Construction continues for the consolidation sewer pipe that will transport flow from neighborhoods north of the St. Marys River to a drop shaft and ultimately to the deep rock tunnel. Currently, overflows from these rivers dump into the St. Marys River at Third Street. This outfall is the largest outfall in the sewer system.
In the photos below, you can see the work that is going on below the bottom of the riverbed. The steel sheeting is the cofferdam that holds the water. The gray whalers above the workers support the dam. The last picture, showing the men standing on the scaffolding, gives us perspective. Their feet are just below the riverbed level. If the cofferdam weren’t there, they would be underwater.
