How is the sewage treated?

The treatment plant was upgraded in 1998. It is capable of treating 1.25 million gallons per day during dry weather and up to 4 million gallons per day during wet weather. An activated sludge process is used followed by effluent filtration. Ultraviolet (UV) light is used to disinfect the treated wastewater eliminating chlorine disinfection, which tends to harm beneficial aquatic species.
