The Sabesp privatisation has made your water and sewer bill 15% lower than it would be if the company had stayed in state hands. That is the claim made by Governor Tarcísio de Freitas during a debate on 9 August 2026. He said the discount is written into the law and into the contract. It reshaped Brazil’s largest water utility, and it matters for every household and investor in the region.
Sabesp privatisation: The 15% Claim Explained
Tarcísio didn’t say there was a simple 15% cut from old bills. He described a comparison: tariffs are 15% below the level they would have reached under a public Sabesp.
The news site Poder360 reported his exact words on 9 August 2026. SpaceMoney says the contract set a lower adjustment path than if the company had stayed state-owned.
The exact formula behind the 15% figure hasn’t been fully released in public documents. But the governor insists it’s a legal and contractual promise.

How the Privatisation Worked
The privatisation closed in July 2024. The state sold 32% of its shares in a secondary offering, raising R$14.8 billion (US$2.9 billion).
The buyer was Equatorial Energia, which took control of Sabesp. After the deal, the state’s stake dropped from 50.8% to about 18.3%, though that number comes from market reports rather than an official filing.
The company still operates under the Sabesp name, with Carlos Augusto Leone Piani as president.
Investments and Universalisation
The state government says Sabesp is expected to invest R$70 billion (US$13.7 billion) under the post-privatisation contract. The goal is to bring water and sewer service to everyone in all 375 municipalities served by the company by 2029.
Progress is already visible. The news outlet Broadcast reported on 14 July 2026 that Sabesp invested R$15.2 billion (US$3.0 billion) in infrastructure in 2025.
That’s a 120% jump from R$6.9 billion (US$1.4 billion) in 2024, the year before privatisation. The longer-term plan goes further.
Money Times reports that Sabesp foresees about R$200 billion (US$39.2 billion) in investments by 2060. This covers expanding water supply and sewage collection and treatment across the state.
What It Means for Residents and Investors
For households, the 15% lower tariff is a real benefit, even if it’s a comparison with a made-up scenario. For investors, the privatisation opened a new chapter: a private operator with clear expansion goals.
The company has also been returning cash to cities, having passed R$3.6 billion (US$705 million) to 220 municipalities since July 2024. But there are risks.
The merger with EMAE, a state power generator, has drawn lawsuits from minority shareholders who question the terms. The São Paulo public prosecutor is also probing both privatisations.
If you hold shares in Sabesp or trade on the Brazilian stock exchange, keep an eye on these disputes.
