The Goupitan Hydropower Station is a key project of the national "10th Five-Year Plan" and a landmark project in Guizhou's implementation of the "West-East Power Transmission" strategy. Sinohydro Foundation Engineering Bureau undertook multiple tasks including the left-bank seepage control works of the hydropower station's seepage control project, improvement of the Lannigou drainage system, and treatment of slope deformation on the south side of the tailrace. In curtain grouting construction,fully adopted small-diameter full-section diamond drilling technologysignificantly improving construction efficiency.

    The Silin Hydropower Station is located on the main stream of the Wu River in Sinan County, Tongren City, Guizhou Province, and is the eighth cascade hydropower station in the cascade development of the Wu River main stream. It has a reservoir capacity of 1.205 billion cubic meters and an installed capacity of 1.05 million kilowatts. Sinohydro Foundation Engineering Bureau undertook construction tasks at the hydropower station includingK30, K31 karst treatment, and seepage control on the left bank of the dam, effectively eliminating geological hazards at the station and ensuring the safe and stable operation of the project.

    The Shatuo Hydropower Station is one of the "Four Rivers" projects in the second batch launched under the "West-East Power Transmission" program, and is the last cascade hydropower station in the Wu River basin cascade development and within Guizhou Province,hailed as the "dream-fulfilling project" of Guizhou's Wu River hydropower cascade development。The hydropower station hub is a Class II project, with a total reservoir capacity of 910 million cubic meters and a total installed capacity of 1.12 million kilowatts. Sinohydro Foundation Engineering Bureau undertook the grouting construction task on the left bank of the station.
