Agesan-RS

What Agesan-RS does

Agesan-RS (Agência Reguladora Intermunicipal de Saneamento do Rio Grande do Sul) is a public regulatory consortium (Consórcio Público) with autarchic legal personality, founded on December 19, 2018 under Brazilian Federal Law 11.107/05. The agency provides independent regulatory oversight and fiscalization of basic sanitation services — water supply (SAA), sanitary sewage (SES), stormwater drainage (DMAPU), and urban solid waste (RSU) — for more than 100 municipalities across the state of Rio Grande do Sul. Headquartered in Porto Alegre with regional offices in Tramandaí (Litoral) and Caxias do Sul (Serra), Agesan-RS employs 24 staff and operates through Convênios de Regulação and Contratos de Programa with participating municipalities and sanitation service providers including CORSAN, SAMAE Caxias do Sul, COMUSA, SANEP Pelotas, SEMAE São Leopoldo, DAEB Bagé, and private concessionaries.

The agency's core service portfolio centers on tariff regulation, service quality monitoring, and regulatory compliance enforcement, supported by technical methodologies for tariff calculation (Acertar methodology) and alignment with ANA Normas de Referência. Technology infrastructure consists of a Power BI-based Painel de Indicadores dashboard for monitoring sanitation indicators, a centralized Portal de Legislação, an ombudsman system (Ouvidoria) operating through a dedicated 0800 hotline, and the UniAgesan-RS Technical-Institutional Training Program established via Resolução DC nº 04/2026. The agency also conducts public consultations and hearings following PNTP (Programa Nacional de Transparência Pública) guidelines for participatory regulatory agenda definition.

Agesan-RS is funded through municipal fees and regulatory charges borne by participating municipalities and regulated sanitation service providers; the agency does not charge end consumers directly. Revenue is not publicly disclosed. Governance is provided by an Assembly of Mayors (Assembleia Geral de Prefeitos), a Board of Directors (Diretoria Colegiada), and a Superior Council of Regulation (Conselho Superior de Regulação), reflecting collective municipal ownership rather than private equity. The agency is conducting staff expansion through Concurso Público Nº 01/2025 and maintains inter-agency cooperation partnerships with AGER, AGERST, AGERR, and AGESB for regional regulatory coordination.

Broad incumbents

• ARCE (Agência Reguladora de Serviços Públicos Delegados do Estado do Ceará): Ceará state-level multi-sector regulator encompassing sanitation, energy, and other public services. Comparable in regulatory scope over sanitation but broader mandate and state-level authority.
• ANA (Agência Nacional de Águas e Saneamento Básico): National water and sanitation regulator that issues Normas de Referência adopted by Agesan-RS. Comparable in regulatory authority but operating at the federal/national level rather than municipal consortium level.
• AGENERSA (Agência Reguladora de Energia e Saneamento Básico do Estado do Rio de Janeiro): State-level regulator for energy and basic sanitation in Rio de Janeiro. Comparable in sanitation regulatory functions but with a broader multi-sector mandate and state-level authority.
• ARSAE-MG (Agência Reguladora de Serviços de Água e Esgoto de Minas Gerais): State-level sanitation-specific regulator in Minas Gerais. Directly comparable functional mandate (water/sewage regulation) but operating as a state agency rather than intermunicipal consortium.
• ADASA (Agência Reguladora de Águas, Energia e Saneamento Básico do DF): Federal District regulator for water, energy, and basic sanitation. Comparable in regulatory functions over sanitation but covering a different geography (DF) and operating as a state-level agency.

Direct peers

• AGESB (Agência de Saneamento de Bento Gonçalves): Local sanitation agency in Bento Gonçalves, RS — partner of Agesan-RS for inter-agency regulatory collaboration. Comparable in providing sanitation oversight at sub-state/regional level within RS.

• ARIS (Agência Reguladora Intermunicipal de Saneamento de Santa Catarina): Closest structural peer — an intermunicipal regulatory consortium for sanitation services in Santa Catarina, operating under the same Federal Law 11.107/05 model. Directly analogous in governance, mandate, and service portfolio.
