| Summary: | Micro-hydropower is a most sustainable source of energy that may generate 2kW to 100kW of electricity. The production of electrical power of micro-hydropower is from kinetic energy converted into electrical energy by the flow of water through a drain or channel and distribute to the desire location. In urban areas, micro-hydropower is generated through the flow of water from surface runoff. The source of flow is surface runoff on the impermeable layer that contain particles and suspended solids. These particles and suspended solid are unfavourable for the turbines used in micro-hydropower as they may slow the rotation, thus decreasing the generation of electricity. Filter media is a significant component in micro-hydropower. Stormwater will permeate through the filter media and the flow will rotate the turbines to generate electricity. In this study, stormwater is treated through filter media of pervious concrete and scoria rocks. It is expected to improve the efficiency of the turbine rotation. This is important in maintaining the production of electricity through micro-hydropower. © Published under licence by IOP Publishing Ltd.
