Infrared Thermography for Sewer Inspections

Infrared Thermography for Sewer Inspections
Many of Europe’s sewer systems are now causing problems to due to there old age and under-capacity, many of Europe’s older cities was designed for populations many times smaller than present day.

Much of the water in a typical sewer is, in fact, ground water which enters through cracks in the sewer casing & joints etc. The water entering the sewer in this manner is usually at a lower temperature than the organically decomposing sewage, thus enabling infrared thermography survey to locate the sources of ground water ingress - and consequently the location of the cracks and misalignment of the pipes due to subsidence.
