What HYDRETUDES does
Hydrétudes is a French water engineering and environmental consultancy founded in 1990 and operating as a subsidiary of Altereo from its headquarters in Marais, France. The firm specializes in GEMAPI (Gestion des Milieux Aquatiques et Prévention des Inondations), delivering engineering, consulting, and project management services in river and torrent management, flood risk prevention, dam and dike safety, sediment transport, ecological restoration, drone-based topography, and water/wastewater infrastructure engineering. Its client base consists of French public water authorities, municipalities, and intercommunal structures responsible for water and flood-risk competencies.
Hydrétudes has productized portions of its engineering know-how into five proprietary, trademarked tools: HpO® (AI-based pipe break prediction for drinking water networks), Indigau® (automated CCTV processing for sewer inspection), Maltose® (Zero Net Land Take / ZAN trajectory modeling), KIS® (GIS-based utility network management), and ID BAC® (connection inspection control). These tools sit alongside traditional engineering deliverables rather than displacing them, and are bundled into project work or made available through partner channels such as Club Indigau.
The firm deploys approximately 100 GEMAPI specialists across the Altereo agency's national footprint, with the entirety of the business operating on a B2G consulting model. Go-to-market is sales-led, executed through public-sector tenders and project-based quotations, with pricing not publicly disclosed. There is no announced external funding and no disclosed revenue; financial performance is consolidated within Altereo's reporting rather than reported on a standalone basis.

HYDRETUDES competitors and assessment
Company assessmentEmerging players
- Setec: French engineering group with growing water, environment, and digital practices. Overlaps with Hydrétudes on hydraulic infrastructure, environmental studies, and digital project management tools.
Broad incumbents
- Egis: Large French engineering group with water, environment, and territorial planning capabilities. Competes with Hydrétudes for French public-sector water and flood risk engineering work, and is significantly larger and more diversified.
- Suez Consulting (SAFEGE): Water-and-environment consulting arm of the Suez group with deep French municipal water expertise. Direct competitor for GEMAPI-related water infrastructure engineering, asset management, and digital water solutions, operating at significantly larger scale.
- Veolia Water Technologies & Consulting: Global water services giant with French municipal water operations and engineering capabilities. Competes for the same French public water authorities on infrastructure, asset management, and digital water solutions, with vastly greater resources.
- Artelia: Major French engineering consultancy with strong water, environment, and infrastructure practices. Competes for the same French public-sector water engineering and environmental mandates, but at much larger scale and with broader sector coverage (energy, transport, buildings).
- Tractebel (Engie): Large engineering consultancy covering water, environment, energy, and infrastructure. Competes for major French and European water engineering tenders, with a broader portfolio than Hydrétudes but overlapping on flood risk and water network work.
Direct peers
- Altereo: Parent company and direct operating counterpart: Altereo is the parent group, and Hydrétudes' GEMAPI activity is now delivered through all Altereo agencies. Same domain (water, environment, urban planning), same customer base, same services, but at parent-group scale.
- BRL Ingénierie: French engineering firm specialized in water, irrigation, and hydraulic infrastructure. Direct competitor for river, irrigation, and water network engineering projects targeting French public and semi-public clients.
- Antea Group: European environmental and water engineering consultancy with French operations. Closely comparable in service mix (water infrastructure, environment, GIS/digital) and customer base (public water authorities), with comparable headcount scale.
Others
- Bureau Veritas: Global testing, inspection, and certification (TIC) firm with French water and environmental compliance services. Not a direct engineering peer but competes for adjacent water quality, environmental compliance, and asset integrity mandates in the French public-sector market.
