In order to propose a new sewer inspection method, a velocity/turbidity profiler (Ubertone, UB Flow) has been tested in a laboratory. A 50 m glass flume has been adapted with several lateral connections (with a arnge of diameter, angle, intrusions, cracks), supplied by a 1 m3 tan

Les réseaux d’assainissement séparatifs sont de plus en plus préférés aux réseaux unitaires mais ils sont sensibles aux erreurs (in)volontaires de branchements entre les bâtiments et le réseau. Il existe quelques techniques d’inspections spécifiques à ce type de recherche : les t

Separate sewers are more and more preferred over combined ones but are sensitive to misconnections. Several inspection techniques (time consuming and expensive) are specifically devoted to detecting such misconnections: smoking test and dye tracing are the most popular. This pape

Sewer inspections are usually done with CCTV. For a decade, emerging techniques have been developed and drones seem to offer new opportunities. The use of a velocity profiler is investigated in this study in order to identify and quantify velocities distributions created by later
