Is Tap Water Safe to Drink in Cuba?
No, tap water in Cuba is not safe to drink anywhere in the country, including Havana. Bottled or boiled water is essential due to aging infrastructure and inconsistent treatment.
Water Source
Cuba's water infrastructure is significantly under-invested, with many pipes over 50 years old and frequent water main breaks that let contamination into the supply.
Contaminants & Concerns
Bacterial contamination from broken and leaking pipes is widespread; supply is also intermittent in many areas, requiring rooftop storage tanks that can further affect water quality.
Regional Variations
Not safe anywhere, including Havana, Varadero, and Trinidad. Even resort areas typically supply bottled water for this reason.
Water Hardness
Not centrally published; not relevant given universal bottled/boiled use..
Do Locals Drink Tap Water?
