Study of non-isolated urban burned solids site improper local on water Resources and contribution networks NRW Amount (Rostamabad City, Guilan province, case study)

One of the the most important causes of Non-Revenue water is waste of water reduction. The factors, damaged consumers meters or lack of precision meters due to the presence of sediment resulting from chemical changes. Of the reasons for these changes can pointed to penetration the garbage leachate to water resources. Sediment or corrosive features water distribution network (the quality of the chemical) would be on the amount of waste-water supply network will be more effective. Rostam abad town landfill is in the Western town of drinking water sources and above of underground water resources. In this study, the process route of chemical quality parameters for Rostamabad in the past five years, was analyzed, the potential of corrosive and sediment of water according to the Langelier & Ryznar index was calculated. The changes of chemical parameters, respectively, of the total hardness and calcium, total Alkalinity, electrical conductivity, pH, sulfate and chloride origin years (1390-91) and the target years (1394-95) is compared. Due to the increase of qualitative parameters, in spite of that it seems that their impact is laid waste leachate, but still within the scope of the national standard and the WHO (World Health Organization). Study of corrosion and sedimentation of index values indicate that the water is a little balanced in terms of chemical quality and has low precipitation and weak. The impact of quality changes is increasing and must be taken seriously.
