Cured-in-place pipe (CIPP) technology has improved reliability and reduced leakage in a project in California, US.
The pipeline runs along the Coral Cay/Seawatch fire access road between the Crystal Cove and Pacific Ridge communities in Newport Coast and delivers outdoor water used for irrigation.
Works began with pipeline cleaning and the removal of debris, roots and other materials that would prevent the proper installation of the liner, followed by a thorough condition assessment.
To minimise construction impacts, a standalone structural CIPP liner was installed inside the existing pipe using three access pits, extending the entire length of the original pipe.
After this, robotic reinstatement of service connection took place from within the pipe.
Liner installation began in late July, with pressure testing and repairs to damaged sections of the pipe taking place between September and November.
