    The quality of drinking water always considered as a highest significance field for the researchers worldwide as it has direct impact on the population's lives. In Fallujah city- Iraq, this research was conducted to evaluate the water quality & the performance of generally and the WQPs particularly to identify the significance or the impact to number of fourteen parameters which have direct impact on the quality of drinking water. The survey carried out with 32 experts working in the same field. The assessment of the WQPs in the survey conducted based on the Likert scale 1-7. After that, The RII calculation were implemented on the primary weights to extract the weights that required for the TOPSIS method. Then, the two Fuzzy scales (1,2,3) & (0, 0.1, 0.2) applied on the survey and RII results to create a second layer of generating the MCDM\TOPSIS weights. Then, the TOPSIS method executed using Octave software where three variables were created which represents the decision matrix taken form the WQ testing results of these WTPs, the final weights which generated using the both approaches of the two fuzzy scales, and the beneficial & on-beneficial values that identified using the water quality parameters scale. The results of TOPSIS method reveals that the final ranking over the six months using both Fuzzy scales gave the similar ranking for these WTPs.
