Sargent returned to Colby College in Waterville, Maine, in summer 2026 to replace and install new water lines as part of a campus-wide water infrastructure upgrade led by A/Z Corp. – A Cianbro Company. Sargent removed existing cast iron lines and installed approximately 850 linear feet of new pipe, navigating ledge and multiple utilities—including power, communications, steam, and water—buried within the same trenches. Work at two campus locations also included hoe-ramming approximately 90 cubic yards of ledge and installing fencing to maintain safety around active campus areas. The project began in May 2026 and was completed two months later.
