Companhia de Saneamento Básico do Estado de São Paulo - SABESP SBS

Company Overview

Companhia de Saneamento Básico do Estado de São Paulo (SABESP) is one of the largest water and sanitation companies in the world by population served and is the primary provider of water supply and sewage treatment services in the Brazilian state of São Paulo. The company operates in the public utilities and environmental services sectors, with core activities centered on water collection, treatment, distribution, sewage collection, sewage treatment, and related infrastructure management. SABESP generates most of its revenue from regulated water and sewage tariffs charged to residential, commercial, industrial, and public-sector customers. The company also provides ancillary services tied to sanitation infrastructure, wastewater reuse, and environmental management projects.

SABESP was founded in 1973 through the merger of several regional sanitation entities controlled by the State of São Paulo. The company evolved from a state-focused utility into a publicly traded enterprise listed on B3 in Brazil and on the New York Stock Exchange under the ticker SBS. Its strategic positioning is supported by long-term concession agreements, large-scale infrastructure assets, and a dominant presence in Brazil’s most economically significant state. The company’s scale, regulated asset base, and extensive distribution and treatment networks provide operational advantages that are difficult for competitors to replicate.
