A small hydropower generator harnessing the waters of a river, an agricultural waterway and city water services is a power plant that generates 1,000 kilowatts of electricity. A small hydropower generator using river water and agricultural water is inefficient, due to the restriction of flow resulting from fallen leaves and garbage. Using city water services takes advantage of a cleaner flow free of fallen leaves and garbage. In addition, the advantage of the small hydropower generator using city water services is that the rate of operation is higher than a photovoltaic power generator, which depends on daylight hours. The small hydroturbine is able to turn continuously, and it can generate electricity at all hours, but the output is smaller. The final aim is to generate electricity by setting up small hydroturbine in pipes of small internal diameters, like are present in city water services. This study is on the manufacture of a small hydroturbine and an analysis of the flow field with a high-speed camera.
