Elaboration of a method to measure the flow rate transiting through the junction gate of sewers VL9 and VL10 (SIAAP, 2014-2015)

Elaboration of a method to measure the flow rate transiting through the junction gate of sewers VL9 and VL10 (SIAAP, 2014-2015) The SIAAP (Greater Paris Sanitation Authority) has undertaken the junction of two primary sewers, VL9 and VL10, which are both very deep and difficult to access. The objective of this study, assigned to SAFEGE and 3D Eau, was to develop a flow rate measuring device using the existing sensors in place and avoiding adding new sensors, by: modeling the junction and the upstream shaft in 3D developing a new flow rate law taking into account the fluid storage in the network.
