3D EAU: Expert Hydraulic Engineering Solutions

A decade-long provider of trusted sanitation and drinking water solutions
Founded in 2014, 3D EAU is a hydraulic engineering firm specializing in sewerage systems, drinking water, river management and industrial systems.
Our approach combines scientific precision with practical experience to develop robust, cost-effective, and environmentally friendly solutions for our clients.
We work closely with tem to ensure the safe and efficient operation of their projects, delivering high-quality, tailored technical support every step of the way.
The company originated from the ICube research laboratory at the University of Strasbourg.
Our expertise :
Designing measurement systems customized to the hydraulic configuration and specific needs of your facilities.
Validating the design of your existing or new hydraulic structures before construction to ensure proper operation and optimize construction costs.
Determining the optimal measurement points in the network and the best method for assessing transit flows, with the goal of gaining a deeper understanding of how the sewer network operates.
Our hydraulic equipment, tailored to your needs and manufactured in our workshops in France, to reduce your spills, minimise deposits and ensure reliable self-monitoring of spill flows.
Why work with us ?
International experience serving complex hydraulic projects
For more than 10 years, we have supported projects across Europe in the fields of municipal infrastructure, industrial applications, and water management facilities. Our expertise is grounded in international practice and reinforced by advanced simulation capabilities.
Specialized in wastewater, drinking water, and industrial hydraulic systems
Whether sewer networks, retention basins, drinking water pipelines, or industrial processes involving fluids – we analyze, validate, and optimize every type of hydraulic system. Our focus is on reliable operation, regulatory compliance, and the cost-effectiveness of your solution.
Tailored solutions with long-term technical support
Every project is unique – that’s why we develop customized solutions tailored to your facilities and objectives. Even after project completion, we remain your technical partner: for adjustments, monitoring, further developments, or new challenges.
Our hydraulic modeling services
Innovative solutions and expertise

In the design phase, to validate and optimize a planned structure
In the diagnostic phase, to assess and adapt an existing structure


We offer various hydraulic modeling solutions :
- 0D, 1D, and 3D modeling tailored to the specific context of each project

- In the instrumentation phase, to assess the number, placement, and type of sensors needed to ensure optimal measurement precision.
Computational fluid dynamics (CFD) : an innovative speciality

Initially used in the aerospace sector, 3D EAU has set itself apart by harnessing the power of 3D modeling in hydraulics, revolutionizing the design and instrumentation of hydraulic structures.
Using a combination of advanced techniques and established methods, 3D EAU’s 3D hydraulic modeling delivers a range of benefits for your projects:
- Enhanced precision and quality
- Reduced design and execution time
- Seamless integration of hydraulic and control systems to optimize performance
Our project management methodology :
1
Identifying your needs and offering a tailored solution
2
Setting up a project team, followed by a steering committee meeting to coordinate the various parties involved in the project
3
Conducting an on-site inspection and survey of the structure
4
Carrying out the study
5
Holding a final feedback meeting to present the developed solution
6
Facilitating the implementation of the proposed solution
Our values
Independence, guaranteeing total objectivity for our customers: no external financial contribution (in particular, no shareholding in the company), no exclusivity contracts.
Innovation: thanks to our close collaboration with the ICube research laboratory, from which the founders of 3D EAU originate, we are able to offer you innovative solutions at the cutting edge of the latest technological advances.
Respect for the environment is a priority for us. As well as promoting public transport and sustainable and responsible purchasing, we are also committed to limiting pollution and optimising our treatment processes.
