UNDERGROUNG WATER SUPPLY SYSTEM

An underground water supply system having an induction groove which is opened on one side which gets to the pointed end part from the inlet port is provided. The system is simple in structure and easy to mold and thus reduces the manufacturing cost. In the conventional underground water supply system comprising a pumping device for pumping water in a storage tank, an inlet port(12) for supplying the pumped water to the ground and a water supply device(10) with a pointed end part(13) at the lower part, an induction groove(20) is formed at the lower part of the inlet port and opened on one side which gets to the pointed end part. A main hose has a plurality of connecting holes and is connected to the pumping device. A scale(15) is formed the outer peripheral surface of the water supply means to indicate the depth.
