Fusible PVC® pipe used for HDD crossing of the Halifax River

An estimated 71,300 people live over 90 square miles in Daytona Beach, located in eastern Volusia County, Florida. All of the sanitary sewer flow from the city’s beachside service area flows through an existing 24-inch subaqueous force main, crossing the Halifax River to the city’s Bethune Point wastewater treatment facility. In 2016, a capacity analysis report recommended replacing the aging force main to provide significantly more flow capacity and improved reliability.

The city hired McKim & Creed, Inc. to design the replacement force main. Initially, five different alignments, each involving the installation of a 30-inch force main using horizontal directional drilling (HDD), were considered for the Halifax River crossing.
