Can You Drink Tap Water in Johor Bahru?

Yes, tap water is drinkable.

Tap Safe includes data from many publicly available sources, including the WHO (World Health Organization), CDC (Center for Disease Control), and user submitted databases, but unfortunately there's not enough data about Johor Bahru.

Johor Bahru Tap Water

The Johor Bahru tap water is considered by many to be a very safe and pure water source. It has the Health Ministry’s approval in Malaysia and even carries the seal of the Malaysia Development Institute (MDA). The problem with this is that there have been reports showing the tap water at the neighboring communities of Limah, and Jalan Raya Ubud has also had the same certification. This is not saying that all the tap water coming from the different reservoirs in the cities of Johor and Bekal is unsafe. Some scientists are urging people to take precautionary measures when using it for drinking or for cooking purposes.

While it is true that the tap water at the neighboring areas has MDA certification, it does not necessarily mean that every drop of water has been certified safe for human consumption. This is because, while the MDA says that specific standards have been followed, they also state that these standards are not always enough to ensure your safety. For one thing, they only look at the methods used to purify the water and do not check on the contaminants present in the liquid itself. The standards only cover the water’s external appearance but fail to address the source of contamination inside the body. This means that you may be consuming toxins that are harmful to your health.

There are many ways to determine if the water from the tap in your community is indeed safe for consumption. One of the best ways is by getting hold of a couple of water testing kits that are readily available in the market. Once you have them, you can quickly test your water for contaminants and determine whether it has any harmful toxins that you need to get rid of immediately. If you do not have these kits, you can also try asking your community members where they get their water from. They may give you the information that you need.

Johor Bahru Drinking Water

Johor Bahru drinking water is considered to be safe according to the water purifier industry. Private companies often provide the drinking water in Johor as part of a marketing campaign, but it still has to meet specific standards. These companies sometimes install their filtration system instead of using a third-party company. The government does not advise against using bottled water and encourages the use of water purifiers. However, the use of bottled water is regulated by the Malaysia Water Development Board, which does not allow companies to give their customers’ tap-water treatment facilities’ certificates.

If you’re worried about the safety of your drinking water, you can have peace of mind knowing that the water in your home is treated at a state-of-the-art plant. When a bottled water company puts a label on their product that it is filtered and purified at a facility owned by the company, people automatically assume that it must be clean and safe. Still, there are some things to watch out for. The bottled water company may only be licensed to process glass products, so they can’t do anything for the chemicals and metals found in water. It’s recommended that the company you buy from uses a glass vessel that’s been run through a multi-stage selective filtration device.

A multi-stage selective filtration system is considered one of the best methods available for removing all contaminants. Still, it cannot remove every chemical and mineral in your tap water. Even if a business uses glass bottles, they still have to go through a purification process before selling them to the public. That’s why it’s essential to choose carefully when shopping for a drinking water purifier. You want to get one that works best for you.

Johor Bahru Treatment Plant

Johor Bahru is the capital city of Malaysia and has a pretty good water supply. However, its proximity to the sea and its sandy soil attract many people to have their drinking water tested here at the Water Treatment Plant (WTP). The main aim of this WTP is to provide a quality public water supply by purifying raw seawater and then treating it using disinfectants before supplying it to the public. The Water Treatment Plant, also known as the WTP, is managed by the Johor Bahru City Government (BJPG) and was established in 1965. The Water Treatment Plant has been receiving excellent service from all the major public utilities around the world. However, there are still some criticisms against the system of the WTP.

The most significant complaint that I hear from the Water Treatment Plant customers is that its sanitation measures are not sufficient. For example, I know of a family in JKL that gets their water supply from the Johor state municipality, but they have to go to the Water Treatment Plant to get clean water. This has often lead to problems between the family members, as some residents complain that they are not being treated well while others say they are. For this reason, it is recommended that you do a regular checkup of the sanitation system of your water supply. The Water Treatment Plant does an excellent job of maintaining the cleanliness of the water supply. If you know the nearest WTP, you can drop by and have a look.

Apart from the WTP, the Johor water supply project also involves the construction of the National Waterfront. The project involves several different projects, including the extension of the existing JKL International Airport, development of the Waterfront, and a new airport, namely the East Coast Express (ECE). The entire project is being managed by the Sabah state government, which is doing its best to encourage private investment. At present, the Waterfront Development Company is undergoing a 20-year botanical management engagement with the Malaysia Green Development Institute (MNGI). The botanical management engagement is aimed at managing the waterfront property to enhance the overall environment.

Johor Bahru Water Quality

The Johor Bahru water quality test site is located in the Central Malaysia region. It is also known as the Blue Water River. This particular area is located along the east coast of the Peninsula of Macau. If you are one of those interested in knowing what the quality of the water we drink is in our area, then this is the place for you. Many reports and laboratory tests have been carried out here and have revealed excellent water quality levels.

The water here is clean and pure and does not contain any bacteria or harmful chemicals. There are different water bodies here, which are connected by rivers, creeks, and sea. One of these is the East Coast Drainage Area, and the other is the West Coast Drainage Area. Each of these regions has its water resource, and water flows into it. You need to be aware that several pollution problems occur in the East Coast Drainage area because of the number of ferries and cruise liners that go to this area.

Meanwhile, the West Coast Drainage Area is filled with dirt, trash, rubbish, and factories that have been built in an attempt to divert the water. The water that flows into this area is dirty and contains a lot of garbage. Another major problem here is that there is no sewage treatment plant in this area. People that live here have to use boreholes to access clean water.


Tap water should be boiled before drinking. As a rule of thumb, the general hawker food scene in Johor Bahru is hygienic though certain areas are less so. So keep an eye out for those dirty hawkers who pay very little attention to hygiene.
