1. First, the cement floor is changed into a permeable material: the permeable material can allow water to penetrate into the ground, and the water will precipitate after contacting with underground sediments, thus achieving the filtering effect. This helps to reduce water flow, reduce water accumulation on the ground, and also help to reduce the pressure of the pipeline.
2. Secondly, build a clear water pool: connect the drainage ditch to the clear water pool, and place a sedimentation tank and plants in the clear water pool. Sedimentation tanks can precipitate impurities, while plants can absorb some pollutants.
3. Finally, build new drainage pipes: build new drainage pipes in the backyard for drainage treatment.
