Ponte Vedra, Florida

Many communities face the task of replacing septic tanks with a modern wastewater collection system. Ponte Vedra Beach, Florida, did it cost effectively and with minimal disruption.

Like many coastal areas, Ponte Vedra Beach has a high water table and sandy soil, conditions that make gravity sewer installation very difficult. In 2003 the Jacksonville Electric Authority (JEA), which serves Ponte Vedra Beach, needed a new sewer system to serve a 672-home subdivision. To install a gravity system would have required trenches 20 feet deep, extensive dewatering and years to complete.

To avoid these problems, the JEA elected to use vacuum sewer technology by AIRVAC and to do the project using the Design-Build method. The team of Eckler Engineering, Inc., and Callaway Construction, Inc., were awarded the contract to design and install the $10 million system. The project was completed in less than two years. The system has 45,000 feet of 6, 8 and 10-inch collection lines with an average trench depth of 4-6 feet.

“With gravity systems, you are at depths of 20 or more feet. That makes installation disruptive and time consuming,” explained Stan Bates, project manager for Callaway Contracting. “Vacuum technology made this job very easy, relatively speaking.”

As a result of this successful vacuum project, JEA is planning on using AIRVAC technology in other areas within their jurisdiction, with several other projects currently in the design phase.
