Agência Nacional de Águas e Saneamento Básico (ANA)

What Agência Nacional de Águas e Saneamento Básico (ANA) does

Agência Nacional de Águas e Saneamento Básico (ANA) is Brazil's national regulatory agency for water resources and basic sanitation, established in 2000 under Law No. 9,984 and headquartered in Brasília with 469 employees. The agency is responsible for regulating federal-domain water resources, overseeing dam safety, and setting standards for basic sanitation services across all of Brazil, operating as the coordinating entity of the Sistema Nacional de Gerenciamento de Recursos Hídricos (SINGREH).

ANA's technology stack centers on a national hydrological monitoring and water resource management platform. Core systems include HIDROWEB (historical hydrological data archive), SNIRH (National Water Resources Information System), SAR (Sistema de Acompanhamento de Reservatórios) — a reservoir-monitoring platform covering 162+ hydroelectric facilities and 500+ reservoirs with ~40 billion m³ total capacity through its SIN, Nordeste e Semiárido, and Outros Sistemas Hídricos modules — and SNISB (National Dam Safety Information System). Supporting platforms include Declara Água (annual water-use declarations), CNARH/REGLA (national water-user registry), Monitor de Secas (drought monitoring), Monitoramento COVID Esgotos (wastewater surveillance), Boleto Online (water-use billing), SEI-ANA (electronic information system), e-Protocolo, the Plataforma Águas Brasil integration layer, and the AVA ANA virtual learning environment. Operational data is fed into these systems through partnerships with ONS, DNOCS, COGERH, AESA, SEMARH, APAC, CERB, INEMA, CODEVASF, COMPESA, IGAM, and ADASA.

The agency's funding and revenue model is that of a Brazilian federal regulatory agency: it is financed through the federal government budget (orçamento federal), and its services — including water-use declarations, billing for federal-domain water use, dam-safety oversight, and sanitation regulation — are provided free of charge to users. ANA does not operate as a commercial entity; it has no disclosed revenue, no parent company beyond the Federal Government of Brazil, no funding rounds, no subsidiaries, and no M&A activity. Its primary constituents are economic agents regulated for water use, state and federal entities within SINGREH, water-resource users across industrial, agricultural, and municipal segments, and basic sanitation service providers subject to ANA's national regulation framework.

Core offering

ANA is Brazil's federal regulatory agency that oversees water resource management and basic sanitation regulation across the national territory. It issues water usage permits, sets and enforces dam safety standards, regulates sanitation service providers, and operates a nationwide network of hydrological monitoring platforms (HIDROWEB, SNIRH, SAR, TELEMETRIA, SNISB, Monitor de Secas). Services are delivered to state water agencies, economic agents (industrial, agricultural, and municipal water users), hydroelectric operators, and sanitation service providers.

Product overview

ANA operates as Brazil's national water and basic sanitation regulatory agency, providing a comprehensive suite of digital platforms and systems for water resources management. The core offerings include HIDROWEB for hydrological data archives, SNIRH for national water resources information, and SAR (Sistema de Acompanhamento de Reservatórios) for reservoir monitoring operations. These are complemented by specialized tools such as the Monitor de Secas (drought monitoring), Declara Água (water use declarations), REGLA (water users registry), and the Monitoramento COVID Esgotos (wastewater COVID monitoring) initiative. The agency also provides institutional systems including SEI-ANA for electronic document management, e-Protocolo for digital submissions, Boleto Online for water use billing, and a virtual learning environment (AVA ANA) for capacity building. The SAR system itself covers three operational modules: Sistema Interligado Nacional (monitoring 162 hydroelectric facilities), Nordeste e Semiárido (tracking 500+ reservoirs), and Outros Sistemas Hídricos (covering Cantareira, Federal District, and Paraopeba systems).
