The present invention illustrates a water resource control system at home and a method thereof. In the system, a water pressure sensor and a flow sensor are respectively set up at a water outlet of a drain device and a bottom of the water outlet. A water pressure value and a flow value respectively measured by the water pressure sensor and the flow sensor are transmitted to a server. When the water pressure value is higher than a default pressure threshold and the flow value is higher than a default flow threshold, the server generates and transmits a water supply termination instruction to a control switch which is set up at a water inlet. The control switch then closes the water inlet according to the water supply termination instruction. Therefore, the technical effect of avoiding from wasting water resource can be achieved.
