The system comprises a drainage pipe, a shallow foundation pit and water storage ponds. The shallow foundation pit sequentially comprises a vegetation layer, a covering layer, a planting soil layer, a sandy soil layer, a gravel layer and a medical stone layer. The water storage ponds comprise the first water storage pond and the second water storage pond. One end of the drainage pipe extends into the vegetation layer in the shallow foundation pit, a second water pipe is connected with one side of the sandy soil layer, and a third water pipe is connected with one side of the gravel layer. Water on a roof is discharged by means of a J-shaped guide pipe, and the problem that pits appear during water discharge achieved through an existing I-shaped guide pipe is avoided. Rainwater is introduced into the shallow foundation pit through the drainage pipe, the rainwater is filtered and s
