Drinking Water in Thailand

Thailand is still a developing country, so when moving to Thailand there are a few things to think about and finding safe water to drink is one of those. In general, tap water in Thailand isn’t safe because of potential bacteria and pollutants in the water. The quality of tap water varies across different regions, with urban areas like Bangkok having better standards compared to rural areas. However, most organizations do not recommend drinking tap water regardless, especially for newer arrivers, due to potential health risks. Here are the easiest ways and safe places to get water for your home:

• Bottled water

• Water stations

• Water refill from school

• Water purifying/ filtration system at home

• Delivery services

• Filtered water bottles

• Water filter bottles

While boiling tap water is a common practice to kill bacteria, it does not eliminate all contaminants, such as heavy metals, raising concerns about relying solely on boiled tap water for hydration.

There are two kinds of bottled water you can buy in Thailand “drinking water” and “mineral water”. Drinking water is treated and made very safe to drink. Each brand may use a different process or filter but they all produce clean water for drinking.

Drinking water is the cheaper option. Popular brands include Chang, Singha, Crystal and supermarket own brands. Popular mineral brands include Minere, Aura and Purra. The stores own brand drinking water will run cheaper and some have their own branded mineral waters as well.

You can buy bottled water almost everywhere in Thailand. From your local supermarket, market, outlet store, convenience store, local mom and pop shops, places like Macro and more. A 6 x 1L/1,5L pack of water starts from ฿49. If they are too much for you to carry you can buy a couple of bottles at a time from ฿10 or have water delivered to your door. These last two options are especially convenient but it will cost you more money. However, the widespread use of plastic bottles raises significant environmental concerns, prompting many to consider more sustainable options.

In urban areas like Bangkok, tap water is often considered drinkable as it meets WHO standards. However, concerns about tap water quality, including the presence of harmful bacteria and other contaminants, lead many residents to prefer bottled water.

Thailand bottled water is affordable and widely available, typically costing around 15 Baht for 1.5 litres.

Drinking unclean tap water can lead to serious health issues such as cholera and typhus. The water quality varies significantly across different regions, with rural areas posing a higher risk due to outdated infrastructure and less stringent treatment processes. Therefore, it is advisable to opt for bottled water to ensure safety.

Safety of Drinking Water in Thailand

Drinking water in Thailand can be a concern for tourists and locals alike. While tap water is not considered safe to drink in most areas, there are ways to ensure access to clean drinking water. Bottled water is widely available and inexpensive, making it a popular choice for many. However, it’s essential to check the seal before drinking to avoid contamination. Additionally, using a filtered water bottle or a water filter at home can also provide a safe and reliable source of drinking water. By taking these precautions, you can enjoy your time in Thailand without worrying about waterborne illnesses.

Water Stations

Water stations are everywhere in Thailand. As it gets very warm in the warmer seasons, making sure everyone has enough water and access to it is a must. There are different companies, so if you like one company more than another you can use that specific water station. Water stations are very affordable and straight-forward to use even for foreign teachers.

Step 1: Bring your refillable bottle to your chosen station

Step 2: Place your bottle in the station, lining it up with the nozzle in the machine.

Step 3: Put your coin(s) in for your desired amount of water and push the green button.

Step 4: When your bottle is filled, take your water, close the lid and there you have it!

One point I will add is about the maintenance of each machine affecting the quality of the water. In some areas they may change the purifier less frequently or less frequently. Some machines shut down after a certain amount of water has been purified so someone will come out to do maintenance on it. Whether it gets another filter change is dependent from company to company and the standards of practice. Ensuring proper maintenance is crucial for maintaining good water quality and providing safe water. Some people use the stations then boil or purify it again at home. So even if it’s not as purified as it should be, you can still use the station for easy access to water and repurify.

In your condo, however, there will be higher safety standard and maintenance for the water purifying and filtration systems. And if you have any worries at all you can request a timesheet of when they are done to put your mind at ease.

Filtered Water From School

If you have a filtered water station or dispenser at your school, I highly suggest you use it. You can bring 1-2 x 1.5L bottles, fill them up before you leave and you’ll have your daily amount of water. Using filtered water bottles is a convenient option to ensure safe drinking water. On the weekends you may need to buy a couple of bottles here and there or plan ahead and fill up enough for the weekend. Of course, you will need empty bottles to take with you to school but this is a cost-effective way to get water. If you feel uneasy about this method you can always do 50/50 which will still cut-down on your water expenses.

Water Quality Filtration System at home

After a few months or years, you might consider getting a water filter for your home. There are 2 easy options and one expensive option. Additionally, for those who are always on the go, water filter bottles serve as an eco-friendly and effective solution for ensuring safe drinking water, reducing reliance on single-use plastics.

Option 1: Over-the-tap Filter

Option 2: Britta-Style Filter

Option 3: Installing Filtration systems in your home

Option 1 is a user-friendly filter that you can attach straight onto your taps. You can purchase these in stores or online. Full price ones can run around ฿2000-4000 but on sale you can get a Philips water purifier for ฿899. You could also get a portable water bottle with purifier build in to it and purify all water as and when you need it.

Option 2 would be using a Britta- style filter (which are a little pricy). They are free standing, jug style containers with an in build purifying filter that you replace after a designated amount of time. A Pure brand one costs around ฿790 online and replacement filters cost around ฿190. More expensive models look more akin to a coffee machine that purify water.

Option 3 are for those who maybe want to stay long term in their own property. Installing a water purifying system for your whole house can make all water from your tap to you shower cleaner and less harsh. Filtering out sand, dirt and dust whilst also purifying water for drinking, cooking and cleaning.

Bottled Water Delivery Service

Last but not least are the delivery services. You can get a membership and download apps with a supermarket or convenience store that deliver. Alternatively, you can sign-up to online shopping services (Shopee, Lazada etc.) or use transportation apps (Grab, Bolt, LineMan, etc.) and have all the water you need and deliver it to your door. You can even set up scheduled or recurring orders on some platforms.

Another delivery option is going in store and asking them to deliver it. This will require you to speak some Thai or use a translation app and having your address and a Thai number to hand. Some may still ask you to download their app if they have one. You will also need a membership so bring your ID to register.

This might be one of the most convenient ways to get water but is usually more expensive than getting it yourself. You can decide if the costs outweigh cons.

Using Tap Water for Personal Hygiene

While tap water is not recommended for drinking, it is generally safe to use for personal hygiene purposes such as brushing teeth, washing face, and showering. However, it’s crucial to avoid swallowing tap water while brushing teeth or washing face, as this can still pose a risk of waterborne illnesses. If you have a sensitive stomach or are not used to the local water supply, it’s best to use bottled water for brushing teeth and washing face. This small step can help you avoid any potential health issues and ensure a more comfortable stay in Thailand.

Ice and Cold Beverages

Ice in Thailand is generally safe to consume, as it is made from treated water. However, it’s essential to check the source of the ice, as some street vendors may use untreated water. When consuming cold beverages, it’s best to opt for drinks made with bottled water or filtered water to minimize the risk of waterborne illnesses. By being mindful of the source of your ice and beverages, you can enjoy refreshing drinks without compromising your health.

Tips for Staying Safe

To stay safe while drinking water in Thailand, follow these tips:

• Always drink bottled water or filtered water

• Avoid drinking tap water, even if it’s boiled

• Check the seal of bottled water before drinking

• Avoid swallowing tap water while brushing teeth or washing face

What to Do if You Get Sick

If you suspect you’ve consumed contaminated water and are experiencing symptoms such as diarrhea, stomach cramps, or vomiting, seek medical attention immediately. In Thailand, pharmacies are widely available and offer over-the-counter remedies like rehydration salts (electrolytes) and anti-diarrhea medication. If symptoms persist or worsen, it’s advisable to visit a hospital or clinic, as waterborne illnesses like giardia or amoebic dysentery can require specific treatments. Taking prompt action can help you recover quickly and get back to enjoying your time in Thailand.
