What CORSAN does

CORSAN (Companhia Riograndense de Saneamento) is a regulated water and sewage utility headquartered in Porto Alegre, Brazil, operating under concession contracts with 317 municipalities across Rio Grande do Sul state and serving over 7 million residents through 619 managed locations across 10 operational regions. The company provides potable water production and distribution, sewage collection, and wastewater treatment — with current water coverage of 85% and sewage coverage of 56%, targeted to reach 90% wastewater treatment capacity by 2033. The technology stack is infrastructure-heavy (treatment plants, distribution networks, pumping systems) supplemented by digital customer-facing platforms including a mobile app, virtual agency portal, 24/7 call center, WhatsApp channel, and the ETA 4.0 automated water treatment initiative.

CORSAN's business model is subscription-based and concession-driven: tariffs are contractually predetermined through competitive bidding processes and indexed to IPCA inflation, billed monthly to residential, commercial, and industrial customers. The company operates within a regulatory framework shaped by Brazil's New Sanitation Legal Framework (Law 14.026/2020), and derives supplementary revenue from technical feasibility analysis services for new developments (B2B) and ancillary programs like SoluTrat septic tank cleaning. Customer segments span municipal governments (concession counterparties), residential end-users (the long tail), and commercial/industrial accounts. Marketing and distribution are hybrid: physical service centers (Tudo Fácil), digital self-service, call center, WhatsApp, mobile apps, and community engagement programs including environmental education reaching 300+ community multipliers.

The company was founded on December 21, 1965 by the State Government of Rio Grande do Sul as a state-owned enterprise, privatized via auction in December 2022, and transferred to Aegea Group control in July 2023. Current ownership is held by Saneamento Consultoria S.A. (72.79%) and PARSAN S.A. (27.11%), with board representation from Aegea, Perfin Infra (PE infrastructure), and Kinea Investimentos. Leadership includes CEO Samanta Popow Takimi (appointed June 2023) and CFO/IR Director Bruno Queiroz Jatene. The company secured R$450 million in sustainable financing from the International Finance Corporation in August 2021, and EBITDA margin reportedly exceeded 50% within one year of privatization.
