Wastewater from seven slaughterhouses was evaluated in terms of quality and quantity. Effluent Samples were obtained from the slaughterhouses outlet channels and analyzed for Temperature, Electrical Conductivity, pH, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Total Solids (TS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonium Nitrogen (NH4-N), Nitrate Nitrogen (NO3-N), Nitrite Nitrogen (NO2-N), Phosphate (PO43-). Results show that the current effluent quality from the slaughterhouses is not suitable for discharge into surface water. The physicochemical wastewater parameter values were very high such as values of 3144.8±251.07µS/cm for Electrical Conductivity, 1667.8±127.58mg/l for Total Dissolved Solids, 1049.3±235.75mg/l for Biochemical Oxygen Demand and 1698.9±291.91mg/l for Chemical Oxygen Demand. The study also revealed a serious water economy at the facilities.
