Abstract: A hydropower installation includes a water supply and an energy generating station, with the supply at a higher level than the energy generating station; and a duct extending between the supply and the energy generating station. The energy generating station of the hydropower installation is configured based on high water velocity and low pressure. The duct may comprise plastic pipes. The duct may be arranged on a foam support and enclosed by a foam embedment. The duct may comprise at least two duct sections, with an intermediate energy generating station arranged between the duct sections of the duct. The duct may comprise internally extending protrusions, such as dimples to promote a laminar flow of fluid through the pipe. The duct may taper. Water pressure inside the duct may be maintained at atmospheric level. The proposed features all contribute to a pressure free velocity based system.
