Innovative solutions by 3D EAU
Implementation of site-specific measurement solutions
The continuous monitoring of flow rates at specific points in the sewer system allows for the collection of real-time data on the condition and operation of the network, enabling rapid identification of potential issues and assessment of the effectiveness of corrective actions.
The methodology outlined aims to understand and caracterize the hydraulic flow and environmental constraints in order to select the most optimal measurement solution based on the key considerations and objectives.
Definition of the measurement equipment to be installed
Flow measurement at characteristic points in the network makes it possible to analyse dry weather and wet weather flows, identify continuous infiltration of clean water in the system and validate hydraulic models. However, it is complex to implement, as the collectors are not designed for this type of measurement.
Hydraulic assessment of sectorisation points
Do you want to implement or improve the reliability of your measurement point instrumentation? 3D EAU offers hydraulic expertise for each site, so you can choose the continuous flow measurement solution best suited to the context and the issues at stake.
1. Field surveys
2. Plan for the upcoming measurement campaign
3. Rainfall data analysis
4. Flow data analysis
Comparative analysis of measurement solutions
Several measurement solutions are considered, such as the installation of a calibrated venturi-type device in the network, implementation of the H2Q method, choice of a speed probe, etc.
They are then discussed in the light of various criteria (measurement accuracy, investment cost, operating cost, impact on the hydraulic operation of the network, etc.).
5. Comparative analysis
Drawing up the measurement solution chosen for the sectorisation point
Once the solution has been chosen by the client from among the proposed solutions, 3D EAU will draw up the procedure for calculating the flow rate and the associated uncertainties.
