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.

Self-monitoring

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.

Consulting and engineering services for the development of innovative solutions in urban water and water cycle management.

3DEAU participates in the design, assessment and instrumentation of hydraulic structures in the water and environment sector. Design of complex hydraulic structures, self-monitoring of discharge and continuous assessment of your sewer systems.


Environmental protection is a key priority: Opting for an in-depth hydraulic study means environmental issues can be handled in a coherent manner. This approach also presents major advantages in terms of the robustness of the proposed solution and the investment and maintenance savings achieved.
3DEAU guides you throughout the process of designing a tailored solution that fits the local context and challenges. 


3DEAU thus offers you peace of mind and security in the daily management of your sanitary sewer systems, thanks to high-quality, customised support.

3D MODELLING: an innovative technique

Technqiue-3D.gif

3DEAU stands out for its use of 3D modelling for the design and instrumentation of hydraulic structures. 
Originally designed for the aeronautics industry, the technology used by 3DEAU is adapted to the context and constraints of hydraulic systems. 
3DEAU offers you a numerical alternative which, in conjunction with conventional technologies, enables us to guide you towards the solution that best meets your needs.


When 3D modelling is applied to the design and self-monitoring of structures, the special characteristics of each site can be taken into account, so that specifically calibrated retrofit adjustments can be devised. The modelling system is implemented by hydraulic specialists capable of anticipating the functioning of each structure and of setting up the simulations accordingly. 


3D modelling is a powerful analysis tool that is needed to understand complex hydraulic structures. This understanding is crucial to the development of solutions that are easy to implement and operate.
