BNA Geothermal Cooling System

Nashville, Tennessee


Innovative Solution

Garver and the Nashville International Airport teamed up to turn an abandoned rock quarry into an asset that helps lower energy costs by more than $400,000 per year. Garver designed a pipeline corridor that sends water in a closed loop from the quarry reservoir to a cooling plant at the airport’s terminal. The largest geothermal cooling system of its kind in North America turns 79-degree water into 63-degree water as it travels the two-mile high-density polyethylene pipe, which crosses a runway and taxiway en route to the reservoir.
