A multifunctional integrated structure for rainwater utilization integrates rainwater storage, purification and pressurized water supply, and is especially suitable for small and medium-sized rainwater utilization projects. The structure consists of an inlet well, an outlet well, plastic module combined water tanks, a rainwater infiltration layer and another plastic module combined water tank. Rainwater enters the inlet well and is stored in the plastic module combined water tanks, then purified through the infiltration layer from the bottom of the tanks and collected into the outlet well. A submersible water supply pump can be activated to supply water to users at any time. The integrated structure is compact, easy to construct, occupies little space, is convenient to manage and facilitates automation. The plastic module combined water tanks are assembled quickly and can be disassembled for reconstruction elsewhere or recycled, protecting the environment and land resources. The infiltration layer purifies rainwater through slow filtration, saving water without power consumption.
