The invention provides a monitoring method of domestic life water consumption. The monitoring method comprises the steps of determining the quantity of domestic life water consumption terminals; making a water consumption type recording table; installing flow metering equipment in front of the domestic life water consumption terminals, and numbering the flow metering equipment; according to domestic life water consumption time, water consumption counted by the flow metering equipment, the serial number of the flow metering equipment and the domestic life water consumption type, filling the water consumption type recording table; selecting a preset monitoring time period, and conducting consecutive monitoring experiments. The monitoring method of the domestic life water consumption is novel in thought and simple in principle, and can achieve on-line monitoring of all the domestic life water consumption.
