The development of monitoring system technology enables more accurate and at regular intervals measurement of many parameters affecting the safety and proper functioning of underground infrastructure. Means of monitoring underground infrastructure using distributed fiber optic sensors (DFOS) are presented in this paper. DFOS use is developing rapidly and investment is increasingly visible internationally – examples are given. The preliminary results are also presented of research on the application of DFOS for monitoring pipeline deformation and thin-walled GRP (FRP) panels used in the renovation of existing sewage networks.


  • modern method of monitoring collectors and pipelines.

  • Significant improvement of measurement resolution compared to traditional monitoring methods.

  • lower installation costs compared to traditional monitoring systems.

  • low maintenance costs of monitoring.

  • increasingly used in underground construction.
