The sewerthermal heat and cooling system harnesses energy from treated water and supplies the Kirie WRP with up to 40 percent of its heating and cooling energy needs. This plan provides a model for heating and cooling energy needs at other MWRD facilities. The sewerthermal system will take advantage of relatively constant high temperatures of effluent water and will use only 20 percent or less power than what is needed for a traditional, direct heating system. Rather than extracting heat from the ground as is common for geothermal systems, the MWRD’s system is designed to extract heat from the effluent water, which holds a steady minimum temperature of 55 degrees Fahrenheit.
