Is It Safe to Drink Tap Water in Malaysia?

Tap water in Malaysia is suitable for individuals’ consumption only when taken from trusted water treatment facilities. Government and commercial organisations such as Air Selangor are responsible for carrying out sufficient tests to ensure that Malaysian water consumption quality is adequately handled. Most of the time, the water supply in Malaysia will undergo testing to successfully fulfill the requirements set by international organisations, such as the World Health Organisation.

Is Malaysia’s Water Clean?

The Ministry of Health (MOH) in Malaysia established guidelines for water treatment, including adding chlorine to the water to eliminate microorganisms. This ensures that impurities and pathogens are removed from the water before the public consumes it. Even though chlorine is added to the water and effectively kills bacteria, the quantities added during water treatment are not harmful to people. These chlorine concentrations are much lower than necessary to make people sick.

It may not be safe to drink water right from the tap. This is reinforced by the fact that different areas in Malaysia may not have a good piping system, which might directly affect the water being supplied to the area. Drinking water thoroughly purified and filtered from bacterial, chemical, and physical impurities is best. Taking the extra precaution of purifying and filtering your water supply will ensure that your drinking water will be safe and healthy.

What is in tap water that is bad?

Tap water contains many impurities and contaminants that are not safe to be consumed by the human body. These harmful substances can damage the body if they enter our system, as they can cause us to contract deadly diseases such as typhoid, dysentery, and cholera.

Contaminants and impurities found in unfiltered tap water can be physical, chemical, or bacterial. This includes viruses, bacteria, minerals, lead, copper, fungi, parasitic worms, organic waste, pesticides, and many more.

How do you make sure you are drinking clean water?

Water kit analysis

It is crucial to take steps to ensure you are drinking water that is safe, clean, and without any harmful substances to prevent yourself from getting sick and contracting severe diseases. One way you can ensure the safety of your drinking water is by using a water analysis kit at home.

A water analysis kit will contain a testing strip that will change colour to indicate whether the water is safe to drink. Another way is to contact the water treatment plant to inquire about their water quality information.

Yet, the most common and easiest step is to drink filtered or purified water. This is because purified and filtered water goes through filters that remove impurities and contaminants before you can drink it.

Filtered water

Water that has undergone filtering using water treatment techniques is referred to as filtered water. Water can be filtered using various methods, including reverse osmosis, activated carbon, ion exchange, distillation, etc. Filtered water may successfully remove dangerous impurities and contaminants from the water while reducing the smell of tap water to make it more pleasant to drink. The home and office water purifier will filter your water to ensure that all the harmful impurities are removed so you can safely consume your water without any worries.

Water purifier

Purified water must undergo several chemical treatments and mechanical filtrations to create clean, drinkable water that everyone can ingest daily. Water’s purification process includes coagulation, sedimentation, filtration, and distillation to ensure that the water does not harbour hazardous substances, such as soil particles, heavy metals, mineral residues, and chemicals. Due to filters like the nano-positive membrane, sediment filter, and activated carbon filter that successfully remove significant pollutants, undesired chemicals, and viruses from the water, a water purifier can effectively purify the water.


Drinking a healthy water supply will help your body regulate its temperature to an average level, protect sensitive tissues, and eliminate waste through perspiration, bowel movements, and urination. You should always drink water free from impurities, as contaminants can destroy your body and render you ill.

We highly recommend using a water purifier in Malaysia to purify your water from all physical, chemical and bacterial impurities. This is to ensure the water we consume will not affect our health and will instead increase our well-being.

The tap water in Malaysia is derived from upstream dams rather than the water table, which absorbs contaminants from the soil. The primary dams providing water to Greater Kuala Lumpur (Klang Valley) are the Klang Gates Dam and Batu Dam.

To enhance chlorine’s disinfection effectiveness, the pH should be below 7. The National Drinking Water Quality Surveillance Programme (NDWQSP) survey found that the pH levels of tap water in 20 chosen regions ranged from 6.70 to 7.99, averaging 7.72. In Malaysia, chlorine is employed in the disinfection process for public water supply.

Based on the official guidelines, tap water in Malaysia is generally deemed safe for consumption as long as there is a sediment and chlorine filter. Nonetheless, a considerable number of Malaysians choose to either filter or boil the water before using it for drinking purposes. The convenient alternative is to use a water purifier at home or office.

Boiling the water ensures its safety for consumption in case of biological contamination. The bacteria and other organisms can be effectively eliminated by boiling water for a few minutes. Nevertheless, certain pollutants like lead are not as readily filtered out. Thus, it is recommended to filter tap water with water purifiers or water filters in Malaysia

As local authorities strive to ensure the safety of drinking water supplies, there remains a possibility of pollutants entering the water. Filters are an additional protective layer, eliminating even minimal traces of bacteria, heavy metals, and pesticides. This results in water that is not only more palatable but also healthier for consumption.
