Additional work needed to complete water main break repair; no impact on water quality

“GLWA Field Service Crews and contractors continue to work around the clock to accomplish the repair of the 48-inch water transmission main that broke in the area of 14 Mile and Drake on Sunday, October 31. While crews had been successful in isolating the valves on the broken pipe to begin repair work yesterday, the isolation did not hold and water once again began filling the excavated area. GLWA has developed a solution to this issue that is planned to be implemented by Sunday, November 7, allowing crews to then complete the overall repair of the 20-foot section of water main by late next week. This timeframe includes pressure testing, disinfecting and flushing the main, as well as conducting water quality testing required after all repairs of this nature.

Throughout this process, impacted communities will continue to have water flow. However, it will continue to be at the lower level they have been experiencing since the main broke.

It should also be noted that the results for both rounds of water quality testing came back clear and the boil water advisories have been lifted in Commerce Township, Novi and Walled Lake.

GLWA will conduct a full analysis to determine the cause and any further assessments needed once all work is complete.”

GLWA Statement: Detroit Storage Partial Land Collapse & Possible Impact on Raw Water Intake(s)

December 6, 2019

The Great Lakes Water Authority (GLWA) is committed to ensuring that it provides its member partner communities in southeast Michigan with water of unquestionable quality. The Authority not only meets, but surpasses all standards related to federal and state Safe Drinking Water Act regulations.

GLWA has two raw water intakes in the Detroit River. One is located several miles upstream of the Detroit Storage site, a portion of which last week partially collapsed into the river. Because it is upstream of the site, there is no danger of any potential water quality issues from the collapse. The second intake is several miles downstream of the Detroit Storage site. However, the intake is located on the Canadian side of the Detroit River, and is not in the direct flow stream of the river where the land collapsed. Because of this, GLWA does not believe that there is any danger of this incident impacting water quality.

GLWA is in the process of conducting testing with an independent, third party laboratory for radionuclides and is requesting an expedited turnaround on these results.  The Authority will share these results as soon as they are available. This same testing was conducted in 2014 and no issues were identified.
