What SETEC HYDRATEC does

Setec Hydratec is a French engineering consultancy, founded in 1974 and headquartered in Paris, that delivers project management, design studies, construction supervision, and technical assistance for water systems, hydraulic infrastructure, and aquatic environments. The firm operates as the hydraulic and water-engineering subsidiary of the broader setec group (founded 1957), serving French and international public authorities — including ministries, departmental councils, metropolitan authorities, port authorities, and large private infrastructure operators — across transport, water, environment, energy, and buildings sectors. Notable engagements span the 107km Seine-Nord Europe Canal, the Canamarne hydraulic infrastructure for Aéroports de Paris, the Red Sea to Dead Sea water transfer, and offshore wind port-logistics projects such as the InFloW feasibility study at Brest Port.

The firm's technology base spans multidisciplinary engineering — civil, geotechnical, hydraulic, structural, transport, and environmental — supported by proprietary software including PYTHAGORE for spatial structural modelling of complex bridges (used on Millau Viaduct and Mohammed VI Bridge), HYDRA for hydrological and hydraulic modelling, and a Digital Portfolio Solution for consolidated project scheduling and performance monitoring on transnational programs. The group also operates a dedicated training campus (Campus setec) and embeds sustainability commitments (annual Scope 1/2/3 carbon measurement since 2008, ERC sequence compliance) into its Go/No-Go project selection process under the 'Ingénieurs & Citoyens' ethos.

Revenue is generated through project-based professional services contracts, with the parent setec group reporting €560 million in turnover for fiscal year 2025 across 4,200 employees, of which 30% was generated internationally across 25+ countries. The group operates under the Trajectoires 2030 strategic plan built on four pillars — ecological transition, digital transformation, international development, and talent cultivation — and has actively expanded its structure in 2025 via new subsidiaries (revoco for PMO services, setec offshore solutions group), the sealand projects acquisition, and the integration of Encis Environnement into setec énergie environnement.
