One mark of a successful project is when a client chooses to repeat it. In South Carolina, two separate 10-inch and 16-inch Fusible PVC® pipe projects, paralleling one another over roughly a mile long stretch, have both been installed using horizontal directional drilling (HDD) method over ten years apart.
In 2007, the first, a 10-inch diameter Fusible PVC® pipe located in South Carolina that measured a mile long, was installed using HDD by Underground Solutions and Beaufort Jasper Water & Sanitation Authority (BJWSA). At the time, it tripled the longest length of Fusible PVC® pipe that had ever been installed using the method. The installation required a focused attention to detail, a high-quality pipe product and a great contractor and end user team. The project was a landmark success and that pipe is still in service today.
Ten years later in 2017, BJWSA needed to parallel the 2007 installation with a 16-inch force main to augment flows to the Port Royal Island Water Reclamation plant. This required another long HDD crossing of the Beaufort River. BJWSA assembled the same team that generated success 10 years ago. Underground Solutions supplied Fusible PVC® pipe and fusion services and Hussey, Gay Bell and DeYoung designed the pipeline while Mears Group performed the horizontal directional drilling and pipeline installation.
After completion and preparation of the borehole, insertion of the Fusible PVC® pipe began on Thursday, March 8, 2018 and continued for 16 hours, with pipe reemerging approximately a mile away from the insertion location in the early morning on March 9. At completion, 118 joints were fused on the project, including 5 intermediate fusion joints during the 16 hours of pullback.
