Livingston, Alabama, located in mid-western Alabama, is home to the University of West Alabama (UWA). This project involved the replacement of existing water mains running parallel to Highway 11, bordering the UWA campus. Interestingly, water has a historical importance to the City of Livingston. In the latter part of the nineteenth century, Livingston became widely known as a health spa because of the water from its Bored Well. This well was bored by an old blind mule which pulled an auger around until an artesian aquifer was reached in 1857.
Goodwyn, Mills & Cawood, Inc. designed a replacement of the existing 6" water line with a new 8" DR18 DIPS PVC water main. Due to alignment requirements, a significant portion of the water main paralleled busy Highway 11 and the perimeter of the UWA campus. Horizontal directional drilling (HDD) was the specified installation method for 3,200 LF of the new water main. "Trenchless construction - horizontal directional drilling - offered the benefits of minimal surface restoration and disruption in the busy University community," commented Josh Peirce, P.E., Project Engineer.

The General Contractor, Goldman Contractors, selected Pinpoint Locating, Inc. to provide the HDD subcontractor services for the project. At completion of the project, Neil Goldman, Project Manager, said, "This is the second project that we have completed with Fusible PVC® pipe and we have been very pleased with the constructability benefits." Neil added, "Not having to upsize the pipe was a definite benefit of Fusible PVC® pipe for this project."
