Sargent employee-owners are undertaking a $3.5 million sewer replacement project at the Loring Commerce Center in Limestone, replacing 10,000 feet of aging pipe and 40 manholes to prevent wastewater overflows into the Aroostook River watershed. The work involves deep trenching and upgrading old clay and brick infrastructure to modern PVC and concrete systems, with challenging groundwater conditions requiring careful environmental management. Crews are coordinating closely with regulators and working around active businesses to minimize disruption. The project, which carries historical significance for Sargent, is expected to span up to 350 days, with winter weather likely to pause progress.
