Abstract
The results of experimental and methodical works complex of geophysical methods in two sewer lines. One line has been previously surveyed by tele to develop criteria for identifying areas of geophysics pipeline emergency requiring major repairs. A comparative analysis of materials telephoto and geological and geophysical data suggested a criterion for allocation of emergency pipeline sections only on geophysical data (without telephoto). This technique has been used in the assessment of sewer pipe at the emergency site, where the tele was not possible. The results of the geophysical survey were confirmed during the overhaul.
