What Syndicat Intercommunal du Bassin d'Arcachon does

Syndicat Intercommunal du Bassin d'Arcachon (SIBA) is a French public intercommunal syndicate established in 1963 that delivers water management, wastewater treatment, and environmental protection services to twelve communes spanning two agglomeration communities (COBAN and COBAS) across the Bassin d'Arcachon territory. Its operational scope covers wastewater collection and treatment, stormwater management, maritime navigation and buoyage, mosquito control, public hygiene, waste and pollution management, and territorial planning instruments including a Local Urban Planning Plan (PLUi). SIBA also runs the l'EAU,ditorium, an educational facility oriented to water literacy for residents and visitors.

SIBA's technical platform is anchored by the REMPAR water-quality monitoring network, an open-data infrastructure, and a set of cartographic applications — E-Navigation, E-Réseaux and E-Urbanisme — that expose utility and territorial data to internal teams and the public. Strategic planning is organized around the Plan d'actions 2024-2028, an accelerated investment program for water, sanitation and environmental infrastructure, and the Contrat Eau & Climat 2025-2030, a multi-stakeholder framework with Agence de l'Eau Adour-Garonne and other partners. Operational execution of certain services is delegated to private partners, notably ELOA and SUEZ EAU FRANCE.

As a public-sector entity, SIBA has no commercial revenue model; it is funded via mandatory contributions from its twelve member communes and through water and sanitation fees levied on users within the basin. There are no equity fundraising events, M&A transactions, or venture-style growth instruments in its structure. Its expansion is therefore expressed through mandate scope, multi-year capital programs, and partnerships rather than through acquisitions or capital markets activity.

Direct peers

• Eau de Paris: Municipal public water authority for the City of Paris. Comparable as a public-law operator of water supply and sanitation with end-to-end control over the service chain, transparency initiatives, and environmental stewardship obligations.
• ELOA: Société d'Exploitation operating sanitation for the 10 communes riveraines du Bassin d'Arcachon under delegation from SIBA. Comparable as the operational arm that runs 24/7 wastewater service within SIBA's perimeter.
• Syndicat Mixte de Gestion de l'Eau: Generic category covering the dozens of French syndicats mixtes that pool water and sanitation competence across multiple municipalities. Comparable governance, financing model (water fees, member contributions), and operational scope to SIBA.
• SUEZ Eau France: Major French water and sanitation utility operator and a direct delegated service partner to SIBA for the Marcheprime and Mios communes. Operates collective sanitation and water treatment at national scale, sharing the same regulatory and operational framework as SIBA's own sanitation system.
• SAUR: French water and sanitation operator serving municipalities, intercommunal authorities, and industrial clients. Directly comparable as a delegated service provider in the same regulatory and operational framework as ELOA and SUEZ inside SIBA's perimeter.
• EPTB (Établissement Public Territorial de Bassin): Network of French public basin-level authorities managing water resources, flood prevention, and aquatic environments at watershed scale. Comparable governance structure to SIBA — public establishment with multi-commune competence over water and environmental management within a defined hydrographic basin.
• SEDIF (Syndicat des Eaux d'Ile-de-France): Public intercommunal water syndicate serving 4.5 million residents in the Paris region. The closest structural peer to SIBA — a French syndicat intercommunal with statutory competence over water service for member communes, using delegated operators for day-to-day operations.

Regional players

• Bordeaux Métropole — Direction de l'Eau: Metropolitan authority managing water and sanitation services for the Bordeaux urban area in the same Nouvelle-Aquitaine region as SIBA. Comparable in regional context and in operating a delegated-service model for collective sanitation across multiple communes.
• Agence de l'Eau Adour-Garonne: Public water agency for the Adour-Garonne basin that co-funds SIBA's Contrat Eau & Climat and Educ'Eau program. Comparable as a public body with basin-level environmental competence, though it funds and regulates rather than directly operates water/sanitation infrastructure.

Broad incumbents

• Veolia Eau France: Largest French water and wastewater utility, providing delegated water/sanitation services across hundreds of communes. Comparable in service portfolio (water supply, wastewater treatment, network management) but operates at national scale rather than a single basin perimeter.
