A force main conveys sewage to the Inland Bays Regional Wastewater Facility where it is screened before entering a series of three partial mix aerated lagoons. Here, natural microorganisms break down the biological matter. Settable solids fall to the bottom of the lagoon and undergo anaerobic decay. The lagoons are 15 feet deep and are formed from earthen berms with a geocomposite liner and protective soil cover. Rip-rap slope protection stabilizes the freeboard area.
Treated water is disinfected with sodium hypochlorite and detention in a contact tank.
After disinfection, the effluent can be either stored in the 32 million-gallon effluent storage lagoon or pumped to the land application system. Inc. Corn, barley, soybeans, and wheat are grown on the irrigated land. The system uses naturally occurring microorganisms to purify wastewater in a series of lagoons. The reclaimed water is then recycled onto cropland. Soil provides final filtration and crops uptake the remaining nutrients.
