Tigris River considers the main resource of water for Mosul city, therefore it is of great importance to  evaluate  its  quality  continuously.  In  this  study,  chemical  and  physical  properties  of  Tigris  River  had been  studied  within  Nineveh  governorate  during  the  year  (2012)  by  using  the  average  values  for  ten selected  sites.  Computing  of  Water  Quality  Index  (WQI)  was  done  by  using  Weight  Average  (WAV) method. In spite of the large amount of the wastewater disposed into the river, the results indicated that Water Quality (WQ) in all the studied sites  was suitable for irrigation purposes. For drinking purposes, only the first northern four sites were in need to simple treatment, while the following remaining sites need conventional treatment. The efficiency of the three main Water Treatment Plants (WTPs) on Tigris River were computed according to a new (WQI) that include new additional parameters and different relative weights.  These  three  plants  are;  Mosul  new  left  side  (WTP),  Mosul  right  side  monotheist  (WTP),  and Mosul old left side (WTP). The efficiency results were (70, 62, 55)% respectively. The Low efficiency of the old plant was due to the high effluent concentrations of turbidity, SO4, total hardness, and TDS.
