 Background and Purpose: Supply of high-quality water (drinking water quality), is a critical component for sustainable socioeconomic development. This study aimed to assess the current state of water quality supplied to the distribution system and importance of participating water and sewer its distribution network to improve the quality selected.

Materials and Methods: This cross-sectional study in 1394 in both spring and summer, during a systematic search, local information on the quality (microbiological, physical and chemical) drinking water distribution systems were evaluated using a questionnaire. The samples for the presence of CL, PH, TDS, sulfates, total hardness, nitrite, nitrate, fluoride, chloride, turbidity and total coliform were analyzed by standard methods and 1053 were compared with the national standard.

Results: The average parameters studied a total of 303 water samples collected from amount CL, PH, TDS, sulfates, total hardness, magnesium, calcium, nitrite, nitrate, fluoride, chloride, turbidity and total coliform respectively equal Was reported 0/1 mg/L, 7/66 mg/L, 773/39 mg/L,108/15 mg/L, 287/84 mg/L, 31/59 mg/L, 50/05 mg/L, 0/02 mg/L, 19/56 mg/L, 1/08 mg/L, 80/57 mg/L, 0/6 mg/L, 24/5 MPN/100ML. The role of water and sewage company as well as the effect of the drinking water distribution network respectively physicochemical and microbiological quality of drinking water in the utility had a significant relationship (p <0/005), (p <0/0001). And significant relationship between the quality of water supplied by the technical infrastructure and health, fatigue and corrosion, leakage and pressure was high hydro Leakey (p <0/000). According to the results of the statistical test Pearson and Spearman correlation coefficient also showed a strong correlation between the leak with water quality.

Conclusion: The results showed that the water samples tested for microbial and physico-chemical parameters were within the range of Iran's national standard 1053 except the CL, which is less than the national standard. The role of water and sewage company distribution network and improve its quality is very important.
