Offering the best sewer inspection & inventory tool


Thanks to the SewerMapper, there is no need for a worker to go down the manhole anymore. This means dangers of falling, drowning and suffocation are almost nonexistent.


The SewerMapper can scan, parametrize and map a complete manhole and sewer up to 3 times faster than a manual inventory. Results are also more accurate and complete!


Using ESA’s expertise and satellites, the SewerMapper can precisely determine the location and orientation of a sewer. Every manhole can thus be linked to an entire 3D sewer network!


No more manual measurements and computer inputs! The SewerMapper is an exhaustive tool that only has to be placed above a manhole; measurements, parametrization & upload are easy-as-pie.
