OMID Sewer Rehabilitation: Innovative Slip Lining of a Large Diameter Sewer without Interrupting Service
This paper provides a case history and lessons learned from Segment 3 of the $180 million rehabilitation of the 12.75-foot diameter Oakland-Macomb Interceptor Drain (OMID) in Oakland and Macomb Counties, Michigan. The over 100-foot deep tunnel extends below 480 KV overhead power lines and several major roads. The sewer is non-redundant, and cannot be diverted. Multiple catastrophic tunnel failures have occurred since the 1970s construction. This project was undertaken to slip-line and structurally replace approximately 26,000 ft of the interceptor, protecting from future failure, without interrupting service to over 830,000 upstream users. This precedent-setting repair was conducted using an in-line flow storage system that involved holding flow behind in-line control gates daily, and slip-lining with centrifugally cast fiberglass reinforced polymer mortar (CCFRPM) pipe over 12 h shifts. All equipment was removed from the pipe daily and flow released during the night. Major innovations and successes included daily control of 100 million gallons of sewage while simultaneously installing 8 to 10-foot diameter slip-line pipe; development of a unique in-tunnel pipe delivery system; construction of shafts with low overhead clearance; and reduction of groundwater infiltration by 90 percent, saving millions in treatment costs each year.
