  • Soil infrastructure systems for sustainable and integrated economic and environmental performance
    Patent number: 10077914
    Abstract: Environmental enhancement systems and methods are disclosed. The environmental enhancement system may include a ground source heat pump including a subsurface ground loop portion and a liquid supply system to apply liquid (e.g., wastewater) to soil that is proximate to the subsurface ground loop portion. Performance of the ground source heat pump is improved by increasing heat transfer between the ground loop portion and the soil that is proximate to the subsurface ground loop portion. A gas injection system may be used to inject a gas into the soil that is proximate to the subsurface ground loop portion thereby cooling the soil, liquid, and air at a surface of the soil.
