Abstract

Corrosion in water distribution systems is the primary reason for occurrence of damages in pipes, faucets, and metal joints in water supplying systems, and results in decreasing the useful life of concrete reservoirs at least down to half, 40 decrease of water transmission in the pipes, as well as damaging the pipes and building materials. In addition, the entry of the material resulted from the destruction of the pipes to water imposes serious risks for consumers. In this study, the corrosion indices of drinking water sources of Zahedan were investigated in 33 water samples of this city in 2015, and values of parameters such as pH, TDS, total alkalinity, hardness, sodium, calcium, water temperature and other chemical parameters were determined as well. Langelier, Ryzner, and Puckorius indices were formulated in "Microsoft 2016" software to determine the qualitative parameters of the water samples, and the results were reported. The obtained results demonstrate 67.26, 78.72, and 100 of corrosion tendency for Langelier, Ryzner, and Puckorius indices of the samples, respectively. According to these results, the steel or concrete facilities of water transferring and distribution network of Zahedan have either already been damaged or will be. Considering the high degree of corrosion, the drinking water sources of Zahedan befit damping their corrosively. © 2016, Institute of Integrative Omics and Applied Biotechnology.
