Recycled Water &
the Wastewater Treatment Process

In the initial phase of treatment, screens and grit chambers remove large solids as well as sand and gravel, protecting the remaining treatment infrastructure from excessive wear and damage. The wastewater then flows to the aeration basin where microbes biologically break down the organic matter. After aeration, the water flows to the sedimentation tank where the water is separated from microorganisms and solids that settle by gravity. The water then receives a chlorine injection to destroy remaining bacteria or microorganisms. Finally, the water receives advanced treatment to remove very fine solids and particles. The bio-solids produced by the process are dewatered and disposed of in a sanitary landfill. The recycled water is then stored at the PSD’s Recycled Water Plant on Oak Park Drive, pumped to designated lagoons and tanks at golf courses, or sent to the wetlands.
