Confluences

What Confluences does

Confluences Ingénieurs Conseil is a privately held French environmental engineering consultancy (bureau d'études) founded in 1996 and headquartered in Plozévet, Brittany, with a regional office in Montry (Paris Île-de-France). It operates as an independent partnership of five cadres (four active), including the founders Alain Le Quéré (hydraulics/civil engineering), Noureddine Fkihi (agronomy/hydrology, Director since 2008), and Gwennaëlle Le Quéré (ecology). The firm delivers integrated environmental, water, ecosystem, agronomy, and planning services across six practice areas: Hydrology-Hydraulics, Natural Environments-Biodiversity, Water Systems-Water Quality, Ecological Engineering-Plant Engineering, Agronomy-Agriculture, and Territory-Landscape-Cartography.

Its core technology stack combines specialized engineering software (SWMM, HEC1, HEC-RAS, SMS) for hydrological and hydraulic modeling with bioacoustic field tools (Sonochiro, SoundChaser, Batsound) and the SERENA biodiversity database with the Serenomad mobile application, alongside GIS/cartography platforms (Cartolander, QGIS, ArcView). The firm holds a French Ministry of Ecology agrément (approval) for safety inspections of Class C dams and dikes, which provides a regulated credential for hydraulic structure diagnostics, design, and works supervision.

Revenue is generated exclusively through project-based professional services contracts with public institutions (ministries, regional and departmental councils, municipalities, intermunicipal structures, water agencies) and private developers and operators (real estate promoters, tourism parks, Aéroports de Paris, Disney, water network concessionaires, SEMs). The go-to-market is sales-led and direct: client engagement is built on referrals, public-sector procurement, and the firm's regulatory credentials, with no disclosed public pricing or packaged products.

Core offering

Confluences Ingénieurs Conseil is a French environmental and planning consulting firm (bureau d'études) that delivers integrated multidisciplinary engineering studies in hydrology-hydraulics, natural environments and biodiversity, water systems and water quality, ecological and plant engineering, agronomy-agriculture, and territory-landscape-cartography. Services are sold as project-based consulting engagements to public administrations (ministries, regional and departmental councils, municipalities, water agencies) and private operators (real estate developers, airports, tourism operators, water network concessionaires). The firm also holds Ministry of Ecology approval to perform safety inspections, diagnostics, design, and construction monitoring for Class C dams and dikes.

Product overview

Confluences Ingénieurs Conseil is an environmental and planning consulting firm (bureau d'études) offering integrated multidisciplinary services. The firm provides six main consulting service areas: Hydrology-Hydraulics (watershed studies, hydraulic modeling, rainwater management), Natural Environments-Biodiversity (ecological inventories, species monitoring), Water Systems-Water Quality (quality monitoring, wetland expertise), Ecological Engineering-Plant Engineering (habitat restoration, urban ecology), Agronomy-Agriculture (soil studies, urban farming), and Territory-Landscape-Cartography (landscape analysis, GIS, environmental communication). The services are delivered as professional consulting engagements rather than packaged software products.

Functional benefit

Products and services

• Hydrologie – Hydraulique (Hydrology and Hydraulics) Integrated watershed studies, hydraulic modeling, urban stormwater management and alternative sanitation techniques, and design/dimensioning of hydraulic structures. The firm is approved by the French Ministry of Ecology to perform safety inspections of Class C dams and dikes, including diagnostics, design, and construction monitoring. Intended for public administrations, aménageurs, and industrial operators needing flood-risk and water-management expertise.
• Milieux Naturels – Biodiversité (Natural Environments and Biodiversity) Ecological monitoring, fauna-flora inventories, characterization and prioritization of ecological issues, advisory on management and conservation, ecological mediation, and biodiversity data management (including via the SERENA database and Serenomad mobile application). For clients needing ecological state-of-knowledge and regulatory baseline studies for development projects and protected species monitoring.
• Hydrosystème – Qualité des eaux (Water Systems and Water Quality) Water-quality monitoring and management advisory, hydro-ecological expertise, regeneration of aquatic environments, and wetland characterization using AFB methodology. For public actors, water agencies, and developers requiring aquatic-environment diagnostics and regulatory studies (loi sur l'eau).
• Génie écologique – Génie végétal (Ecological Engineering and Plant Engineering) Habitat and ecological milieu recreation and restoration, urban ecology and Green/Blue Corridors (Trame Verte et Bleue), brownfield and derelict-land reconquest, and invasive species control. For developers, municipalities, and industrial operators integrating biodiversity into works.
• Agronomie – Agriculture (Agronomy and Agriculture) Agronomic and pedological (soil) studies, urban agriculture, rural development, and agro-environmental measures, with an emphasis on agrarian landscape structures. For municipalities, aménageurs, and developers needing soil diagnostics and agro-environmental expertise.
