The Dare County Water Department has announced that construction to replace the water line that is located between the villages of Avon and Buxton on Hatteras Island has been completed.
On November 1, crews began to replace approximately 1.5 miles of the existing water line that runs along N.C. 12 in the Haulover/Canadian Hole area with brand-new, stronger C900 PVC piping.
The project — which was originally expected to be completed on April 1, 2023 — was finished ahead of schedule, with the new line being placed into service on December 12.
From November 2018 to September 2022, the existing 12-inch PVC Avon-Buxton water line experienced 10 ruptures.
Not long after the ruptures began, the Dare County Water Department began recording the pressure on the water line and determined that the highest pressure spike on the line was 80 pounds per square inch. The new water main can withstand 200 psi.
The Avon-Buxton water line replacement project was performed by Basnight Construction, Inc., at a cost of approximately $1 million.
