What are Penstocks in Hydropower Plant?

Apart from being used in hydropower plants, it is also utilized for its functions in an irrigation dam or a mine tailing dam construction. Proper precautions should be taken when the sources of water are polluted in a hydroelectric system by cleaning the penstocks using hot water, manual methods or by coating it with an antifouling solution.
