PURPOSE: A parabola type aqueduct is provided to prevent water from spattering to the outside of a washstand by making water discharge to a concave part of a washstand in a parabola, to clean up easily by excluding a hydrant and to heighten space utilization. CONSTITUTION: The parabola type aqueduct comprises: a washstand(10) provided with a concave part(11) to receive water for use and a drain outlet(12) formed on the lower part of the concave part(11); many discharge pipes(20) descending the water discharged from a discharge port toward the concave part(11) of the washstand(10) in a parabola by locating many discharge ports on the upper side of the washstand(10); a solenoid valve(30) installed on the discharge pipe(20) to control the quantity of the water discharged through the discharge port.
