Abstract: Grey water use is important because it restricts fresh water demand and reduces stress on treatment system. Therefore, it is the last option for the water conservation. The main goal of this study is to estimate and characterize the quality of grey water produced form households in Karbala city during the year of 2018. The study shows that the quantity of grey water produced from different sources in a chosen household in Karbala city was 170 L/c.d which was account about 37.8% of the proposed quantity of drinking water supplied by the municipality for urban areas (450 L/c.d). The results show that the lowest concentrations were observed in August which were (84 NTU), (194.9 mg/L), (480 mg/L), for Tur., Cl and T.H, respectively. While for TDS and Ca were (749 mg/L) and (240 mg/L), in July. Also, the lowest value of COD, BOD and Mg were (179 mg/L), (117 mg/L) and (43.74 mg/L), respectively, in June and the pH was 7.1 in March.
