Recently, the river-crossing pipe repair project of the external pipeline network of Shantou South Area Sewage Treatment Plant was successfully completed, and the water supply operation was fully restored. The project innovatively added fiberglass to the repair materials to enhance toughness, successfully achieving China's first one-time cured-in-place pipe (CIPP) lining repair for a 550-meter ultra-long sewage pipe. This feat has given new life to this "underwater lifeline", marking a major breakthrough for Shantou in safeguarding critical infrastructure and protecting the aquatic environment under complex conditions.

This achievement fills a domestic technological gap and contributes a replicable "Shantou experience" for the repair and maintenance of projects in sensitive areas such as crossing rivers. Currently, the project's construction contractor is actively applying for the "Science and Technology Award of the China Urban Water Association".
