This presentation will cover the most common design and execution errors encountered in the technical rehabilitation of sewer pipelines. The errors will be discussed both from a general perspective and in relation to selected trenchless rehabilitation techniques commonly used in Poland, including continuous pipe lining, cured-in-place pipe (CIPP) lining, and modular pipe lining.
The presentation is aligned with the guidelines currently being developed by the Polish Society for Trenchless Technology (PSTB) for planning investments in trenchless rehabilitation of sewer and water networks.
