Introduction to the tailrace

After passing through the hydraulic turbine, the water carried by the water flow can be absorbed and used by the hydraulic turbine and becomes the waste water. The channel that discharges waste water from the power plant building to the downstream river bed is called tailrace. When the factory building is underground, the tailrace and the factory building are often connected by a tailrace tunnel. If the tailrace tunnel is a non-pressurized tunnel, it also becomes a section of the tailrace.
