Syndicat Mixte Du Lac D Annecy

What Syndicat Mixte Du Lac D Annecy does

Syndicat Mixte du Lac d'Annecy (SILA) is a French public inter-municipal syndicate (syndicat mixte) headquartered in Cran-Gevrier, Haute-Savoie, that delivers environmental services across a statutorily defined territory of 116 communes, 7 member intercommunalités, and approximately 319,000 inhabitants. Its mandate covers collective and non-collective wastewater sanitation, treatment and valorization of household and professional waste, lake and aquatic environment management (including GEMAPI flood-prevention duties), and recreational infrastructure such as the Voie Verte greenway around Lake Annecy.

The organization's core technical assets are two purpose-built facilities: Siloé, the principal wastewater treatment plant (UDEP) located in Cran-Gevrier with a public-facing pedagogical gallery, and Sinergie, an energy-recovery unit (Unité de Valorisation Énergétique) in Chavanod that processes non-recyclable waste to produce renewable energy. Supporting infrastructure includes a collective sewer network with interactive mapping, laboratory analysis services for third parties, reed-bed restoration and invasive-species management programs, and navigation equipment for the lake. The technology stack is grounded in conventional civil and environmental engineering rather than digital platforms.

SILA's revenue model is hybrid: regulated annual sanitation fees (Redevance d'assainissement), one-time PFAC contributions for collective sanitation financing, usage-based fees at Sinergie, unit-priced laboratory analyses, and fees for use of the Sevrier dry dock and CATEC platform. As a public-law entity, SILA is funded through member-collectivity budgets and operates without equity fundraising, M&A activity, or commercial revenue disclosure. Its strategic program for the 2026-2032 mandate, anchored in the Plan Lac 2030 initiative, is broadening scope into renewable energy production, water-resource stewardship, and business engagement, signaling incremental expansion of its territorial service mandate rather than commercial growth.

Core offering

SILA is a French public inter-municipal syndicate that delivers essential environmental public services across 116 communes and 319,000 inhabitants around Lake Annecy. Its core offering covers collective and non-collective wastewater sanitation, waste treatment with energy recovery at the Sinergie facility, Lake Annecy protection and aquatic environment management (GEMAPI), and maintenance of the Voie Verte recreational greenway. The organization operates dedicated infrastructure including the Siloé wastewater treatment plant and the Sinergie waste-to-energy unit, funded through sanitation fees, member contributions, and usage-based charges.

Product overview

SILA operates as a unified public environmental services organization offering multiple interconnected services: wastewater treatment through the Siloé plant and collective/non-collective sanitation networks; waste treatment and energy recovery via the Sinergie facility; lake protection and management including navigation equipment; aquatic environment management (GEMAPI) for rivers and wetlands; and the Voie Verte greenway for recreation. The organization functions as a single integrated territorial management entity rather than a platform-plus-modules architecture, with all services coordinated through its central administration in Cran-Gevrier.

Broad incumbents

• Saur: French water services operator (subsidiary of EQT/Caisse des Dépôts) serving municipalities and industrial clients. Comparable to SILA through its delegated public-service contracts for water supply, wastewater treatment, and sanitation infrastructure operation.
• Suez Eau France: Major French water and wastewater services operator serving municipal and industrial clients through delegated contracts. Directly comparable to SILA in wastewater treatment, network operations, and laboratory services, though as a private-sector incumbent with a broader geographic footprint.

Comparable to SILA through its wastewater treatment, sanitation network operations, and water-quality service offerings, though operating under a private rather than public mandate model.

Direct peers
