Training objectives
- Gain a hydraulic understanding of a flow measurement point in a sewer network or wastewater treatment plant.
- Gain a physical understanding of the hydraulic operation of a measuring point in order to identify potential problem areas (steep slope, presence of a flap valve, risk of downstream influence, deformation of the measuring device, etc.).
- Identify and quantify the hydraulic characteristics needed to assess the hydraulic operation of a measuring point, and therefore the recommendations to be made.
3D EAU training
Flow measurement in wastewater systems
Program
Day 1 is aimed at a wide audience (field operatives, technicians, engineers, etc.) and will illustrate :
– measurement sites and issues through practical case studies: instructional videos filmed on a network or in a station (storm overflow weir, pumping station overflow with or without caisson, gauging channels, etc.).
– hydraulic phenomena at play (torrential flow, hydraulic overflow, downstream influence, control point, etc.) thanks to videos shot in the laboratory.
The 2nd day is aimed at technicians and engineers. In particular, they will see the implementation of field cases presented the day before, or examples directly proposed by the participants of this training course.
