Intelligent inspection: Rosenxt demonstrates new capabilities for PCCP assessment
In May 2025, three colleagues from Rosenxt visited the Zweckverband Bodensee-Wasserversorgung near Tuttlingen (Baden-Württemberg) to test a newly developed inspection technology on an original PCCP pipe segment (prestressed concrete cylinder pipe).
The objective was to detect artificially induced wire breaks in the prestressing wires—both with a handheld device for external inspection and a system designed for internal examination. Both technologies were deployed under realistic conditions, further developed, and successfully validated.
A particular highlight was the use of an inline inspection robot specifically designed for PCCP pipelines. The robot was calibrated on-site and demonstrated its capabilities impressively: even during active operation, it reliably and accurately detected wire breaks. PCCP pipes are large-diameter concrete pressure pipes used globally in water infrastructure systems to transport fresh and wastewater.
Representatives from Bodensee-Wasserversorgung were present to witness the technology’s potential firsthand.
Overall, the test measurements were a complete success. The collected data not only showed promising results but also provided valuable insights for the continued development of our inspection tools. This allows us to further optimize our technologies—with the clear goal of enhancing safety and efficiency in assessing the condition of PCCP pipelines and ensuring supply security.
We would like to sincerely thank the Zweckverband Bodensee-Wasserversorgung for providing access to their PCCP test pipes, which enabled us to validate our tools under realistic conditions.
