The Great Lakes Water Authority (GLWA) said the Lake Huron Water Treatment Facility has begun producing the 81 million gallons of water needed to fill the 26-mile main. Once it is filled, the Authority will work with the Michigan Department of Environment, Great Lakes, and Energy (EGLE) to implement a flushing and disinfection plan.
Normal main operations are expected to resume Sept. 21.
The main broke in mid-August. Repairs have taken so long because the break was worse than initially thought, and it required more pipe to be ordered.
