The invention provides a bundle type water bag which is used for recycling and reusing domestic water. The bundle type water bag is structurally composed of a bag body, a ribbon, a hose and a self-priming pump. The bag body is a soft cylinder body. The bag body is bundled to a main lower water discharge way. The bottom of the bag body is connected with a segment of hose. The hose is hung on a bag opening through a hook. The upper end of the bag body is provided with the self-priming pump. An end opening of a water outlet pipe of the self-priming pump is fixed into the bag body. A segment of thread hose is adopted for a water inlet pipe of the self-priming pump so that the water inlet pipe can be put into a container containing water conveniently. When water storage is conducted, water is pumped into the bag body through the self-priming pump or directly injected into the bag body through the bag opening. When water is used, water is poured to be used for washing just by taking down the hook on the hose directly, and the bundle type water bag is very practical and convenient to use.
