All were achieved while also adding energy efficiency to the plant and reduce consumption: Solids are now further dewatered, reducing local truck traffic through adjacent neighborhoods; New methane gas cleaning system and associated heat and power system is 26% more efficient; High efficiency blowers installed reduces annual energy consumption by 26%. The expanded plant includes four Clarifiers, two Aeration Basins, two Pump Stations, a Grit Facility, Dewatering and Blower Building, and renovation of existing Clarifiers, Aeration Basins and Influent Pump Station & Screening Facility.
