BACKGROUND
The Great Lakes Water Authority operates nine combined sewer overflow (CSO) facilities. These facilities play a critical role in GLWA compliance with its NPDES permit requirements for adequate treatment from CSO outfalls and for protection of the system.

To manage this relationship between facility water level and river water level, a series of gates or valves exists to hold the river back during dry weather and allow CSO discharge into the river during wet weather. It is important when levels in the CSO facilities are higher than the river during wet weather for these gates/valves to be opened to allow relief of the collection system and to avoid potential basement backups.
