What Feljas & Masson does

Feljas & Masson is a privately held French engineering group founded in 1962 and headquartered in Laval, France, specializing in the design, construction, and installation of hydraulic systems for the water sector. Its core offering covers the full project lifecycle — water collection infrastructure (borewells, intakes), pumping stations, water and wastewater treatment plants, storage and buffer tanks, rainwater management, and SCADA-based remote monitoring. The firm operates an integrated delivery model that combines an in-house hydraulic design office using 3D scanning and tools such as Autodesk Inventor and AutoCAD, an ISO 9606-1 / EN 287-1 certified mechanical welding and fabrication workshop, electrical engineering and automation services, in-house logistics, on-site assembly and supervision, and 24/7 maintenance and emergency support.

The company serves municipalities, public water authorities, and select industrial clients through project-based contracts won via competitive tenders. Named reference customers include Eau de Paris, the Addis Ababa Water and Sewerage Authority (AAWSA), SEEG in Gabon, JIRAMA in Madagascar, SNCF, and a range of French communes, with project values disclosed ranging from approximately €52K for smaller borewell installations to €2.59M for major treatment-plant renovations. Internationally, Feljas & Masson operates wholly-owned subsidiaries in Ethiopia (since 1974), Gabon (2006), Algeria (2007), Georgia (2011), Uzbekistan, and a Brittany regional branch acquired in 2014, collectively accounting for roughly half of its 110+ employees and supporting work in over 50 countries with 1,600+ cumulative reference projects.

Revenue is generated almost entirely through professional-services project delivery, complemented by recurring maintenance contracts on installed equipment. Distribution is exclusively direct enterprise sales to public-sector and utility buyers, with no intermediaries. The firm is associated with French industry bodies including FNTP, Synteau, QUALIFELEC, SNECOREP, and Aquavalley, and its ownership has been dominated by SONEPAR since 1988, with current leadership under Chairman and CEO Bernard de Champs de Saint-Léger.

Recent moves11 records

Expansion highlights5 records

Broad incumbents

• Altrad Group: Altrad Group provides industrial services and equipment — including mechanical fabrication, welding, and site services — to energy, water, and process industries. It overlaps with F&M's mechanical welding/fabrication and on-site assembly capabilities and can act as either a partner or competitor on large industrial water projects.
• Suez Eau France: Suez Eau France is one of France's two dominant water utility operators and infrastructure contractors, with which F&M has partnered on Algiers wastewater projects. Suez competes broadly across the same municipal water-infrastructure value chain as F&M but as a vertically integrated incumbent combining utility concessions, treatment plant construction, and operations.
• Veolia Water Technologies: Veolia Water Technologies designs and supplies water and wastewater treatment plants, including pumping and lift-station equipment, for municipalities and industrial clients worldwide. It operates as a broader incumbent with engineering, equipment supply, and operations, intersecting F&M's treatment plant and pumping station scope.
• Saur (Groupe Saur): Saur is a major French water and wastewater utility and infrastructure contractor serving municipalities, with overlap in pumping-station construction and water-treatment plant design. As a broad incumbent it competes for many of the same French municipal tenders while also offering delegated operation services that F&M does not.

Others

• Saint-Gobain PAM: Saint-Gobain PAM is the leading French supplier of ductile iron pipes, fittings, and hydrants for drinking water distribution and wastewater networks. While not a direct construction competitor, it is an upstream supplier into the same municipal water-infrastructure value chain and a potential partner or competitor for the piping elements of F&M's projects.

Direct peers

• Sogea Environnement (Vinci Construction): Sogea Environnement is the water and environmental infrastructure arm of Vinci Construction, operating in the same French hydraulic-infrastructure construction space as F&M — building drinking water networks, pumping stations, and wastewater treatment plants for municipalities and public utilities. Comparable scope, comparable customer base, but with much greater balance-sheet scale.
• NGE (Nouvelles Générations d'Entrepreneurs): NGE is a major French mid-market infrastructure group that participates in water and hydraulic civil works tenders for municipalities and concessions. It competes with F&M for the same French public water-infrastructure bids while also operating at significantly larger scale across transport and earthworks.
• SADE CGTH (Veolia): SADE CGTH, the water-network construction subsidiary of Veolia, is a direct peer — both design and build pumping stations, lift stations, and water/wastewater networks for French and international municipalities. F&M has worked as a specialized subcontractor to SADE CGTH on the Puerto Cortes Honduras project, confirming direct overlap in scope, customer base, and delivery model.
