Abstract
A wastewater geothermal heat system is supplied with processed wastewater through a drip field in proximity to a thermal array part of a geothermal heat pump system. The wastewater treatment system portion provides a periodic source of treated wastewater. Several sensors and a control system regulate a pump that discharges wastewater from the treatment system and enters a drip field where it is released into the surrounding soil. The dampened soil provides an efficient vehicle to transfer heat into or out of a thermal array which is positioned adjacent to the drip field such that it is in contact with the soil that is dampened by the discharged wastewater.
