Abstract: Located along the southeast coast of South Carolina, Beaufort County’s population is rapidly expanding and that expansion brings new challenges to the county’s wastewater systems. To remain ahead of demand, the Beaufort Jasper Water and Sewer Authority (BJWSA) completed a pair of piping projects, including a new force main and reclaimed effluent line, relying on horizontal directional drilling (HDD) methodology and a focused procurement method commensurate with the installation risk. BJWSA worked with the same drilling contractor, engineering consultant, and pipe supplier for these installations as were involved in the first high-risk HDD project BJWSA completed in 2007.

First, a new, 5,300-foot, 16-inch force main was installed, using HDD, parallel to a similarly installed 10-inch pipe ten years earlier below the Beaufort River. This new force main was designed to augment flows to the Port Royal Island Water Reclamation Plant and additional wastewater collection capacity for residents.

Second, a new, 4,200-foot, 24-inch reclaimed effluent pipline was installed using HDD for the Great Swamp Expansion project. This new pipeline would allow even disbursement of effluent throughout the Great Swamp wetland area, returning cleaned effluent water to the local ecosystem for natural filtration and reintegration.

Ten years after the first long, historical Beaufort River HDD crossing, the success and efficiency of a procurement method that couples quality partnerships with material and performance capability prove repeatable of successive, higher risk HDD installations.
