The city of Piracicaba in São Paulo has come under scrutiny as it dropped 11 positions to 35th in the national sanitation ranking published by the Trata Brasil Institute for 2026. Previously holding the 24th spot, the decline has raised concerns about the city's management of water and sanitation services. This fall is attributed primarily to a decrease in water service provision as well as a notable reduction in total investment per capita, now down by approximately R$ 80 compared to the prior assessment.

In their official response, the Municipal Water and Sewage Service (Semae) highlighted ongoing investments aimed at improving the sanitation sector, suggesting that the current administration is taking steps to address the issues identified in the ranking. The report details monetary allocations toward enhancing infrastructure and increasing service reliability. However, the evident drop in the ranking has sparked a discussion about the effectiveness of these initiatives so far and the urgent need for better resource management.

The ranking's release has also prompted reactions from local officials and residents, with an emphasis on the pressing need for improved water quality and access. The city is now facing pressure not only to elevate its ranking but also to enhance the living conditions of its residents by guaranteeing consistent access to clean water and adequate sanitation services. As the municipal government responds to these challenges, the future of Piracicaba's sanitation services will be closely monitored by both citizens and stakeholders in the region.
