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 Sunday, August 28, GLWA received delivery on the 16-foot segment that was sent back to the manufacturer because it did not meet GLWA’s specifications. The remaining 32-feet of pipe will be delivered in two shipments. One shipment is due to arrive on-site today, and the final piece will be put in-transit by this afternoon with an anticipated arrival within the next two days.


Crews are ready to begin repairs upon delivery of all 120-inch pipe to the repair site.


“Given the delays in receiving all required segments of pipe, I can confirm that GLWA will not be able to meet the original completion date of September 3, 2022,” said Suzanne R. Coffey, Chief Executive Officer, GLWA. “As soon as all the pipe is received on-site our crews will reassess the timeline and provide an update on the completion of repairs, including the steps we need to place the transmission main back into service. I want to thank our member partners and the residents of those communities that have limited their outdoor water usage. It has certainly assisted us in maintaining stable system pressures and operations.”


GLWA will share more information as it becomes available and plans to share photos with the media upon delivery of the remainder of the additional pipe.
