The Leoni Waste Water Treatment Plant (WWTP) provides sewage disposal services to thirteen communities, which comprise the Leoni Regional Utility Authority (LRUA). Members of the LRUA are the Townships of Leoni, Napoleon, Columbia, Norvell, Hanover and Liberty, the Charter Townships of Blackman and Grass Lake and the Villages of Grass Lake and Brooklyn which are all located in Jackson County, as well as the Township of Cambridge, located in Lenawee County and the Townships of Sylvan and Lyndon, located in Washtenaw county. In addition to sewage collection and disposal service to the LRUA, the Leoni WWTP accepts septage, from septic tank pumping, from Jackson County, and an area within a radius of 25 miles of the treatment plant located at 8401 Page Avenue, Leoni Township, Michigan. The new Leoni WWTP replaces a lagoon treatment system, capable of treating 2.6 million gallons per day (mgd), which was nearing it’s design capacity and was unable to meet new and stricter discharge limits imposed by state regulatory agencies. The new plant will initially be able to treat sewage at an average daily rate of 3.0 mgd and may, in the future, be expanded to treat a total of 4.0 mgd. Sewage is pumped to the Leoni WWTP, from sewer lift stations in the various LRUA communities, through a series of force mains where it enters the Headworks of the WWTP. At the Headworks, grit is removed from the waste stream and the wastewater is screened to remove inorganic material and reduce the solids to a diameter of 2 millimeters or less. The waste stream moves to the Anaerobic Basins where anaerobic (without oxygen) bacterial action takes place to begin to treat the wastewater. The next step in the process is the Pre- Anoxic Basins where the wastewater is continuously mixed and some oxygen is added to the sewage and Aerobic (with oxygen) bacterial activity begins to occur. To this point, all the movement of the waste stream has been by gravity. The wastewater is now pumped from the Pre-Anoxic Basins to the Pre-Aeration Basins where large quantities of air and oxygen are added to the waste stream resulting in a completely aerobic condition for continued treatment. The waste water, again moving by gravity, travels to the Membrane Reactor Basins (MBR) where state of the art Membrane Filters remove the solids and particles, as small as a polio virus, from the waste water. Additional air and oxygen is also added in these basins. The filtered wastewater, now called Final Effluent, travels through a series of pipes to the Final Effluent Pumping Station. Final Effluent Water is disinfected by Ultra-Violet (UV) Light, aerated to add additional oxygen to the water as the effluent cascades down a series of steps and is then pumped to the Grand River, by three Vertical Turbine Pumps. The final, treated, disinfected and oxygen rich water is pumped through approximately 4.5 miles of newly constructed sewer main, where it outfalls into the Grand River just west of the Fifth Street Bridge in Michigan Center.
