IPR Southeast Introduces Cured In Place Pipe Technology in Altama Avenue
Brunswick-Glynn County Joint and Water Sewer Commission (BGCJWSC) was undergoing a rehabilitation project of a 4,300 linear feet, clay pipeline system, prioritizing the worst sections first. Although they were set to repair the Sea Palms neighborhood first, their contractor IPR Southeast, an Inland Pipe Rehabilitation subsidiary, took a detour to a different section of the pipeline. Altama Avenue was prioritized for rehabilitation due to its condition and the potential hazard to the underground infrastructure.
"While not the highest on the list, Altama Avenue has been a priority area for the JWSC for some time," said administration director Jay Sellers. "We have one where debris is stuck in the pipe, meaning illegal dumping. Concrete."

Traditional trench repair methods would require to tear up the asphalt, remove the wide grass median and delay the busy thoroughfare. However, IPR Southeast is proficient with the trenchless technology called Cured In Place Pipe (CIPP). The Cured In Place Pipe lining system is the most proven trenchless pipeline rehabilitation process. CIPP is a resin-saturated felt tube that is inverted and cured in a deteriorated pipe. Rather than digging up the road, CIPP requires only one entry point. It is a cost-effective way to extend the design life of water and sewer infrastructure without decreasing capacity. "It's like a sock," said Ulysses Franklin, a superintendent with IPR. "We turn it inside out in the pipe."
At the installation site, the liner is attached to the shooter and inverted into a manhole using air or water pressure. Once the liner is fully inverted, the curing process begins by circulating hot water or steam into the liner. The heat from the curing process activates the resins and hardens the liner creating a new pipe within the host and extending the design life by 50 years. The services are then reinstated using robotically operated cutting equipment.
After the rehabilitation of Altama Avenue, IPR Southeast and BGCJWSC plan to return to Sea Palms to finish the project by the end of August 2020. IPR's iconic green steam struck will move throughout each section of the pipeline about once a day. The project is expected to wrap by September 2020.
“All of the folks at Brunswick-Glynn County have been great to work for and we’re proud to provide them with a lasting solution to their aging infrastructure. Being able to rehabilitate a severely deteriorated pipe that is over 70 years old and lying beneath a major 4 lane road in a day’s time with no surface disruption is exactly why municipalities come to us for help.”
