Source of Water in Curitiba, Brazil
Tap water in Curitiba comes mainly from surface water in the Alto Iguaçu basin, including the Iraí, Passaúna, Piraquara and Miringuava systems. These reservoirs and rivers are located in Curitiba and neighboring municipalities in the metropolitan region.
Sanepar collects and treats this water at treatment plants before distributing it through Curitiba’s municipal water network. Treatment removes suspended matter and microorganisms, and the water is disinfected before reaching homes and businesses.
Curitiba Drinking Fountains
Public drinking fountains in Curitiba generally use treated municipal water and are safe when they are clean, well maintained, and clearly marked as potable. Water quality is regulated under Brazilian drinking water standards.
Avoid fountains that lack potable-water signage, show visible dirt or damage, or have stagnant water around the outlet. When maintenance is uncertain, use sealed bottled water instead.
