The regulation of public services in the current model was developed in the country during the 1990s, particularly after the Concessions Law (Federal Law Nº 8,987/1995), when the country’s first regulatory agencies were founded. With the enactment of Federal Law Nº 11,445, in 2007, also known as the legal framework for basic sanitation , which establishes the national guidelines for basic sanitation, the sector has undergone institutional change and, within this context, by means of Supplementary State Law Nº 1,025/2007, ARSESP – São Paulo State Public Services Regulatory Agency was created with the purpose of regulating, supervision and inspecting the services offered and delegated by state and municipal authorities under the terms of Federal Law Nº 11,107/2005.
In June 2020, Federal Law Nº 14,026 was enacted, which updated the legal framework for basic sanitation and assigned to the National Water and Basic Sanitation Agency (ANA) the power to edit reference standards on sanitation services. The Law also prohibits services to be provided through program contracts.
Remuneration for water and sewage services is done through tariffs set by ARSESP during ordinary four-year revision, or extraordinary revision, and annual tariff adjustments. While tariff revision address the recomposition of tariffs so they can cover operational costs, maintenance and expansion considering an efficient regime for expenses and a prudence regime for investments, according to the rules determined by the ARSESP, the readjustments are intended to maintain the tariff level by applying the inflation (IPCA) variation, deducting the X Factor, in order to share efficiency with users, and is also adjusted by the Service Quality Factor (IGQ), which can be positive, null, or negative according to the results obtained versus the goals established by Sabesp and approved by ARSESP.
SABESP’s current tariff structure consists of tariffs according to categories of use, residential, commercial, industrial and public, and within these categories there are special tariffs for users with less purchasing power, such as the social tariff and favelas (only in the Metropolitan Region of São Paulo – SPMR), for social assistance entities and public administration entities that sign a contract with SABESP for the implementation of the Rational Use of Water Program – PURA. In addition, there are also tariffs for large commercial and industrial consumers, and for wholesale supply of water and sewage treatment to municipalities that operate their water distribution and sewage collection systems in the RMSP.
