OCSD needed to safely and effectively divert sewage flow from a 30-inch diameter sewer line to the 66-inch Main Street trunk located 10 feet below. To avoid odors and additional expense, OCSD implemented the Vortex Flow Insert from IPEX USA LLC (www.ipexamerica.com), a leading supplier of thermoplastic piping systems. With no moving parts and requiring virtually no maintenance, the Vortex Flow Insert is a revolutionary technology for eliminating odors and minimizing corrosion in sewer drops.
