In 2011, all groundwater using it as a source of drinking water in metropolitan regions of Iran were subjected to a novel “drinking water quality index (DWQI)” developed as “Modified DWQI” and based on the Canadian DWQI. The input parameters are modified in DWQI by having weighting factors applied. Twenty-three water quality characteristics and pertinent Iranian requirements for drinking water were chosen as model parameters and criterion, respectively, in the creation of the updated DWQI. The hyperparameters, the number of assessments throughout the dataset conveying the criteria, and thus the amount of deviation from the benchmarking in the violator observations are used to generate the adjusted DWQI for each sample location over the course of a year. The health-based index “Modified HWQI” and the acceptance index “Modified AWQI” are the two sub-indices that make up the modified DWQI. With a scale from 0 to 100, the updated DWQI and its subindices divide water quality into 5 categories: bad, marginal, fair, good, and excellent. The case study’s findings showed that the adjusted DWQI, HWQI, and AWQI scores for groundwater resources across the country were, respectively, and that the overall water quality status in groundwater recharge was well described. This paper discusses various defuzzification techniques as well as how to compute the distance between the two fuzzy integers. The MOORA method’s ratio structure and good reference approach can be applied in confusing settings by employing these techniques. The proposed adjustment makes the MOORA approach applicable to a wide range of real-world issues. An example of machining circuits designing process is taken into consideration to show the applicability and efficacy of the suggested approach. The alternatives are Albany, Bunbury, Perth and Geraldton. the Evaluation parameters are Mean TDS (ppm), Annual Range (ppm), Minimum (ppm) and Maximum (ppm). The final rank of this paper the Albany is got fourth rank, Bunbury is got third rank, Perth is got second rank, Geraldton is got first rank. The final result is done by using the MOORA method.
