Wastewater treatment facilities at high places can give chances for renewable and sustainable energy generation by putting hydroelectric turbines the input drain channels of wastewater plants, they also use sludge generated during process to make biogas, which be used generate power. Purified water is subsequently irrigate decorative plants along highways, in gardens, woods. The fermentation wastes are utilized as organic fertilizer improve agricultural soil quality. At Gharyan sewage station, a hybrid system consisting station an electric generator powered biogas proposed this research. This because city distinguished its location, approximately 713 m above sea level. results showed that would provide power 490 kW, sufficient cover 87.5% electrical consumption station. amount treated 13,000 m3/day, about 17 tons/day. investment value anticipated around $1,478,000, while cost producing unit expected 2.83 ¢/kWh. system's yearly net profit predicted $307,765. capital's recovery period 3.44 years. planned will limit discharge estimated 1,886 tons CO2 gas each year.
