The Jefferson Canal is both a cultural feature and an integral part of the community in New Iberia, Louisiana. In order to provide an efficient and controlled flow of water through the canal, the Iberia Parish Government determined that a unique control structure was needed.
Working with Royal Engineering, the Parish put together a set of plans and opened them to the public for bid which was ultimately won by Southern Constructors.
Working closely with Contech Engineered Solutions, Southern Constructors was able to provide the most optimal solution utilizing a CORLIX® corrugated aluminum pipe structure with a prefabricated aluminum headwall and factory attached flap gates to control flow through the canal. An aluminum solution was especially ideal in this situation as not only was it lightweight and easier to install, but it would also be able to withstand the brackish seawater of the canal.
Southern Constructors constructed earthen dams along the canal with a temporary bypass channel in order to open up the canal for the installation of the structure. The project consisted of five 20 LF, 84-inch diameter CORLIX® structures, flap gates, and aluminum headwalls and wingwalls manufactured by Contech.
Once the system was delivered to the site, the 20 LF CORLIX® segments with prefabricated headwalls already bolted on were easily set in place with light construction equipment. When complete, the structure was then backfilled, and a riprap revetment system was installed. The Parish was extremely pleased with the total project cost and ease of installation which resulted in a solution that met the structural and service life requirements and timeline that had been outlined. Zach Romaine, P.E., Engineer of Record from Royal Engineering, commented, "The project went very smoothly from our standpoint. The flap gates were easy to adjust as well." Ultimately, this improvement project will help to decrease upstream flow of tidal waters in the Jefferson Canal.
