What Direction Départementale Territoires Mer DDTM does

Syndicat Mixte du Bassin de la Seudre (SMBS) is a French public territorial mixed syndicate (établissement public de coopération environnementale) headquartered at 17 rue de l'électricité, 17200 Royan, Charente-Maritime. It serves as the designated "structure porteuse" responsible for coordinating integrated water resource management and flood prevention across the Seudre river basin and its 32 sub-basins, spanning from La Seudre continentale to the estuarine marshes. SMBS implements five major public policy instruments: the SAGE (Schéma d'Aménagement et de Gestion des Eaux, approved 7 February 2018), the PAPI (Programme d'Actions de Prévention des Inondations, 2018-2023 with Avenant 2 in 2024), the PTGE (Projet de Territoire pour la Gestion de l'Eau, 2024-2028 action programme), the PPG (Programme Pluriannuel de Gestion, 2024-2033, comprising 34 action sheets across 10 themes), and the Seudre ALABRI vulnerability diagnostics programme for private property owners in flood-risk zones.

The organisation operates through institutional governance via the Commission Locale de l'Eau (CLE), which has held 31 meetings through January 2026, bringing together state agencies, local authorities, water users, and environmental stakeholders. Its technical operations rely on GIS/cartographic tools, a monitoring dashboard tracking SAGE/PTGE/PPG indicators, and external hydraulic and hydromorphological modeling performed by engineering bureaux (including BRGM and CACG). Real-time monitoring data is integrated from the Agence Régionale de la Biodiversité Nouvelle-Aquitaine, SHOM, and ADES platforms. SMBS provides free building vulnerability diagnostics to property owners and manages subsidy disbursements of up to 100% of eligible renovation costs.

SMBS is governed by an elected comité syndical and directed by Jean-Philippe David. It is jointly managed and hosted with the Communauté d'Agglomération Royan Atlantique (CARA). All services are provided free of charge to end beneficiaries, with operating costs funded entirely through public subsidies from the French State (DDTM17, DREAL Nouvelle-Aquitaine), the Département de Charente-Maritime, CARA, CCBM, and Agence de l'Eau Adour-Garonne. There is no commercial revenue model; SMBS is a pass-through administrator of public policy instruments rather than a market participant. The organisation has approximately 25 employees and is actively recruiting two additional chargés de mission.

Direct peers

• EPTB Charente: Public basin authority managing the Charente river watershed, the adjacent watershed to the Seudre. Comparable in function, regional setting, and mixed-union structure, making it a natural geographic and operational peer for SMBS.
• Syndicat Mixte d'Aménagement de la Boutonne (SMAB): Mixed syndicate managing the Boutonne river basin in the same Nouvelle-Aquitaine region, with similar responsibilities for water management, ecological restoration, and flood prevention. Closely comparable in size, structure, and territorial scope to SMBS.
• EPIDOR (Établissement Public Territorial du Bassin de la Dordogne): French EPTB managing the Dordogne river basin with a similar integrating structure for SAGE, water planning, and flood prevention. Directly comparable as a public basin authority coordinating multiple water policy instruments across a defined watershed.
• Institution Adour: Public institution managing the Adour river basin in Nouvelle-Aquitaine and surrounding regions, with comparable integrated water management and flood prevention responsibilities. Operates in the same broader regional water policy ecosystem as SMBS.

Emerging players

• EPTB Vilaine: Public basin authority managing the Vilaine watershed in western France, with comparable SAGE-implementation and flood prevention functions. Operates in a different geography but exercises the same EPTB mandate and multi-instrument coordination model.

Broad incumbents

• EPTB Loire: Public territorial basin establishment coordinating Loire river water policy and flood prevention. Shares the EPTB model and SAGE-style governance approach applicable to SMBS, though at a much larger river-system scale.
• EPTB Seine Grands Lacs: Larger public authority managing the Seine basin and its major reservoir lakes, with overlapping responsibilities in flood prevention, water resource management, and SAGE-equivalent governance. Comparable in function but operates at significantly greater scale and geographic scope than SMBS.
