When travelling to Bangkok, one of the common questions visitors ask is whether it is safe to drink the tap water. In many places around the world, tap water is considered perfectly safe to drink, but in Bangkok things are a little different. In this article we look at the reality of drinking tap water in the city, the safety concerns, and an eco-friendly, sustainable alternative for hydration while visiting or living in Bangkok. If you are searching the web for Can you drink tap water in Thailand?, this article will help you understand the situation.

Is Bangkok's tap water safe to drink?

The short answer is: it is not recommended. Although tap water in Bangkok is treated at the plant with filtration and chlorination, it is not intended to be drunk straight from the tap. Treatment at the plant does not guarantee what arrives at your glass after the water has travelled through the city's pipes and a building's tanks, where bacteria, chemical residues and metals can enter.

In fact, most locals do not drink tap water in Bangkok. City dwellers drink bottled water or filtered water from dispensers, by and large. The main reason is concern about the quality of tap water, which can be surprising for someone used to drinking potable water straight from the tap.

The Safety Reasons

There are several reasons why tap water in Bangkok is not considered safe to drink in many situations.

1. Ageing pipes

Although the water is treated, conditions vary across the city. Some areas have older pipes, which means that once the water leaves the plant it can pick up contamination from the ageing network. Sediment, rust and metals can collect in the water, which is not safe enough to drink without treatment.

2. Chlorine and chemical residues

Chlorine is added during treatment to deal with pathogens, and it does its job. But its taste and smell are noticeable, and chlorine by-products are something many people prefer not to drink day after day.

3. Bacteriological risk

There is a higher chance of bacterial contamination where the plumbing is poor or the pipes are old, or where supply is intermittent. This is more likely in older buildings or hotels that may not have the best plumbing infrastructure or well-maintained roof tanks.

4. Pollution and wastewater

Bangkok, like many big cities, suffers from pollution. While treated water is distributed across the city, environmental contamination from industrial waste or untreated sewage can affect the raw water that the plants have to deal with.

What the water carries varies by district, season and building, so treatment is specified for a site, not for a city. Our guide to tap water in Thailand details what the mains can carry and the stage that deals with each item.

Bottled Water: First Choice

Most people in Bangkok do not drink their tap water, and bottled water is widely used across the city by residents and visitors alike. However, environmental issues have always surrounded bottled water. Plastic bottles make up a large share of the pollution in a city like Bangkok, which already has huge amounts of plastic waste to deal with.

Plastic bottles take ages to decompose and add to an environmental problem that keeps growing. Every purchase by residents and visitors keeps the plastic cycle turning, at a cost to the environment and to living things. Bottled water also moves the problem rather than solving it, since its quality depends on the bottler and on how the bottle was stored.

Minairal Mineral Water Dispensers

Minairal is a Thai company offering a practical answer to hydration in Bangkok and beyond. Its mineral water dispensers produce fresh, sustainable drinking water on site, with zero plastic bottles. Mineral-rich water goes straight from the system into your glass or bottle.

It replaces plastic bottles with a clean, responsible alternative, and it is easy and reliable at the same time.

How it works

Two ranges cover Bangkok's situations. The Pure range connects to the existing water line and filters it through five-stage reverse osmosis at 0.0001 micron, which removes heavy metals and dissolved contaminants, then restores calcium, magnesium, potassium and sodium through a Biocera mineral filter, with continuous UV-C sterilisation and hot 90°C and cold 4°C dispensing. The Air range needs no water connection at all: it condenses humidity from the air, treats it and remineralises it, producing 13 to 30 litres a day on average depending on the model.

Either way, the water is checked: TDS and pH at each maintenance visit, and under the business service plan an independent ISO 17025 laboratory test once a year. Whether it is your household or a business in Bangkok, there is a source of clean water on site, with no bottled water to buy and no deliveries to wait for.

Benefits of a Mineral Water Dispenser

The dispenser is an investment that pays for itself over time by replacing bottled water purchases, which makes it a sound choice for businesses or families that drink a lot of bottled water.

Water from our dispensers is not only filtered but also remineralised, for a fresh, crisp taste with an alkaline pH of 8.5 and above and 40 to 80 ppm of total dissolved solids, a clear step up from chlorinated tap water.

Water Quality

Mineral-rich drinking water, filtered and checked, is a sound basis for daily hydration. The treatment sequence and the checks are described on our water quality page.
