This paper mainly discussed whether soil water repellency will reoccur or not shortly after the soil is irrigated with sewage, which the water-repellency soil is eliminated by the physical method. Drip irrigation is adapted for the water-repellency soil with tap water and other three domestic wastewater. The significance of Water Drop Penetration Time was checked after irrigated in 4 and 8 months. The result shows that soil water repellency will appear again after drip irrigation in a certain intervals. Meanwhile, it has a significant positive correlation with irrigation time and water quality.
