Limited by weight and volume, the transportation and on-site installation of steel bifurcation in the diversion system of pumped storage power station have become a big problem in the construction of the project. According to the needs of the installation and construction of large 800 MPa steel bifurcation in the complex environment, combined with the characteristics of the transportation and installation in the tunnel, the unloading of steel bifurcation is carried out by using the bridge crane between the installation of underground powerhouse. The hoisting up-anchors and sliding trolley arranged in the tunnel are used to place and install the steel bifurcation, which solves the difficulty of hoisting and installing the large turnout pipe in the tunnel and has positive significance in saving the project cost and reducing the construction risk. In this paper, the construction technology of steel bifurcation is described under the complex conditions in pumped storage power station. Detailed description of steel bifurcation construction layout, assembly, site transportation and installation and other construction points, provide a feasible idea for the development of other similar projects.

: The sustainable use and management of freshwater resources is on the center of developmental debate and becoming a global challenge. The overall aim of this study is to document published literature in the field of water privatization, critically review them and to draw a conclusion about how private sector participation can contribute in the initiative of sustainability for freshwater. To accomplish the specific goal of this paper, review articles, research papers, mini-articles, book and reports of authorized organizations published from last 25 years were reviewed. Comparative advantages, problems, challenges and opportunities of private and public sector management in water resources were thoroughly analyzed. Based on those reviews
