in some areas, the two wells have to be at least 100 feet apart
in an open loop system, water drawn from the first well is discharged into a second well after it is used

Generated explanation

The illustration shows a well-based, open-loop water-source heat pump serving a house. Arrows show groundwater rising from a supply well through an intake pipe to the compressor/heat exchanger unit, which is connected to an indoor coil. Used water travels through a discharge pipe into a separate discharge well rather than returning through a closed loop. The drawing indicates a well separation greater than 100 feet and notes that at least 100 feet is required in some areas. Supply well water is labeled as typically 40°F to 50°F year round.
