The Centers for Disease Control and Prevention (CDC) lists six Asian countries — Brunei, Hong Kong, Israel, Japan, Singapore, and South Korea — as having safe tap water.
This means if you’re visiting Bali, you mustn’t drink tap water, as it’s unsafe.
Unsafe tap water contains impurities that can pose health risks.
While the local government works hard to keep the water clean, the quality can vary across the island.
To help you stay hydrated safely in Bali, we’re sharing practical tips on everything, from alternatives to tap water to maintaining drinking safety at bars and restaurants, so you can enjoy your time in Bali.
Understanding Tap Water Sources in Bali
Rivers and Lakes
Bali’s tap water mostly comes from rivers, lakes, and reservoirs, like the Ayung, Petanu, Unda rivers, and Lake Batur.
PDAM, a state-owned entity, manages water from these sources. However, the quality of this treatment can differ across areas because of the differences in infrastructure and how well local PDAM facilities are maintained.

Groundwater
Many villas and hotels not connected to the PDAM grid rely on groundwater from wells. The quality of this well water varies by location. More crowded areas often have more contamination.
Additionally, deep well pumps used in these places might not have proper filtration. So, impurities like sand enter into the tap water.
Rainwater Harvesting
In some rural areas with limited access to treated water sources, rainwater harvesting is used to meet water needs.
Why Tap Water in Bali Is Not Safe To Drink
- Inconsistent Treatment Quality:
One or more stages of water treatment (sedimentation, filtration, and disinfection) might not be properly performed. So water may still contain pollutants.
- Old, damaged or Leaking Pipes:
When pipes are outdated or damaged, they can let in contaminants from the surrounding environment.
Leaking pipes allow soil, chemicals or other pollutants into the water supply. Plus, deterioration of infrastructure can affect the water quality as it travels from the treatment facility to your tap.

- Heavy Rain Runoff:
During heavy rains, water from the surface, including dirt, chemicals, debris, and pollutants from streets and land, can flow into water sources. This runoff can increase the level of contaminants in the water. Even though additional filtration is used to clean the water, heavy rain can overwhelm the system and bring in excess pollutants.
- Issues With Well Water:
Groundwater might be polluted with waste or chemicals. The deep well pumps used to extract this water may not have effective filtration. Impurities, like sand, can enter the water supply.
- Chemical Contaminants:
To get rid of pesticides or industrial chemicals, special treatment methods are needed, but these methods aren’t always used.
How Do Bali Locals Have Safe Drinking Water?
Many Balinese locals rely on delivered filtered water, like Aqua or Balian Natural Mineral Water. This water is purified or collected from natural springs and provided in large bottles or dispensers. These large refillable water containers can be found all over the island in local mini marts and stores.
Another popular solution locals use is to boil water which provides a simple and reliable way to ensure harmful bacteria, viruses, and parasites in water are killed.
Some Balinese use natural materials like sand, charcoal, or gravel to filter their water alongside boiling for an additional layer of purification. Sand filters trap larger particles. Charcoal absorbs contaminants and chemicals.
After purifying the water, locals store water in traditional containers, like clay pots and glass bottles. Clay has natural cooling properties, and glass is easy to clean.
How Can Tourists Have Safe Drinking Water?
Bottled water is the safest option for tourists in Bali.
It is treated and filtered in controlled environments before being sealed. It consistently meets high cleanliness and safety standards.
Where To Buy Bottled Water Brands in Bali
- Supermarkets, like Carrefour, Bali Deli, and Bintang Supermarket
- Convenience Stores, like Indomaret and Alfamart
- Hotels and restaurants
The Challenge of Using Bottled Water in Bali
During the wet season, rain and storms carry plastic waste from land to the sea. This affects marine life and the beaches’ beauty.
Locals and the government are working hard to clean beaches. But these efforts take time and are not sufficient.
The alternative is using reusable bottles.

Reusable Water Bottles in Bali
You can choose from these brands — S’well, Hydro Flask, LifeStraw Go, and Klean Kanteen. You can find these bottles in upscale stores, speciality shops, and online platforms that deliver to Bali.
Nearly all of them are durable, well-insulated, and easy to carry. Some come in different sizes and colours. LifeStraw Go includes a built-in filter.
Benefits of Reusable Water Bottles
- Reduce Plastic Waste:
You cut down on single-use plastic bottles.
- Save Money:
Reusable bottles reduce your need to buy bottled water.
- Are Convenient to Carry:
Reusable bottles are easy to carry and fit well in backpack pockets or cup holders.
- Have Built-in Filters:
Some reusable bottles have filters that clean the water.
- Reduce the Need to Purchase Water:
Having a reusable bottle means you can refill it at various sources. This reduces the need to constantly buy bottled water.
Water Refill Stations and Apps
Usually, they are located in cafés, restaurants and shops in Ubud, Seminyak, and Canggu. Apps, like Refill My Bottle, help find the location of refill stations. They also help you know which locations offer free or paid refills.

Bottled Drinks in Bali
Commercially bottled drinks, like sodas and juices, are safe to consume in Bali. These drinks undergo rigorous quality checks to ensure they meet safety standards. Make sure the bottle seal is intact.
Tips on Checking Seals and Expiry Dates
- Look for any signs of damage to the bottle or cap
- Check the expiry date on the bottle to ensure the drink is still within its shelf life.
- Before drinking, gently shake the bottle and check for any sediment or strange smells. These could be signs of spoilage.

Are Cocktails Safe to Drink in Bali?
Generally, cocktails are safe to drink in Bali. You should stick to drinking cocktails at reputable bars like Pinstripe Bar. We recommend checking online reviews before you visit and avoiding empty or run down looking bars, clubs or restaurants.
You should confirm with the bartender what ingredients are in your cocktail before ordering. Some bars use a local spirit called Arak which is generally safe to drink however some travellers may want to avoid drinking it.
Some may have concerns over methanol poisoning from drinking cocktails, however in reality this is a rare occurrence.
Drinking Safety in Restaurants and Bars in Bali
There are some simple practices you can follow when drinking in bars and restaurants in Bali.
Tips for Selecting Hygienic Bars and Restaurants
- Observe Cleanliness:
Pay attention to the overall appearance of the bar or restaurant. Check if:
- Staff are wearing clean uniforms and practising good personal hygiene.
- Floors are spotless.
- The tables are clean.
- Utensils are spotlessly clean.
- The bathroom has essentials, like soap and paper towels.
- Ask Locals:
Talk to locals or other travellers for their opinions on where to go. They often know which places are well-regarded for their cleanliness and safety.
Check reviews on platforms like Google Maps, TripAdvisor, or local forums. Look for comments on safety and cleanliness at the facility. Check for certifications indicating adherence to local health standards.
- Notice the Crowds:
A busy bar or restaurant has a high turnover of customers. This means that food and drink ingredients are fresher; they are used more quickly and replenished regularly.
Establishments that are popular and well-frequented maintain higher hygiene standards to keep their reputation intact.
To stay safe when drinking at Bali bars and restaurants, remember to choose trusted places and opt for eating at top rated venues.

Ice Cubes in Bali Drinks
Be cautious with ice in Bali drinks. Ensure it’s made from filtered water or avoid it altogether.
Risks Associated with Ice in Drinks
- Potential Contamination:
Ice made from unfiltered tap water will carry the same contaminants. The freezing process does not eliminate contaminants. So, consuming drinks with contaminated ice can be risky to health when the ice melts in your drink. You can get gastrointestinal issues or other illnesses.
- Storage and Handling Issues:
Even if the water used to make ice is clean, ice can become contaminated if it is left out in unsanitary conditions or handled with dirty utensils or hands. Moreover, ice stored in old or poorly cleaned containers can pick up bacteria and other harmful substances.
- Local Practices:
In some areas, ice hygiene practices might not meet the standards you’re used to. Ice may be produced in bulk and stored in unsanitary places. It might also be transported in unsafe conditions.
Tips To Check if Ice Cubes Are Not Contaminated
- Ask the restaurant or bar’s staff.
- Check online reviews or ask for recommendations from locals about bars and restaurants that use filtered water for ice.
- Check the ice before it’s added to your drink. It must be clear and free of any particles.
Tips for Enjoying Drinks Without Ice Cubes
- Opt for bottled or canned drinks. They are sealed and come pre-chilled.
- Use substitutes, like chilled fruit or frozen berries.
- Use refreezable plastic ice cubes.

Bali Drinking Water Etiquette: Cultural Considerations
- Respect Local Customs:
When you visit traditional Balinese homes or temples, locals may offer you water. If you’re unsure about its safety, ask politely about it. Avoid causing any fuss, as it could seem like locals are not careful about offering safe drinking water. Ask locals for tips on safe drinking water and trustworthy sources. They can direct you to reliable places to buy bottled water or refill your bottle. They know which shops or cafes prioritise water quality.
- Avoid Asking for Ice in Rural Areas:
In remote or rural areas, ice might not always be made from filtered water. Avoid asking for ice in these locations or politely confirm its safety before accepting it.
- Use Reusable Bottles:
Carrying a reusable bottle shows your respect for the environment. It aligns with local environmental practices and Balinese culture. Locals will appreciate your effort to reduce waste and support their values.
- Be Considerate of Local Water Resources:
Bali has limited water. It’s important to use water carefully and avoid waste to help ensure there’s enough water for everyone.
