An explosion-proof UV/VIS sensor has been available even in sewer systems for some years for simultaneous measurement of CODeq, filtered CODeq, TSSeq and nitrateeq. This sensor allows in-situ real-time measurements with no sampling, no sample preparation and no reagents. Three case studies are presented in this paper using this UV/VIS sensor for long-term sewer monitoring issues whereby two different installation strategies are applied. The pros and cons of both different installation solutions are compared and different calibration results during dry and wet weather conditions and long-term operational sewer monitoring experiences are given in this paper.
