Most small reservoirs in China were built during 1950s to 1970s, with low engineering standards and poor quality. Due to long-time operation, aging and lack of maintenance, there are many problems in small reservoirs, especially the leakage of drainage tunnel, which seriously affects the normal function of reservoirs. Taking the Huzhu East reservoir in Tengzhou city, Shandong province as an example, the feasibility of various seepage prevention techniques for the drainage tunnel is expounded. Based on the cost-effectiveness, the optimal seepage prevention technique scheme that meets the application conditions of the reservoir is selected for reference
