      Ya, usually liquids are compressed with air for any useful stored use. Otherwise something must continually pump. Maybe they are putting a large bladder into the ground?

        If I get it right, the ground itself is the impermeable “bladder”, as the water is pressed into rock. The rock maintains the pressure onto the water until it is being released.
