Project Information

Design Engineering, Inc. (DEI) was contracted by the Coastal Protection and Restoration Authority (CPRA) to lead the Engineering Services for the Violet Siphon (PO-01) Intake Repair project. As an amendment to the original contract, we were tasked with performing a comprehensive visual and acoustic inspection of the exposed portions of the Violet Canal Siphon pipes and the discharge weir box structure.

The Violet Canal Siphon, located in Violet, Louisiana, is a critical component in conveying water between the Mississippi River and Violet Canal. Using cutting-edge technology, including the Inuktun VersaTrax 150 Crawler System and Imagenex Model 831 A Digital Pipe Profiling Sonar system, our team thoroughly inspected the interior and exterior of the pipes to ensure their structural integrity. The Violet Canal Siphon structure, a timber and chain-link fence structure supported by 70-foot long timber piles, was unfortunately struck by a marine vessel and was in need of removal and replacement.
