What is the Wastewater System?web cover

The wastewater system has three parts. They are wastewater collection , wastewater treatment , and management of the effluents and solids resulting from the treatment process. Pumps, manholes, and pipes are components of the wastewater collection system. They are used to transport wastewater from homes and businesses in Sedona to the treatment plant located about five miles west of Sedona along SR 89A between Sedona and Cottonwood. The treatment plant uses basins, pumps, pipes, and ultraviolet lights in its treatment process. The treatment process the City uses is called an activated sludge process. This is a biological treatment process which accelerates the decomposition of wastes in the water using natural rather than chemically based process. The treatment process results is liquid (called effluent) and solids (called sludge). The management of these products involves the use of drying beds, centrifuges, large reservoirs, wetlands, and spray irrigations. Based upon tests conducted in 2013 injection of high quality effluent into the ground using wells will be used in the future.
