UPDATE 19

120-INCH WATER TRANSMISSION MAIN BREAK

 

  • Flushing and disinfection process of the 120-inch water transmission main is ongoing
  • Due to the size and length of the pipe, the amount of water and the technical nature of the work, the process is taking longer than anticipated
  • GLWA now estimates a return to normal operations will take 6-16 days longer than originally thought (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.

While the flushing and disinfection of the 120-inch transmission main has been ongoing, due to the size and length of the pipe, as well as the technical nature of the process, GLWA is now expecting that it will take an additional six to 16 days to return the main to normal operations (October 5).

“We want to thank everyone for their patience as we navigate this situation together,” said Suzanne R. Coffey, P.E., Chief Executive Officer, GLWA. “We know that extending the timeframe to return the transmission system back normal operations will further inconvenience all of the communities and their residents, but it is necessary for us to ensure that we complete this repair in a way that safeguards the public health and the system.”

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

Industrial Waste Control

The Great Lakes Water Authority’s Industrial Waste Control group implements and enforces an Industrial Pretreatment Program (IPP) to regulate the discharge of commercial and industrial waste and wastewater. The IPP includes the following elements:

Pretreatment Program – regulates the discharge of toxic pollutants to the sewer collection system and performs inspection, monitoring, enforcement control and administration of industrial and commercial wastewater discharges. All Users must comply with general requirements and Significant Industrial Users must comply with permit-based requirements.

Surcharge (High Strength) Program – is a cost recovery program for commercial and industrial waste discharging conventional pollutants above Domestic Levels and payment of additional treatment costs ($/lb) associated with these Users.

Special Discharge and General Permit Program – authorizes the discharge of special wastes and wastewaters including groundwater, construction water, spent products, and other short-term projects through a permit program.

Hauled in Waste Program – authorizes the discharge from waste haulers of septic tank and septage, and other domestic wastewater through a permit and ticket/token payment program
