What CASAN does
CASAN (Companhia Catarinense de Águas e Saneamento) is a state-owned mixed-economy water and sanitation utility headquartered in Florianópolis, Brazil, serving 194 municipalities across Santa Catarina and one in Paraná. Founded in 1970, the company provides potable water supply and sewage collection/treatment to 2.911 million people through 855,166 water connections and 387,767 sewage connections, operating an infrastructure footprint that includes 338 water treatment stations, 54 sewage treatment plants, 15,424 km of water distribution network, and 2,117 km of sewage collection network. CASAN maintains a 97.38% water supply index and produced 800,500 m³ of treated water per day in 2024, with 34.95 million m³ of sewage collected over the same period.
The company's technology is grounded in conventional water and sewage treatment processes — including UASB, MBBR, activated sludge, slow filtration, dissolved air flotation, and stabilization lagoons — supported by a regional laboratory network for water quality monitoring and the CIOM integrated operations center for real-time visibility. Customer-facing technology includes the CASAN mobile application (iOS/Android), the e-CASAN self-service portal, online.casan.com.br, 24-hour WhatsApp service, and the FalaBR-integrated ombudsman. CASAN is publicly traded (bvmf:CASN4), majority-owned by the Government of Santa Catarina, with the board including a minority shareholders' representative.
CASAN's revenue model is regulated monthly tariff billing across Residential, Residential Social, Commercial, Micro and Small Commerce, Industrial, and Public Special categories, with sewage charged at 100% of the water tariff and TFDI (fixed infrastructure availability) fees layered on top. Ancillary revenue includes one-time connection, inspection, and meter-testing fees. Tariff adjustments are authorized by state regulators (ARESC, ARIS, AGIR, CISAM-SUL), with a 5.80% increase applied from April 2026. The go-to-market is direct-to-consumer through physical agencies and digital self-service, plus B2G concession, program, and shared-management contracts with municipal governments. Major infrastructure expansion has been financed through international development loans — R$404 million from JICA (2010/2012) and 100 million euros (~R$270 million) from AFD (October 2012) — within a R$1.2 billion 2014-2017 investment plan targeting an increase in sewage coverage from 18% to 45%.
