The town of Palm Beach, FL, is located on a long, narrow barrier island 65 miles north of Miami and is well known for its many multimillion-dollar mansions. The expensive real estate and the ever-present saltwater are major complications for the Public Works Department; saltwater corrodes everything, and digging things up for repair is always costly. Therefore, maintenance and trenchless methods are high priorities, and the department is always alert for new technologies.
To dewater the system, Depicciotto devised a system of two temporary barrier walls and pumps that let him work at low tide. After using scraping and high-pressure washing to remove oysters and other buildup, he was ready to apply COR+ROC with Centri-Pipe. “The pipe actually looked pretty good after cleaning,” says Depicciotto, “which was good, of course; it meant we didn’t have to repair gaps before application and that we can stop corrosion before it happens. With the COR+ROC in place to protect against salt damage, this storm sewer should be trouble-free for decades.”
