Abstract
Pollution fiows on receiving waters measurement is now compulsory in France to survey the sewer systems functionning but metrological problems still remain. Continuous pollution measurement systems (based on turbidity and ultra-violet and visible absorbances) were tested in situ (in a combined system at the upstream of a detention basin). These systems require still precautions (hydraulic feeding line, maintenances, calibrations...) Neverheless we can be optimist in regards to the results which have been obtained: the optical measurement of SS and COD is interesting to determine average or long term pollution loads.
