SYNDICAT DU BASSIN HERS GIROU

What SYNDICAT DU BASSIN HERS GIROU does

Syndicat du Bassin Hers Girou (SBHG) is a French public territorial water management authority (syndicat de rivière) operating under French public law as an établissement public de coopération intercommunale. Founded in 1999 as the Syndicat Mixte du Bassin Versant de l'Hers-Mort (SMBVH), the organization is headquartered in Toulouse and is responsible for managing the Hers-Mort and Girou river basins across the Haute-Garonne, Aude, and Tarn departments. It holds GEMAPI (Gestion des Milieux Aquatiques et Prévention des Inondations) competencies and serves approximately 52 member municipalities and intercommunalities (EPCI), including Toulouse Métropole, SICOVAL, Terres du Lauragais, Frontonnais, and Coteaux du Girou. The entity is governed by an elected Comité Syndical and operates through a Commission Locale de l'Eau (CLE) comprising 31 local authority representatives, 14 user representatives, and 7 state representatives.

SBHG's core operational framework is the SAGE Hers-Mort Girou (Schéma d'Aménagement et de Gestion des Eaux), a comprehensive water management plan approved by prefectural decree on May 17, 2018, after multi-year development spanning 2013-2017. Under this framework, the syndicate executes a multiannual Programme Pluriannuel de Gestion (PPG) for river maintenance, ripisylve reconstitution, river bed restoration, wetland restoration, flood prevention infrastructure, and erosion control. It also developed an interactive stormwater sensitivity web application (eaux-pluviales.hersgirou.fr) covering 60 sub-basins, providing geospatial analysis of slope, geology, land use, runoff sensitivity, and parcel data. Technical engineering work is supported by contracted consulting firms (Otéis and Envilys) using the Pégase water quality modeling tool.

SBHG does not operate a commercial business model. As a public establishment, it is funded through member municipality contributions and public grants, primarily from Agence de l'Eau Adour-Garonne and Région Occitanie. The organization employs 8 staff and engages external engineering and consulting partners to deliver hydraulic, hydrological, and water quality studies. It runs an educational program ("Classes de l'eau") in partnership with CPIE Terres Toulousaines, producing the magazine "Au fil de l'Hers" and supporting river restoration works including the 2022 acquisition of approximately 7,000 m² of riparian land at Cuq Toulza along the Girou.

Others

• BRGM (Bureau de Recherches Géologiques et Minières): France's public geological survey, providing hydrogeological data, models, and expertise that underpin river basin management activities similar to SBHG's. Acts as an upstream knowledge provider and technical counterpart for syndicats undertaking hydraulic and water quality studies.
• Office Français de la Biodiversité (OFB): National public operator supporting biodiversity and water-environment policy implementation. While not a direct competitor, OFB is a key regulatory and operational counterpart to SBHG in aquatic environment restoration, ripisylve management, and species protection across French watersheds.

Broad incumbents

• Agence de l'Eau Adour-Garonne: The basin-level public water agency that funds SBHG and other syndicats across the Adour-Garonne basin. A larger, broader incumbent that defines programming cycles, allocates funding, and sets water policy direction that SBHG and similar syndicats implement locally.
• EPTB Seine Grands Lacs: Large-scale Établissement Public Territorial de Bassin responsible for water resource management and flood prevention across the Seine basin, including reservoir infrastructure. While much larger and nationally significant, it shares SBHG's public-law structure, GEMAPI-style mandate, and integrated water management mission.
• EPTB Loire: Major public basin authority managing the Loire river system, sharing SBHG's GEMAPI-style competencies, multi-region coordination role, and reliance on basin-agency funding. Operates at a national scale and offers a broader-incumbent comparison.

Regional players

• SMBV Vidourle (Syndicat Mixte du Bassin du Vidourle): Public river basin syndicate managing the Vidourle river between Hérault and Gard departments. Comparable in scale and mandate to SBHG, with a similar focus on flood prevention and river restoration, though operating in a different Occitanie sub-region.
• Syndicat Mixte du Bassin de l'Or: Public river and lagoon basin management syndicate in the Hérault department. Comparable in structure and small-team scale to SBHG, with a similar mix of water quality, flood prevention, and ecosystem restoration mandates within the Occitanie region.

Direct peers

• Institution Adour: Public basin authority coordinating water management on the Adour river system in southwestern France. Operates with a comparable public-law structure, multi-departmental reach, and integrated water resource mandate to SBHG, though on a larger and more coastal catchment.
• Compagnie d'Aménagement des Coteaux de Gascogne (CACG): Public water and agricultural resource management company operating in the Gascogne coteaux region, sharing SBHG's broader Occitanie/southwestern France geography and its combined mandate of water resource management, irrigation infrastructure, and rural flood control. Significantly larger in scale but functionally analogous.
• SMIVAL (Syndicat Mixte de la Vallée de l'Aude): Public river basin syndicate managing the Aude river valley, with overlapping Adour-Garonne/Rhône-Méditerranée watershed responsibilities and a comparable mission of river restoration, flood prevention, and SAGE implementation. Operates as a direct functional peer to SBHG within the same broader Occitanie territory.
