Investigating carbon footprint of drinking water supply system in sepidan

Human environmental impacts on the earth can be examined in various fields. One of the areas of great importance is carbon dioxide emissions by human. One of the thousands of human activities that lead to carbon dioxide emissions into the environment is the supply of water. This paper examines the amount of carbon dioxide released by the drinking water supply system in Sepidan. This project took place within a year's time. The results of the surveyes show that in Sepidan, from one well with an energy consumption of 81318 kwh, one spring with an energy consumption of 102234 kwh, and the building of water and sewage organization with an energy consumption of 5491 kwh, amounting to 1067, 48,769 and 3293 kilograms of carbon dioxide release per year. Also, the results showed that 38 grams of carbon dioxide is produced for the supply of one liter of drinking water in the Sepidan. The results of study showed that the supply of water from the spring at a higher altitude point than areas of the city due to the specific topography of the Sepidan, Which is in the form of sloping, requires much less energy, and releases less contamination or carbon Dioxide.
