The traditional way of water intake usually consumes electric energy, or requires high terrain and geological conditions, resulting in a large number of excavation and slope support, or pipeline crossing the impervious layer cause the damage of the impervious layer. Using the pressure difference between the upstream water surface and the inner pipe, the siphon can lead the water flow from the upstream, across the highland to the downstream, and avoid the pipeline crossing the dam to destroy the anti-seepage layer. It was a better way to take water. HDPE geomembrane was used to prevent seepage on the dam surface and reservoir area of an acidic reservoir. In order to avoid damaging the seepage control system and save energy, siphon pipes were designed for water intake and transmission. By introducing the calculation of water conveyance capacity and installation elevation of siphon pipe, and accounting data, it was concluded that the siphon pipe meet the requirements of the project.
