Syndicat mixte Trigone

What Syndicat mixte Trigone does

Syndicat mixte Trigone is a French public mixed syndicate (syndicat mixte) headquartered in Auch, Gers department, France, founded in 2001. It operates three departmental competencies delegated by member collectivities: household waste management, drinking water production and distribution, and collective and non-collective sanitation. The organization serves approximately 202,386 inhabitants for waste services and 35,000 inhabitants for water production, spanning 117 communes in the Gers department and one commune in Hautes-Pyrénées. Physical infrastructure includes 33 déchèteries, 6 waste transfer centers, an ISO 14001 / OHSAS 18001-certified controlled landfill (ISDND) with biogas-to-biomethane recovery, 2 water production stations (Arros and Pléhaut) producing a combined ~9,000 m³ daily, and 1,030 km of water distribution networks across 20 reservoirs and 5 pumping stations.

Trigone operates through direct public management (régie) and runs two subsidiary public limited companies: SPL Trigone (created 2011), a wholly-owned waste-transport fleet operator, and SPL Tri-0 (created 2022, jointly with SMTD65 and SYSTOM des Pyrénées), which operates the new interdepartmental sorting center at Masseube inaugurated April 11, 2026 with 35,000 tonnes/year capacity serving ~600,000 inhabitants. Revenue is generated through member contributions (two-thirds of waste competency resources come from SICTOM and Grand Auch Cœur de Gascogne), water sales to distribution syndicates, sanitation fees (redevances), professional déchèterie credit fees (€8.40 TTC per passage), and eco-organism contributions for material valorization. The organization is governed by a Syndical Committee of elected representatives from member communes, intercommunalities, and the Gers Departmental Council, with Francis Dupouey as President.

Citizen-facing digital services include an online water subscriber portal (abonneseau.trigone-gers.fr), a Horanet-powered déchèterie credit management platform, monthly water-bill installment payments, free composter distribution, a reusable dish rental platform for events, and Panneau Pocket real-time alerts. The customer base is entirely public — communes, intercommunalities, departmental council, and the residents of the member territories — with no exposure to private commercial concentration.

Broad incumbents

• Eau de Paris: Eau de Paris is the municipal public operator producing and distributing drinking water in Paris. Comparable to Trigone\u2019s water-production/distribution competency under public-service-delegation model, but at urban scale and serving as an incumbent rather than a rural operator.
• SEDIF (Syndicat des Eaux d'\u00cele-de-France): SEDIF is the public syndicate producing and distributing drinking water to ~4 million inhabitants across most of \u00cele-de-France. Broader-incumbent peer to Trigone on the water competency\u2014same syndicat-mixte model, similar production-station + distribution-network economics, but vastly larger scale.
• Suez S.A. Suez is a large French-headquartered environmental services group active in water, waste, and sanitation. Directly comparable service offering to Trigone\u2019s three competencies, but operates at national/international scale as a private commercial incumbent rather than a single-department public operator.
• Veolia Environnement: Veolia is a global water and waste management operator with delegated public service contracts in France. Comparable to Trigone on waste/water/sanitation service portfolio, but operates commercially across hundreds of municipalities as a broad incumbent rather than as a single-territory public syndicate.

Direct peers

• SYSTOM des Pyr\u00e9n\u00e9es: SYSTOM is the public syndicate coordinating waste treatment across the Pyr\u00e9n\u00e9es. It is a direct comparable to Trigone\u2014same syndicat-mixte legal form, same household waste/sorting mission\u2014and the third partner in SPL Tri-0 alongside Trigone and SMTD65.
• SMICVAL (Syndicat Mixte Intercommunal de Collecte et de Valorisation du Libournais): SMICVAL is a public mixed syndicate managing household waste collection, sorting, and valorization in Gironde. Comparable to Trigone on waste-only mandate, multi-competency d\u00e9ch\u00e9terie network, and intercommunal member governance.
• DECOSET (Syndicat Mixte Centralis\u00e9 de Traitement des Ordures M\u00e9nag\u00e8res): DECOSET is the public mixed syndicate operating waste treatment infrastructure (incineration with energy recovery) in the Toulouse metropolitan area. Direct peer to Trigone on waste-treatment mandate and syndicat-mixte governance, but at much larger urban scale with waste-to-energy rather than landfilling as the primary disposal route.
• SMTD65 (Syndicat Mixte de Traitement des D\u00e9chets des Hautes-Pyr\u00e9n\u00e9es): SMTD65 is a French public mixed syndicate managing waste treatment in Hautes-Pyr\u00e9n\u00e9es. It is a direct peer of Trigone and co-shareholder of SPL Tri-0, operating an interdepartmental sorting center together\u2014closely aligned on competencies, scale, and public-service-delegation model.
