In order to effectively increase the amount of available groundwater resources, a method of artificial recharge is innovated. Based on the analysis of subsurface drip irrigation techniques and the method for artificial recharge of groundwater, the constructive idea of underground pipe artificial recharge system was put forward. The groundwater reservoir in Tailan River was taken as a case to calculate the quantity of artificial recharge. The advantages, disadvantages, and the main points of structure design of the underground pipe artificial recharge system were discussed. The results show that the new method can reduce the soil moisture of the surface soil and land evaporation effectively. At the same time, the case study in Tailan groundwater reservoir shows that the amount of infiltrating water can reach about two million and two hundred thousand cube through a 10 kms subsurface pipe, which provides a powerful guarantee for artificial recharge of groundwater reservoir. In general, the system is a new method for effective utilization of water resources, it is of vast importance to the security of water use and the achievement of reasonable allocation of water resources. © 2016, Jilin University Press.
