At present, sewerage networks for municipal and industrial wastewater are standardly built using single-skin pipes, even in environmentally or otherwise exposed localities with increased risk. As a rule, on-line inspection of the tightness of the pipe jacket on these sewer networks is not performed and required, and therefore the identification of the fault at the time of its occurrence is not ensured. In these areas with an increased risk, the possible contamination of soil and groundwater is not prevented, as well as the operative elimination of any defects that have not been ensured.

The goal of online monitoring carried out in the AdMaS center in cooperation with Satturn HoleSov and the Department of Telecommunications at the Faculty of Electrical Engineering and Communication is therefore the most detailed coverage of the sewer network for leak localization, while high measurement accuracy is not required. These assumptions predetermine the possibility of using “cheap sensors”, which do not necessarily accurately measure the measured quantities. It is sufficient if they can capture with sufficient accuracy the “changes” caused by the creation of a leak. Sophisticated applications using optical cable using Raman scattering in optical fiber also seem to be suitable.
