In 2020, the City Commission of Ft. Lauderdale, Florida approved a $65 million fund for the design and construction of a 7.5-mile–long pipe that will serve as a redundant wastewater transmission line. The extended line would start from Coral Ridge Country Club Wastewater Lift Station and end at the G. T. Lohmeyer Wastewater Treatment Plant (GTL), providing improved infrastructure with redundancy, enhanced reliability, and improved services.
One challenge with the project was that some sections of the 7.5-mile-long pipe extension runs near or along streets and roadways as well as residential zones and neighborhoods. To help minimize the impact in these areas, a piping material that was capable of being installed using underground horizontal directional drilling (HDD) was required.
To overcome installation constraints, engineers chose to use high-density polyethylene (HDPE) sewer pipes. In addition to being flexible and durable enough to support HDD, HDPE pipes are more resistant to corrosion and have fewer mechanical joints, which together help reduce long-term maintenance requirements. The piping system is also expected to improve the infrastructure’s resilience to rising sea level and groundwater table.
Two contractors, Murphy Pipeline Contractors and David Mancini & Sons, worked simultaneously to fast-track construction, with the northern portion handled by Murphy Pipeline and the southern portion handled by David Mancini & Sons.
The new force main was completed without issue and set a record for one of the longest and largest HDD pressurized sewer pipe installations in the world, at 3,100 ft at OD 54. The installation required fusing about 23 sections of pipe as it was being pulled underground.
