I see this term in geothermal usually meaning that an 'open loop' system is being used, and water is being drawn from the ground or river or other water source then heat is extracted and the water is then pumped on to a lake or a river or a different well where it is absorbed back into the earth.
Is this how you mean the process works?

Yes,
That is exactly what they do.
Pump fromthe ground water table (to an underground storage tank)
and dump back to the water table (through a leeching field).
Several of the units in my neighborhood have had their leeching field sink. (sinking field = mucho denero)
We live near the ocean and the water table is just below the surface..
