DETROIT – The Great Lakes Water Authority (GLWA) is providing an update on the August 13 break to the 120-inch water transmission main that distributes finished drinking water from its Lake Huron Water Treatment Facility to communities in the northern part of GLWA’s drinking water service area.

On Wednesday, August 31 crews completed the placement of all new segments of pipe at the site of the broken 120-inch transmission main just west of GLWA’s Lake Huron Water Treatment Facility. Today, crews are working to complete all the connections between pipes that are required to fully close the transmission main, as well as pour a concrete foundation underneath the new segments of pipe to provide it with long-term stabilization.

GLWA will share an updated timeline for returning the 120-inch transmission main back to service once the transmission main is fully closed.

GLWA will share more information as it becomes available, as well as photos of progress being made at the repair site.
