UPDATE 20
120-INCH WATER TRANSMISSION MAIN BREAK
- Flushing and disinfection process of the 120-inch water transmission main is completed
- Three rounds of water quality testing completed; results confirm that the water meets or surpasses regulatory standards
- GLWA has now begun the process of returning the regional system to normal operations; this is expected to occur by October 5
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.
As repairs were being made, GLWA communicated that there were three phases to the repair process: 1) water main inspection and repair, 2) water main disinfection, flushing, and water quality testing; and 3) restoration of the water transmission main to normal operations.
With phases one and two completed, and water quality testing results confirming that the water meets or surpasses regulatory standards, GLWA has now begun the process of returning the 120-inch water transmission main to service, as well as the rest of the regional system to normal operations. While GLWA does not expect there to be any major impacts to the regional system during the restoration, some of the 23 originally impacted communities may see limited fluctuations in their water pressure throughout the next day or so.
GLWA expects this return to normal operations to occur by October 5.
More information will be shared as it becomes available.
