Sabesp is detailing a regulator-approved adjustment to its water and sewage tariffs. The company reports a 10.6% increase in the equilibrium rate, which is the technical rate level used in the regulatory framework. This change reflects factors such as recognition of the regulatory asset base, operating expenses, non-manageable costs, compensatory adjustments from the prior regulatory cycle, and other financial items.
After incorporating market effects, inflation measured by IPCA between July 2024 and October 2025, and tax items related to PIS/COFINS, Sabesp calculates that the average tariff applied to users will rise by 6.5%. The company links part of the improvement in operating items to a higher number of connections and volumes, driven by anticipated universalization of services, while also noting the end of rate coverage for the Alto Tietê PPP as a negative factor. These changes define the new price levels customers will pay going forward.
Companhia de Saneamento Básico do Estado de São Paulo – Sabesp reports that regulator ARSESP has approved a tariff adjustment for its water and sewage services.

According to Sabesp’s preliminary review, this corresponds to a 10.6% increase in its equilibrium rate, which is a benchmark level designed to balance revenues with operating and investment needs.
The company plans to provide further clarification on the main items behind this adjustment and has noted that ARSESP also published a technical note and an Excel model detailing the calculation. Sabesp states it will keep shareholders and the market informed about any additional developments related to this rate change.
