Background: corrosion is a physic and chemical reaction occurring between a substance and its surrounding environment leading to the change in the substance properties. Corrosion can cause economic damage, loss of life and illness in consumers is watering plants. The aim of this study was to Assessment of scale formation and corrosion of drinking water supplies in Dehloran.

Methods: This research was a descriptive and cross-sectional study. the sampling was carried out during one year from 8 wells. Values of Langelier, Ryznar, corrosivity and Puckorius indexes were calculated by using such parameters as total dissolved solids (TDS), calcium hardness, total alkalinity, temperature, pH, pHs on all Sources of drinking water in dehloran.

Results: The results of this study showed that the amount of TDS, turbidity and total hardness wells is lower than the national standard. So that the highest and lowest TDS was obtained for Dashte Akbar 1wells (1084 mg/l) and Bare Bijeh 1(132 mg/l), respectively. As well as The highest and lowest turbidity was obtained for Bare Bijeh 2 wells (0.99 NTU) and Dashte Akbar 1(0.25 NTU), respectively. For all the wells studied was obtained Lanzhylh index between -0.43 to +0.19, Ryzner of the 7.52 to 9.07, Puckorius index between 8.69 to 11.21 and corrosion of between 8.01 to 8.68, respectively.

Conclusion: The relevant indicators show that drinking water in dehloran corrosive and therefore must be continuously monitored water quality in the distribution network and measures to be applied in the field of corrosion control.
