Is Tap Water Safe to Drink in Cabo Verde?

Praia on Santiago island and Mindelo on São Vicente rely heavily on seawater desalination plants due to the archipelago's scarce rainfall and limited freshwater aquifers. Smaller islands such as Fogo and Santo Antão depend more on a mix of desalination, groundwater wells, and rainwater catchment, with less consistent treatment monitoring.

Desalinated water itself is typically low in bacterial and mineral contaminants at the point of production, but aging municipal pipes on some islands can introduce sediment or bacterial regrowth before water reaches taps. Groundwater wells on smaller islands can show elevated salinity from seawater intrusion, particularly during dry periods.

Praia and Mindelo have the most modern desalination and distribution infrastructure and generally the most reliable water quality in the country. Outer islands like Brava, Maio, and parts of Santo Antão have less consistent supply and monitoring, making bottled water the more prudent choice there.

Desalinated water in Praia and Mindelo is very soft, generally under 50 mg/L, while groundwater wells on smaller islands with saline intrusion can run considerably harder, sometimes above 250 mg/L..

Many Cabo Verdean urban residents drink tap water without issue, but bottled water remains popular and widely available, especially among visitors and on the outer islands.

• •Bottled water is recommended on smaller outer islands
• •Tap water in Praia and Mindelo is usually fine for brushing teeth but bottled is safer for drinking
• •Ask your accommodation whether their water is desalinated municipal supply or a private well
• •Carry a reusable bottle with a filter for extended island-hopping trips

• •Prefer bottled water on outer islands with less developed infrastructure
• •Check with hosts about water source before drinking directly from the tap
