DAAE Rio Claro

What DAAE Rio Claro does

DAAE Rio Claro (Departamento Autônomo de Água e Esgoto de Rio Claro) is a municipal autonomous water and sewage utility (autarquia) established on December 5, 1969, by Municipal Law 1,144, serving the entire city of Rio Claro in São Paulo state, Brazil. The utility operates two water treatment plants — ETA 1 'José Maria Pedroso' (40% of supply) and ETA 2 'José Crespo' (60%) — drawing raw water from the Rio Corumbataí and Ribeirão Claro, and distributing treated water through a city-wide network of transmission mains (adutoras up to 500mm diameter), pumping stations, and reservoirs to approximately 200,000+ residents across multiple districts including Assistência, Ajapi, Ferraz, and Cidade Nova. The organization is supported by a lean team of 37 employees and uses a georeferencing (GIS) system for network mapping and operational tracking.

DAAE generates revenue primarily through regulated water supply tariffs and sewage collection fees, set by ARES-PCJ (the regulatory agency for the PCJ river basin) under a parametric formula based on IPCA/INPC inflation indices. A 14.80% tariff increase was approved in June 2021 (Resolution 385) after a 24-month adjustment gap. Secondary revenue comes from service fees (hydrometer cut/reconnection at R$54.28, sidewalk cut/reconnection at R$65.16) and active debt recovery through the Refis program, which generated R$9 million in negotiated debts in 2021 against an R$85 million active debt portfolio. Notably, sewage treatment services in Rio Claro are operated by BRK Ambiental under a separate concession, while DAAE handles water supply — a structural division between the two services.

The utility operates across multiple service channels including a toll-free 0800-019-0505 hotline (24/7), the CADU digital customer service platform (Unicidades) launched in April 2026 via WhatsApp and mobile app, the ePortal for bill reprint and service requests, in-person service at headquarters (Avenida 8A, 360, Cidade Nova), and the 'Daae na Escola' educational outreach program. As of 2025, the utility is undergoing a public consultation process on potential transformation from an autarquia into a public company (empresa pública), with public hearings held in February and May 2025.
