This is an image of the up-river facility of Dissolved Oxygen Injection System, as part of the Savannah Harbor Expansion Project. This feature will remove water from the river, inject it with oxygen using devices called Speece cones, and return the water back to the river. These devices will maintain the level of dissolved oxygen in the harbor at the pre-SHEP 47’ deepening level. The image here shows the facility at about 30 percent complete.
