Halzhausen 1500mm Trunk Main

Faced with severe leaks in a critical 1500mm trunk main, Radius Subterra provided an innovative pipeline rehabilitation solution using their close-fit PE liner system. This approach restored the pipeline’s integrity within tight time constraints, eliminating ongoing leakage issues and extending the pipeline's lifespan by 50 years.

Challenges Radius Subterra Faced

Significant Leakage: The main trunk supply pipeline was losing up to 35 litres per second due to the degradation of rubber sealing gaskets at many joints.

Limited Downtime: The pipeline, which forms a critical link between Geislingen and Langenau, could only be taken out of service for a maximum of three days, limiting the time available for repairs.

The Radius Subterra Solution

Innovative Liner System: Radius Subterra re-engineered and extended its folded close-fit PE liner system to rehabilitate the 2.3-kilometre-long, large-diameter water supply trunk main. This approach avoided the high costs and disruption of traditional relaying methods.

Rapid Insertion and Restoration: The careful preparation and rapid insertion of the liner allowed the pipeline to be restored in less than two days, maintaining bulk supply reserves and preventing critical service disruptions.

Conclusion

Radius Subterra successfully restored the pipeline’s capacity and functionality by implementing a close-fit liner solution, providing a continuous protective barrier with a lifespan of at least 50 years. The intervention eliminated ongoing leakage issues, removing the need for repetitive repairs and hazardous man-entry maintenance.
