Drinking water in the Maldives: is tap water safe?

The Maldives is a country of low coral islands with no rivers, lakes or springs. Fresh water comes from three places: the sea, the sky and a thin layer under the ground.

• Desalinated seawater. Reverse osmosis plants turn seawater into fresh water. This is what comes out of the taps in Malé and on a growing number of other islands.
• Rainwater. For generations, families have collected rain from their roofs into household tanks. On many outer islands it is still the main drinking water.
• Groundwater. Each island sits on a small “lens” of fresh water floating on top of seawater in the sand and coral below. People draw on it through wells for washing, gardens and toilets.

Bottled water fills the gaps. The Maldives Bureau of Statistics Household Census 2022 found that bottled water is the most common source of drinking water across the country, while in the atolls many households still drink rainwater from their own tanks.

The capital area gets its piped water from the state-owned Malé Water and Sewerage Company (MWSC), which runs desalination plants for Malé and the islands around it. In March 2019 the then environment minister described the water as well above WHO standards, and officials from the Environmental Protection Agency and the Maldives Food and Drug Authority said it is tested at several stages before it reaches homes. The Utility Regulatory Authority is the body responsible for water quality standards.

Even so, many people in Malé still choose bottled water, partly from habit and partly because water can pick up tastes or problems from building tanks and pipes. As a visitor, a sensible approach is:

• Treat tap water in a hotel or apartment in Malé or Hulhumalé as fine for brushing your teeth.
• Drink bottled water, or filtered water your accommodation provides, unless your host tells you the tap water is drinkable.
• Carry a refillable bottle. In 2022 the Housing Development Corporation agreed with MWSC to provide drinking water points in some public spaces in Hulhumalé (as reported).

Outside Malé, piped water is run by different bodies. FENAKA, the state-owned utility for the outer islands, said in January 2025 that it provides water and sewerage services on 107 islands. Some islands have their own council-run or community systems. Others still rely mainly on rainwater tanks.

That means the answer to “is the tap water safe?” depends on the island and the building. Things to know:

• Taps may be desalinated, rainwater or groundwater. Researchers found that most households use well water for washing and toilets, so in some buildings the shower runs on it and can taste slightly salty.
• Groundwater is not for drinking. A 2020 study by Ministry of Environment and UNDP researchers, covering 45 inhabited islands, found that residents saw groundwater as unfit to drink, and most islands reported some salinity. Septic tanks and soak pits close to wells are a known source of contamination.
• Rainwater needs care. Rain stored in clean, covered tanks is the traditional drinking water, but after heavy rain or floods the Health Protection Agency (HPA) has advised people to boil rainwater or use bottled water for drinking and cooking.
• Dry-season shortages happen. Late in the dry northeast monsoon, some islands run low on rainwater, and water is sometimes shipped in. It rarely affects visitors, but it is a good reason to use water carefully. Read more in our monsoons guide.

What guesthouses usually provide

Most guesthouses on local islands provide drinking water for guests, either as bottles in the room or from a filter or dispenser where you can refill a bottle. Ask when you arrive:

• Is the tap water desalinated, rainwater or well water?
• Is there a filtered water point I can use for refills?
• Is the water in the kettle and coffee machine from the drinking supply?

Advice from public health bodies such as the US Centers for Disease Control and Prevention (CDC) is simple: where you are unsure of the water, brush your teeth with bottled or treated water, avoid swallowing shower water, and skip ice unless you know it is made from safe water. Boiling, filtering and chemical treatment are the standard ways to make water safe.

In practice, in the Maldives:

• Ice: ask how it is made. If you are unsure, order drinks without it.
• Brushing your teeth with desalinated tap water is generally fine. Use bottled or filtered water if the tap is well water or you do not know.
• Fresh juice and salads are widely eaten. If you have a sensitive stomach, start slowly in your first few days.
• King coconut water (*kurumba*) straight from the nut is clean, safe and very refreshing. See the coconut palm guide.

The Maldives is hot all year, with air temperatures around 30–31°C and strong sun. You will need more water than you think, especially on boat trips, snorkelling days and long walks.

• Drink steadily through the day rather than all at once.
• Take water on every excursion. Boat crews often carry drinking water, but bring your own bottle anyway.
• Watch for headaches, dizziness and dark urine, all early signs of dehydration.

Bottled water comes at a cost to small islands. Every empty bottle has to be shipped away or dealt with on an island with very limited space for rubbish. Officials said in 2019 that more than 280,000 plastic water bottles were used every day in Malé alone.

The government has a list of single-use plastics to be phased out, and plastic water bottles are on it. The dates have moved several times. In December 2025 the President’s Office announced a ban on importing and producing 500 ml to 1 litre plastic water bottles from 1 December 2027. In September 2026 that was deferred again, to 1 December 2029, with a sales ban from 1 June 2030 (as reported by Edition). The government said some islands still lack a proper water system, so people depend on bottled water.

What you can do:

• Bring a refillable bottle, ideally insulated to keep water cool.
• Ask your guesthouse for refills from its filter or dispenser.
• Buy the largest bottles you can and decant them, rather than many small ones.
• Take your empties back to your guesthouse rather than leaving them on beaches or sandbanks.

Dhiffushi is a good example of how things work on a local island. It has a piped water and sewerage network serving around 300 households, opened in recent years (as reported by PSM). Visitors are advised to drink bottled or filtered water, and most guesthouses provide it. Our Dhiffushi trip planner covers health, money and getting around, and the Dhiffushi packing list suggests bringing a refillable bottle.
