Agência Reguladora Intermunicipal de Saneamento

What Agência Reguladora Intermunicipal de Saneamento does

ARIS (Agência Reguladora Intermunicipal de Saneamento) is a Brazilian public-law consortium headquartered in Florianópolis, Santa Catarina, established to regulate municipal sanitation services on behalf of its member municipalities. Operating under Brazilian consórcio público statutes, ARIS holds delegated regulatory authority over water supply, sewage, and related sanitation services, currently serving 211 municipalities across Santa Catarina state. The organization is staffed by approximately 26 employees and operates through a headquarters office plus six regional offices located in Chapecó, Videira, Lages, Maravilha, Rio do Sul, and Joinville, enabling statewide coverage of regulatory inspection, tariff review, and concessionaire oversight.

The agency's operational backbone consists of two named digital platforms — the ARIS Regulatory Portal (Portal Regulatório ARIS), which supports regulatory filings and public transparency, and SISARIS, the internal regulatory management system. ARIS also publishes an annual Agenda Regulatória (the most recent covering 2026) that defines the regulatory pipeline, and works alongside more than 20 affiliated municipal associations and IT/governance consortia. Strategic technology and policy partnerships include CIGA (Consórcio de Informática na Gestão Pública) for shared IT infrastructure and ABAR (Associação Brasileira de Agências de Regulação) for integration into the national regulatory community.

ARIS's business model is structured as a public-sector regulatory body rather than a commercial enterprise: it is funded through recurring regulatory fees and contributions from its 211 member municipalities, with no equity funding, no disclosed ARR, and no commercial product pricing. The value proposition for member municipalities is consolidated, specialized regulatory capacity that would be uneconomic for each municipality to replicate independently. As a non-investable public-law entity, ARIS's analytical relevance is as a benchmark for the intermunicipal regulatory model in Brazilian sanitation rather than as a private investment target.

Closest functional analog at larger scale in Brazil's most economically significant state.
• ARSAE-MG - Agência Reguladora de Serviços de Abastecimento de Água e de Esgotamento Sanitário do Estado de Minas Gerais: Minas Gerais' sanitation services regulator focused exclusively on water and sewage — a near-identical mandate to ARIS and the most directly comparable single-purpose state sanitation regulator in Brazil.
• AGERSA - Agência Estadual de Regulação dos Serviços Públicos Delegados do Rio Grande do Sul: Rio Grande do Sul's state regulator for delegated public services with sanitation oversight authority. A neighboring-state peer with comparable scope, serving as a regional benchmark for ARIS.
