What DMeau does

DMeau is a French environmental engineering consultancy (bureau d'études environnementales) founded in 2004 and headquartered in Janzé, Brittany. The firm operates as a SARL (private limited company) with €8,000 in social capital and a team of approximately 10 professionals organized into two specialized poles: Hydraulique/Hydrologie (stormwater, wastewater, water law, sanitation zoning) and Ecologie (naturalist expertise, fauna/flora inventories, wetland characterization, ecological continuity studies). Its service portfolio spans more than 25 distinct offerings, including regulatory dossiers (Loi sur l'eau, environmental impact assessments, CNPN protected species derogations, Natura 2000 evaluations), urban planning documents (PLU, PLUi, SCoT, Carte Communale), and field investigations using specialized equipment such as SM4/SM5 acoustic recorders and Pettersson M-500 microphones for bat detection.

The firm serves a dual client base of public-sector entities (communes, intercommunalités, départements, and métropoles primarily in the Grand Ouest region — Bretagne and Pays de la Loire) and private developers (real estate, retail, energy infrastructure). Named public clients include Rennes Métropole, Saint-Malo Agglomération, Angers Loire Métropole, Départements of Morbihan, Ille-et-Vilaine, and Côtes d'Armor; named private clients include Lidl, Bouygues Immobilier, Viabilis, and GRTgaz. Distribution is exclusively direct, with no intermediaries; revenue is generated through project-based consulting fees, public procurement contracts, and referral-driven engagements.

DMeau maintains a network of approximately 12 strategic partnerships with landscape architects and urban planning firms (A3 Paysage, Archipole, K-Urbain, L'Atelier DYs, Origami, Urbaction, OKARE, Sitadin, Atelier TEC, La Boite De L'Espace) and is associated with two complementary structures, IetG (IGRAD) and Yris Environnement, that extend service capacity. The company is founder/management-owned, with no disclosed external funding, acquisitions, or institutional investors.
