Storm Sewer Collapse
Fairfield, AL

A big box store in Fairfield, AL was experiencing reoccurring sink holes in its parking lot, and CCE was hired to investigate whether the sink holes were caused by a failing 40-year-old underground storm sewer system.

After inspecting ¼ mile of underground storm sewer piping, CCE found that one of the dual 84” pipes was totally collapsed. With only one functioning pipe, the system was unable to handle overpowering flow that deteriorated the pipe walls and eroded the surrounding soil. To repair the storm sewer system and prevent future sink holes, CCE replaced 1,350 l.f. of the old dual pipe with a single 102” storm sewer pipe. CCE also prepared contracts and provided detailed phasing plans that enabled the store’s continued operations through construction.
