UPDATE 21

120-INCH WATER TRANSMISSION MAIN BREAK 

  • 120-inch water transmission main returned to service; regional system restored to normal operations
  • All requests for limited outdoor water usage lifted
  • Final incident report due to EGLE in 30 days 

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.

This past weekend GLWA returned its 120-inch water transmission main back to service and the regional system back to normal operations. This was several days ahead of the previously stated timeline of October 5. With normal operations restored, GLWA is lifting the request that the 23 originally impacted communities limit outdoor water usage.

“On behalf of everyone at GLWA, I want to express my gratitude to our member partner communities and their residents for their collaboration and support as we worked through the complexities of the break on what is the largest pipe in our regional system,” said Suzanne R. Coffey, GLWA Chief Executive Officer. “Although we encountered a number of obstacles along the way, I am so proud of how everyone involved dug-in and used their knowledge, skills and ingenuity to ensure that we made the repair as quickly as possible and kept our focus on protecting the public health.”

A final incident report is due to the Michigan Department of Environment, Great Lakes and Energy (EGLE) within 30 days. GLWA will post the completed report on its website, once it is submitted to EGLE.

    UPDATE 18
    120-INCH WATER TRANSMISSION MAIN BREAK
    • Transmission main is fully closed
    • Lake Huron Water Treatment Plant begins producing water to fill the 120-inch transmission main; 81 million gallons necessary to fill the 26 miles of main

    • Due to the size and length of the transmission main, GLWA estimates a return to normal operations within 15 days (September 21)

    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.

    With the 120-inch transmission main now fully closed, GLWA’s Lake Huron Water Treatment Facility has begun producing the 81 million gallons of water it will take to fill the 26 miles of main. Once the transmission main is filled, GLWA will work with the Michigan Department of Environment, Great Lakes, and Energy (EGLE) to implement a flushing and disinfection plan. Due to the size and length of the transmission main, GLWA expects this flushing and disinfection to take some time and is estimating a return to normal operations within 15 days (September 21).

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