The document outlines the specifications and components of the man-made river project supporting the Ghadames water system, including various structures such as air valves, drain valves, pump wells, and more. It details the materials required, specifically types of steel reinforcement and concrete mix, as well as the installation processes, such as prefabrication and corrosion protection measures. Additionally, it notes the pressure rates (6-26 bars) required for the concrete conveyance line.
