ABOUT
A human-scale consultancy, dedicated to the water cycle
EcoSync Engineering is an independent, human-scale engineering and advisory consultancy based in France.
We cover the entire water cycle: drinking water supply, wastewater systems, stormwater and urban drainage management, rivers and aquatic environments, treated water reuse and irrigation.
We deliver pragmatic studies and designs, ready for regulatory compliance: master plans, hydraulic modelling, options appraisals, infrastructure sizing and construction support. Our clients include local authorities and inter-municipal bodies, operators, industrial companies, developers, social housing organisations, construction firms and engineering consultancies seeking reliable specialist support.
Environmental performance and sustainability are at the heart of our work. We design solutions that protect water quality, reduce pollution, support ecosystems and strengthen infrastructure resilience against climate change. Wherever relevant, we integrate nature-based solutions and low-carbon options, and we help our clients balance cost, risk and environmental impact.
With an experienced team and a trusted network of partners, EcoSync combines high-level expertise with the agility of a lean structure — short decision-making chains, rapid mobilisation and technically robust deliverables.

WHY ECOSYNC
Why our clients choose us
No parent company, no commercial pressure. Our sole focus is finding the right answer for your project.
You work directly with the person who carries out the studies and signs the deliverables. No delegation to junior teams.
We understand the interactions between water cycle components — essential for addressing problems at the interfaces between systems.
We master the regulatory framework — WFD, water reuse, safety plans, master plans — and design our deliverables for French asset owners and operators.

OUR APPROACH
How we work
Small team, full picture
We combine a cross-cutting understanding of the water cycle with the ability to produce concrete, detailed deliverables.
Regulation-ready
Clear assumptions, transparent methods and deliverables that asset owners, operators and contractors can act on immediately.
Sustainable and low-carbon
We seek solutions that minimise energy use and favour nature-based approaches, while remaining realistic for budgets and operations.
Collaborative by nature
Experienced in multidisciplinary teams, we integrate into our clients' organisations, share lessons learned and harmonise practices.
