With this study, we intend to contribute to the promotion of micro hydroelectric power plants for individual, family and community use. We pay a particular attention to sustainable and affordable solutions that could be used in isolated sites with relative less investment. For this purpose, we demonstrate the possibility of generating electricity from hydraulic energy of water flow in domestic taps and agriculture irrigation valves. Through examples of daily water needs of an average household and an irrigated farm, we estimate the electrical energy that could be generated by installing a suitable small turbine. In the case of irrigation water flow, the estimated quantity of electrical energy is relatively significant and could meet human basic needs such as powering and recharging daily household devices on isolated sites. The electricity is produced when the water flows. It is then necessary to store it in adapted batteries. We also underline the fact that the presented solutions are sustainable because the turbines recover an energy that was supposed to be lost.
