What D2M Environnement does

D2M Environnement is a French environmental engineering consultancy founded in 2025 and headquartered in Payra-sur-l'Hers (Aude), with a second operational base in Vaucluse. The firm employs three co-founders — Sébastien Dollé, Antoine Marty, and Clément Masse — who between them hold approximately 25 years of experience in hydraulic and environmental engineering, including prior roles as agency managers and as chef de service Grand Cycle de l'Eau inside a local authority. D2M's service offering is structured around four integrated lines for French local public-sector clients: Schémas Directeurs et Zonages (master planning and zoning for drinking water, wastewater, stormwater, and external fire protection), Expertise Service Public (technical and financial audits, management-mode selection, and contract implementation support), Dossiers Réglementaires (Loi sur l'Eau, PGSSE, catchment protection perimeters, ICPE filings), and Études Hydrauliques (sizing and design of hydraulic structures). Underlying technology consists of conventional hydraulic engineering analysis tools; the firm is not software-led and does not disclose proprietary platforms.

The business model is project-based professional services: engagements are tendered by French communes and intercommunal structures (EPCI) and priced per project, with no published rate card or recurring revenue component. Go-to-market is sales-led and direct, relying on the founders' personal networks, a LinkedIn presence, a downloadable brochure, and a single contact email. Geographic reach already extends across 30+ French departments, an indicator that the founders are leveraging prior client relationships. The firm positions itself explicitly on independence from industrial groups that typically also bid on delegated water-service contracts, framing that independence as a trust and objectivity advantage for public buyers. The company is bootstrapped and founder-owned, with no institutional investors, parent entity, or M&A activity disclosed; it pursues an ISO 9001-inspired quality approach but is not yet certified.

Direct peers

• Naldeo: Naldeo is a French independent engineering consultancy focused on water, environment, and infrastructure for public-sector clients. Its size, service mix (master plans, hydraulic studies, regulatory dossiers), and target market closely mirror D2M's profile.
• SCE (Setec group): SCE is a French independent environmental engineering consultancy providing water, sanitation, and stormwater studies for local authorities. Its service portfolio and public-sector client base directly overlap with D2M's.
• Cabinet Merlin: Cabinet Merlin is a French independent engineering firm specializing in water, environment, and infrastructure for collectivités. It produces Schémas Directeurs and regulatory files analogous to D2M's core offerings.
• Altereo: Altereo specializes in water-cycle engineering and public-service expertise for French communes and EPCIs, including Schémas Directeurs, audits, and maîtrise d'œuvre studies — a near-direct functional peer to D2M.

Broad incumbents

• Safege (Suez Consulting): Suez Consulting's engineering division offers water and environmental engineering studies, master plans, and regulatory dossiers for French collectivités. It is a much larger, incumbent competitor to D2M, but operates under a major water group — which is precisely the independence gap D2M exploits.
• Artelia: Artelia is a major French engineering group with dedicated water, environment, and urban hydraulics practices serving public authorities. It competes for the same Schémas Directeurs and hydraulic study mandates as D2M, but at much larger scale.
• Egis Eau: Egis operates an environmental and water engineering practice (Egis Eau) that delivers master plans, regulatory files, and hydraulic studies for French local authorities — directly comparable services to D2M's portfolio but with substantially greater resources.

Emerging players

• Verdier (VRD & Environnement): Verdier is a smaller French engineering consultancy with water and environmental competencies serving local authorities. It is comparable to D2M as a regional, smaller-scale peer in the same consulting niche.
