On the ground, what provides pressure for the potable water system to dispense water?

Explanation:
The water pressure on the ground comes from a dedicated electric pump driven by an electric motor. This pump draws water from the potable storage tank and sends it through the distribution lines so you can dispense water at galley taps and in the lavatory, using the aircraft’s electrical power. Bleed air, hydraulic, or pneumatic systems aren’t used to pressurize the potable water supply on the ground, so they wouldn’t provide the needed pressure for dispensing.
