with site visits were performed by The Scientific and Technical Research Council of Turkey – Marmara Research Center (TUBITAK-MRC) under the coordination of Istanbul Technical University (ITU) within the framework of the EC funded MEDAWARE Project where ITU acts as one of the project partners [6].
