Trash Rack
A Trash Rack is a protective barrier installed at hydroelectric power plants to prevent debris, logs, and other floating materials from entering and damaging the power generation equipment. Think of it like a giant protective screen or filter that keeps unwanted materials out while letting water flow through. This equipment is crucial for maintaining the safety and efficiency of hydroelectric facilities. Other names for this structure include 'debris screen,' 'intake screen,' or 'water screen.' Understanding this term is important because it appears frequently in maintenance, engineering, and operations roles at hydropower facilities.
