Kings Bluff 54-inch Parallel Raw Water Main

The Kings Bluff 54-inch parallel raw water transmission main provides a vital link in delivering a safe, dependable drinking water supply to approximately 500,000 residents in the growing communities of Brunswick County, New Hanover County, and Pender County in southeastern North Carolina.

The Kings Bluff system was challenged for several years by limited capacity and an aging 48-inch raw water main. This water main was constructed in the 1980s and was the sole pipeline responsible for delivering raw water to over 500,000 residents in three counties in southeastern North Carolina. The pipeline’s age and material resulted in multiple leaks, requiring costly and extensive repairs. Additionally, as a single point of failure in the water supply chain, the water supply to residents was severely impacted by the failures.

After a critical failure following Hurricane Matthew in 2016, a new raw water main was crucial to meeting future demands and delivering a continuous raw water supply.

McKim & Creed provided technical engineering services for the design, permitting, construction and post-construction phases of a new 54-inch parallel raw water main. The new pipeline, operating in parallel with an existing 40-year-old raw water main, increased capacity from 45mgd to 106mgd.

The design and construction of the new 54-inch water main were unique. This large-diameter pipeline spanned 14 miles through three separate counties and multiple regulatory jurisdictions.

The McKim & Creed team partnered with Brunswick County, Cape Fear Public Utility Authority (CFPUA), and Lower Cape Fear Water and Sewer Authority (LCFWSA) — each of which are customers and contributed to funding the project — to develop and deliver a successful project ahead of schedule and under budget.
