The Fritz C. Dietrich Environmental Control Facility, Chesterton’s wastewater treatment facility, services the Town of Chesterton, Town of Porter and the Indian Boundary Conservancy District.
The facility can treat at a rate of 4.6 million gallons per day (MGD) diurnal flow and at a rate of 10 MGD during wet weather events.
The facility consists of a headworks facility with:
1 ultra violet disinfection chamber
2 primary anaerobic digesters to treat the primary and waste activated sludge
2 re-aeration units
3 final clarifiers
6 fine bubble aeration tanks
6 primary clarifiers
The digested sludge is transferred to a secondary digester for further treatment. The final process in this system is dewatering the sludge for land application at a local farm.
The Collection System includes 31 lift stations and more than 68 miles of sanitary sewers with pipe sizes ranging from 4 inches to 48 inches.
