    Abstract: In attention to healthy risks of effluent discharge of wastewater from treatment plants to water sources and use in agriculture, this study was carried out for quality assessment of effluent discharge from Tehran wastewater treatment plant Tehran, Iran in 2010. For this investigation, according to Iranian EPA standard’s procedure, the mixing sampling method was carried out from effluent >24 h and some of physical and chemical characteristics of sample measured by standard methods. TS and TSS had been minimum and maximum removal, respectively (35 and 97%). TS of the outgoing wastewater in all plants exceed the standard rate and the rate of COD, BOD and phosphorus in the outgoing wastewater is mild and fall within the range defined by Department of Environment and WHO.
