Can You Drink Tap Water in Buenos Aires?

Tap water in Buenos Aires is generally safe to drink. AySA supplies and treats water for the city and much of the metropolitan area, with the Río de la Plata serving as the principal source. The water is disinfected and monitored before entering the distribution network.

Many residents drink tap water directly, while others use filters because the water can have a noticeable chlorine taste. The main reason for extra caution is the plumbing inside older apartment buildings rather than the municipal supply itself. Historic properties may have ageing pipes or private storage tanks that affect taste and appearance.

In Palermo, Recoleta, San Telmo, Puerto Madero, Microcentro and other central visitor districts, tap water in reputable hotels and modern apartments is normally safe. If the water is clear and has no unusual odour beyond mild chlorine, it can generally be consumed. Ask the host about plumbing or use a filter in a very old building.

The water is safe for drinking, brushing teeth, cooking and making ice in maintained buildings. Restaurants commonly serve tap water when requested, although bottled still or sparkling water is often presented by default.

Bottled water is available everywhere but is not required for health reasons in central Buenos Aires. Villavicencio and Eco de los Andes are common local brands. Carrying a reusable bottle and refilling at a reliable tap is practical.
