this paper a project based modeling og hydro power generation. the demand for electricity in residential sector is experirncing a strong growth and 16,283 million liters of water is being used in malaysia every day. with this large amount of water,it can be fully utilized to produce electricity from the flow of water inside the domestic pipeline.the shaft of the turbine rotates in unison with a series of magnets inside the generator. the large magnets rotate past copper coils which will produce eectricity. this electricity is then passed to the battery charge to be strored in a rechargeable battery. the pwer generated from the pipeline depends on the water flow rate,water consumption,pressure head and the turbine and generator used in this project. it is found that hydro power generation from the domestic ppipeline is able to reduce the use of electricity in household.
