As general contractor for the Cape Fear Public Utility Authority, Garney is installing 14 miles of 54″ welded steel raw transmission main to secure a reliable raw water source for the growing region of Southeastern North Carolina. The new waterline parallels an existing 48” PCCP line constructed in the 1980s and is being built to meet the growing coastal region’s demand for water. The project also includes three 66″ road bores totaling 695 feet, a 300-foot 66″ railroad bore, a 140-foot section of 54″ aerial water main across Livingston Creek, and four 48″ water service connections to the Brunswick County master meter.

The pipeline, manufactured by Northwest Pipe, traverses three counties and is one of the longest and largest water transmission mains in the region. The pipeline will transfer raw water from the Kings Bluff Raw Water Pump Station along the Cape Fear River in Bladen County to the Lower Cape Fear Water and Sewer Authority’s 3 MG storage tank in Brunswick County. The pipeline adds to a larger raw water system feeding the Sweeney Water Treatment Plant in New Hanover County and serves the City of Wilmington and the entire Southeastern coastline of the state.
