Disclosed is a water treatment apparatus (100) which can extract clean water by means of the pressure of raw water. The disclosed water treatment apparatus (100) comprises: a filtering unit (200) filtering raw water; a storage member (300) including a first chamber (310) and a second chamber (320), wherein a volume of the second chamber (320) is reduced when the purified water is supplied to the first chamber (310) and a volume of the first chamber (310) is reduced when the concentrated water is supplied to the second chamber (320); an extracting member (700) configured to supply the purified water to a user; an air supply conduit (AP) disposed on a flow path connected to the first chamber (310) of the storage member (300), and configured to supply air to the first chamber (310) of the storage member (300); and a flow path conversion valve (400) configured to convert the flow path to allow flow of the purified water into the first chamber (310) or allow discharge of the purified water from the first chamber (310). When air is supplied to the first chamber (310) through the air supply conduit (AP) after the purified water stored in the first chamber (310) is discharged, the volume of the first chamber (310) is increased and the volume of the second chamber (320) is reduced as the first chamber (310) is filled with air, and water accommodated in the second chamber (320) is discharged by reducing the volume of the second chamber (320), thereby emptying the second chamber (320) of water.
