Case Study: Milton Regional Sewer Authority reduces its carbon footprint with Cummins gas generator sets

Waste Water Treatment Plant Reduces Its Carbon Footprint With Reliable Gas Solution

Milton Regional Sewer Authority (MRSA), a wastewater treatment plant in Pennsylvania, wanted to reduce its carbon footprint while continuing to handle residential, commercial, and industrial waste effectively. To support its Wastewater to Energy upgrade, it needed a reliable combined heat and power solution that could turn digester gas into useful electric and thermal energy.

Cummins supplied and installed 2 x C1000N6C QSK60G low-BTU digester gas generator sets for continuous CHP operation. The system uses jacket water heat to warm the digester tanks and exhaust heat to dry sludge, while electricity is exported to the local utility and repurchased as renewable energy, helping MRSA cut emissions, reduce solids hauling costs, and utilize about 4.25 MGD of wastewater capacity more efficiently.
