South Walton Utility Company, Inc. (SWUCI) provides water and wastewater utility services to the Santa Rosa/Destin areas of the Florida Panhandle. Recently, SWUCI was faced with a challenging relocation project for a reclaim water line. The Florida Department of Transportation (FDOT) was planning to widen sections of US 98, which would encroach on an existing reclaim waterline. In order to prevent the existing reclaim waterline from being located under the new roadway, a section of the line needed to be relocated.
Under most circumstances, relocating a 500-foot water line would be a relatively simple task. In this case, however, SWUCI’s available space was confined by a very limited easement, commercial property conflicts, and an existing wastewater lift station. Not only was the lift station situated within the narrow, available easement, the bottom of the lift station was 14 feet below the surface. Based on these limitations, the only viable option was to “surgically” install the new waterline segment via horizontal directional drill (HDD) to travel under the existing lift station while staying within the limited right-of-way.
|Pipeline Details and Project Summary|
|Project:||Geronimo Street Reclaim Water Relocation|
|Location:||Miramar Beach, FL|
|Pipe Size:||12” DR18 DIPS Purple|
|Pressure Test:||150 psi|
|Installation:||Horizontal Directional Drill|
|Owner:||South Walton Utility Company, Inc.|
|Engineer:||South Walton Utility Company, Inc.|
|General Contractor:||GAC Contractors|
|HDD Contractor:||Gator Boring and Trenching, Inc.|
SWUCI Project Manager, Alicia Keeter, said: “We specified Fusible PVC® pipe for this relocation project to maintain pipe material consistency, hydraulic capacity, and fittings compatibility. No special fittings were required. Not having to upsize the pipe minimized the required borehole size and the associated risk with boring in the immediate vicinity of the existing lift station.”
Gator Boring and Trenching performed pipe fusion services and HDD installation for the project. Eric Lyons, Gator Boring’s owner, commented: “The pilot bore and reaming for this project were challenging because of the narrow alignment, sandy soils, and proximity to the existing lift station. Once we had the borehole properly prepared, the installation of the Fusible PVC® pipe was successfully completed within several hours.”
Fusible PVC® pipe and the improving accuracy of trenchless construction methods combined to provide an economical solution for this challenging utility relocation project.
