The Leoni Township’s wastewater treatment plant (WWTP) serves thirteen communities across three counties including the Michigan Speedway
complex. A moratorium on growth was put in place until capacity and treatment issues with an aging aerated lagoon system could be addressed. In June of this year, construction of a new membrane bioreactor (MBR) System was completed under budget and ahead of schedule. The new, higher capacity, plant will exceed current and future permit requirements allowing for new development in the service area,
protecting both public health and the environment.
The WWTP upgrade was designed to allow for phased installation keeping costs down and improving treatment efficiency over the life of the plant. In Phase 1, the plant will be rated to handle a nominal capacity of 3.0 MGD and short-term peaks up to 4.8 MGD. Accommodations were made for the installation of additional equipment, as needed, as fl ows increase over the life of the plant.
