Abstract


The occurrence of water hammer in water supply systems usually damages the pipeline, unless suitable devices are used to regulate the excessive pressure head. However, this effect of water hammer can be utilized by installing appropriate turbines in water transmission pipeline. Hence, these study focuses on prototypes  development of pico-hydro turbine for energy generation along a water distribution networks, which have the ability of converting the potential energy of the flowing water in pipes to an electrical power at the lower end of the inter connected pipes. To achieve this, the pico-turbine was designed and fabricated, and the generator was selected. Afterwards, the turbine was tested through measurements of water heads and flow rate as well as power estimation. It was found that at a maximum water head of 30cm, the turbine generated a power of 0.92 watts, with maximum value of current and voltage of 0.344mA and 2.66V respectively. It has an overall performance of 88%. Further investigation are required on increasing the capacity and integrating a rechargeable battery within the pico-turbine systems.
