However, distribution issues like old pipes and contamination risks mean some locals and tourists avoid drinking tap water directly.

Source of Water in Rio de Janeiro, Brazil

Rio de Janeiro's tap water mainly comes from surface water sources, including reservoirs like Guandu and Santa Cruz. These supply the city’s water treatment plants.

The Guandu system is the largest, providing over 70% of the metropolitan area's water. It sources water from the Paraíba do Sul River basin.

Other smaller sources include the Ribeirão das Lajes and Pau da Fome reservoirs. These supplement the primary supply and support water distribution in the city.

Rio de Janeiro Drinking Fountains

Public drinking fountains in Rio de Janeiro may not consistently provide safe water due to potential contamination and maintenance issues.

Water quality at these fountains is variable, and many locals avoid using them for drinking without additional filtration or treatment.

For safety, it is recommended to use bottled or properly filtered water rather than relying on public fountains for drinking.
