Hayward Baker works on award-winning public works project
15 Mile Sewer Repair project was recognized with multiple awards following successful year-long recovery in the wake of a sewer collapse in Macomb County, Michigan.
The Romeo Arm Interceptor is an 11-feet-diameter wastewater pipeline part of the Macomb Interceptor Drain Drainage District in Macomb County, Michigan, serving approximately a half million residents, 40,000 businesses, 11 communities, and the Selfridge Air National Guard Base.
A sinkhole developed along 15 Mile Road between Hayes Road and Moravian Drive on December 24, 2016 measuring approximately 100 feet wide by 200 feet long and 10 feet deep. Presumed to have resulted from ground loss caused by fines infiltrating the sewer through cracks or joints in the pipe, the sinkhole continued to expand with the potential to become an environmental disaster.
Disposable personal wipes were discovered to have exacerbated the problem. Even though they are flushable, they are not biodegradable and therefore choke sewage pumps, blocking flow.
Hayward Baker performed compaction grouting to densify the loosened granular soils on either side of the sewer and stabilize ground lost as a result of the sewer collapse. Responding under emergency status, Hayward Baker crews completed this work in about a month.
“I cannot help but think of the… thoughtful and professional manner in which the way all of you went about your jobs to get that job done in a way that protected our environment and our quality of life,” Macomb County Public Works Commissioner Candice Miller says of the project partners. “I was and remain incredibly proud to have you on our team.”
Wastewater flow was restored to the successfully repaired interceptor in September 2017 after an intensive, year-long effort. The road was reopened to the public that December.
“HBI field personnel and equipment from multiple regions were mobilized immediately to operate in frigid temperatures,” says Senior Project Manager Spring Borchardt. “I applaud everyone on the team for their efforts on this sinkhole recovery, including Superintendents Steve Rodriguez and Scott Bruno. I’d also like to acknowledge Field Engineer Carly Miller for assisting with managing the two crews from HBI-Denver and HBI-New York and maintaining the group’s focus.”
