Abstract

Water is an, important component for life and it needs to be assessed at all stages in order to ascertain its safe usage. Keeping in view the importance of water, the waste water samples were collected, from major waste water drains (i.e. Shahi Khatta, Muhammad Zai and Hazar Khwani drain) of Peshawar City and were assessed for its quality characterization. Total 24 samples of water on hourly basis collected from each site were analyzed for physicochemical parameters like pH, Color, TSS, Total, TDS, COD, BOD, Oil and Grease, SO4_, S-2, NH3and Cl-. The results showed that concentrations of TSS, COD, BOD, Sulphate and sulfide were well above the permissible level of the National Environmental Quality Standards of Pakistan and needs treatment before its discharge into the river water. Ways and means of wastewater reductions needs to be identified to reduce the cost of waste water treatment.
