Is It Safe to Drink Tap Water in Cabo Verde?

Cabo Verde, a beautiful island country off the west coast of Africa, is known for its stunning beaches and warm climate. But when visiting or living there, one important question often comes up: “Is it safe to drink the tap water?” This is a key concern because clean drinking water is essential for health. Let’s explore the situation in Cabo Verde in simple terms, based on facts and real data.

Why Is Water Safety a Concern in Cabo Verde?

Cabo Verde is made up of several islands with very little natural freshwater. The islands get less than 10 inches of rain each year, making fresh water very rare. Because of this, the country depends a lot on seawater desalination – a process that removes salt from seawater to make it drinkable. This is an expensive and energy-heavy process but necessary to provide water to people living in cities and tourist areas.

Treated Wastewater Reuse and Its Role in Water Safety

Cabo Verde faces severe water scarcity, and one important way to increase water availability is through the reuse of treated wastewater, especially for agriculture. Recent studies have monitored the quality of treated wastewater from municipal treatment plants on the islands. These studies found that treated wastewater generally meets safety standards for irrigation, with pollutants kept below harmful levels. This reuse helps reduce pressure on freshwater sources and supports food security, as agriculture is a key sector for the country.

However, monitoring also detected some pharmaceutical residues, such as antibiotics, in treated water. These substances can pose risks if not carefully controlled, including the development of antibiotic resistance. The government has introduced regulations (Decreto Regulamentar no. 4/2020) to ensure treated wastewater is safe for reuse and to protect public health and the environment. This approach strengthens Cabo Verde’s ability to adapt to climate change and water scarcity by making the most of available water resources.

How Is Tap Water Produced in Cabo Verde?

The main way Cabo Verde makes tap water safe is through desalination plants. These plants use advanced technology, mostly reverse osmosis, to clean seawater and turn it into fresh water. This water is then sent through pipes to homes and businesses, especially in urban areas like Praia and Mindelo. The government has been improving these systems since the early 1990s to ensure water quality meets safety standards.

Besides desalination, some water comes from groundwater or surface water sources, but these are less reliable and sometimes less safe, especially in rural areas.

Improvements in Water Infrastructure and Service Delivery

Over the past decade, Cabo Verde has made significant progress in improving water infrastructure and expanding access to piped water. The water utility Águas de Santiago has grown stronger, increasing its customer base by nearly 20% and covering its operating costs. Investments supported by government funds and international partners have helped build desalination plants and wastewater treatment facilities, especially on Santiago and Sal islands.

These efforts have led to a 43% increase in households connected to piped water and a doubling of sewer connections. While water consumption remains relatively low – about 34 liters per person per day in urban areas – these improvements mean more people have reliable access to treated water. However, challenges like drought and the COVID-19 pandemic have occasionally disrupted services, showing the need for continued investment and maintenance.

Is Tap Water Safe to Drink?

In cities and tourist areas: Tap water is generally safe to drink because it is treated carefully through desalination and purification processes. Many locals and visitors drink it without problems. For example, in Mindelo, some people drink tap water regularly, and ice made from tap water is usually safe.
In rural or remote areas: The tap water may not always be treated well or safe to drink. It’s better to boil water or use bottled water in these places to avoid getting sick.
For children: It is recommended to use bottled water to be extra safe.

What Are the Risks?

Despite improvements, some water supplies in Cabo Verde still face challenges. A study from 1989 showed that only about 10% of public water supplies met strict drinking water quality standards, and many samples contained bacteria like E. coli, which is a sign that the water had been polluted, often by human or animal waste.

E. coli is dangerous because it can cause stomach cramps, diarrhea, vomiting, and in severe cases, kidney problems. For healthy adults, the illness may last a few days, but for children, older adults, and people with weak immune systems, it can be much more serious.

Conditions sure have improved since 1989, experts say:

uneven maintenance,
old pipes,
water storage issues, and
limited monitoring in rural areas

still make some water sources unsafe.

Tap water in big cities like Praia or Mindelo may be safer due to better infrastructure, but this is not guaranteed. This shows that water quality can vary, and caution is needed, especially outside cities.

In rural areas, people often rely on wells or water delivered by trucks. These sources may not be treated or tested regularly. Plus, it is impossible to vouch for the cleanliness of these water tanks carried by trucks. “How often are the tanks washed?” no one can really tell. Meaning, even clean water can become contaminated if stored in dirty tanks or transported in unhygienic ways.

That’s why safe handling, regular testing, and proper storage are just as important as the water source itself.

While the government has taken steps to improve water safety with the help of NGOs like Aqua Maya, the risks remain real – especially outside the main cities. Travelers and even locals in rural areas need to be cautious and take extra steps to protect their health.

What Is the Government Doing?

The Cabo Verde government has made big efforts to improve water and sanitation:

Expanding desalination plants to produce more clean water.
Creating water companies on most islands to manage water supply better.
Launching social programs to help families get access to clean water and sanitation.
Reducing water loss and improving water use efficiency.

One example is Aguas de Santiago, a company working on the island of Santiago to improve water access and sanitation for nearly half the country’s population.

What Should Visitors and Residents Do?

To stay safe, here are some simple tips:

In cities, tap water is usually safe, but if you want to be extra careful, drink bottled water or boil tap water before drinking.
In rural areas, always boil or filter water before drinking.
Use bottled water for babies and young children.
Avoid drinking untreated water or using ice made from untreated water if you are unsure of its source.
Consider using water filters or purification tablets if you stay long-term or travel to remote areas.

Why Is Clean Water Important?

Clean water plays a big role in keeping people healthy, protecting the environment, and supporting tourism. In Cabo Verde, where water is limited and expensive to produce, keeping it clean is both a challenge and a priority.

When water isn’t clean, it can carry diseases like diarrhea, cholera, and other infections. These illnesses affect everyone, but they’re especially dangerous for children, pregnant women, and older adults. A single case of diarrhea can lead to serious dehydration and even death if left untreated. It also means missed school, missed work, and high medical costs that many families cannot afford.

Tourism is a big part of Cabo Verde’s economy. Visitors come for the beaches, ocean views, and fresh seafood. But if the water is polluted, it not only affects people – it also harms marine life and the country’s image as a safe destination. That’s why clean water is also a business issue.

One way Cabo Verde shows its commitment is through the Blue Flag program. This is a global award given to beaches that meet high standards for clean water, safety, and care for nature. Several beaches in Cabo Verde have already earned this certification, and more are working toward it.

In short, clean water means healthier people, stronger communities, and a better future for both locals and visitors. It’s something worth protecting every day.

Government Regulations and Emergency Measures to Ensure Water Quality

The Cabo Verde government actively regulates water quality and infrastructure to protect public health. Recent resolutions (2025) focus on increasing drinking water production, improving distribution efficiency, and maintaining sewage networks, especially in the capital Praia and other municipalities on Santiago island. These emergency and urgent measures aim to reduce breakdown risks and ensure continuous supply of safe water.

The National Water and Sanitation Agency (ANAS) has been empowered to manage contracts and funding for renewable energy projects that support water mobilization, such as solar-powered pumps. These initiatives help make water systems more sustainable and resilient to climate challenges. The government also enforces strict standards for irrigation water quality to prevent environmental damage and health risks from unsafe water reuse.

Conclusion
