Water plants have many important functions that need to be run efficiently every time. When there is a power outage at the water plant, many functions will stop working and the plant operator will not be able to work properly. Diesel generators help run hydraulics, pumps, run fans, and other functions in a power plant. When a power outage occurs, the generators restore power within seconds so consumers can continue to use them wherever they are. These facilities also help keep the spillway's gates from flooding, especially when the grid goes out.
