Background & Aims of the Study:  Corrosion and scaling are the most common problems of water facilities. Corrosion imposes many financial and health loss on system and consumer respectively, scaling also causes clogging and head loss in network. The purpose of this study is to determine the corrosion and scaling potential of water supply sources of Qom villages. Materials & Methods This cross-sectional study was done in 12 months (from 2011-2012). 100 samples were collected to determine pH, total dissolved solids (TDS), temperature, alkalinity, Calcium hardness and residual chlorine, and water corrosion and scaling have been studied by using Langelier, Ryzner, aggressive and Puckorius indexes. Results:  The results illustrate that Qom village water according to the Langelier index equals 1.62 (±0.11), according to Rayzner index equals 10.5 (±0.17), based on Aggressive index equals 12.035 (±0.14) and based on Pokurious index equals 9.92 (±0.13) respectively. Comparison of four index’s were showed that Water conditions in all villages of Qom is in corrosive range. Conclusions:  According to this study, water supply in Qom village is corrosive, one of the effective ways for solves this problem is pH adjustment by lime
