Ground-water gradients as high as 120 ft/mile exist at the edge of a buried glacial sluiceway in northwestern Indiana. A theoretical feasibility study showed that if an upgradient extraction well were connected by siphon pipelines of different diameters to a reinjection well one mile downgradient, with a 10,000 square-foot commercial building using a ground-water heat-pump system between them, then the following could be expected: (1) for a siphon diameters of four and six inches, the siphon/heat pump system would posses the lowest present worth of total life-cycle costs of all other conventional heating and cooling systems and would be the least expensive system to operate each year; (2) the increased capital expenditure of installing a siphon-heat pump system vs. gas, oil, or electric systems would be recovered during the 20-year life-cycle of the system for both siphon diameters. Aquifer systems with high hydraulic gradients in many parts of the world could be utilized thusly to provide cheap and environmentally-clean supplementary energy sources, and therefore, reduce dependence on fossil-fuel supplies.
