Design / assessment of structures

3DEAU validates the design of hydraulic structures prior to construction, in order to ensure proper functioning and to optimise construction costs. 
3DEAU also leverages its expertise to assess the functioning of existing hydraulic structures, with the aim of optimising them.

Due to regulatory self-monitoring requirements, combined sewer overflows have to be equipped with instrumentation, although they were not initially designed for this. 3D modelling offers the possibility of doing so without significantly altering their configuration.


In this way, the flow rate discharged to the receiving environment is evaluated in a way :

  • Precise: validation of the sensor’s location, numerical calibration of the head-discharge relationships and evaluation of the associated uncertainty.

  • Economical: little construction work is involved, and non-contact water level sensors are used.

  • Operational: the water level measurement is easy to check.

Permanent Diagnosis

Permanent diagnosis is essential to monitor and diagnose the operation of its sanitation networks on a daily basis with the help of measurement points. 

The expertise offered by 3D EAU in terms of hydraulic analysis makes it possible to judiciously position these measurement points in a network and to determine the measurement technique best suited to the issues at stake in order to evaluate the flows transited :

  • More precise: validation of the sensor location, numerical calibration of the height/flow laws and evaluation of the associated uncertainty.

  • More economical: little work and use of non-contact height sensors

  • More operational: the height measurement is easily controllable.
