By continue reading you will find more details about tap water in Slovakia like the general rules for drinking water in different common places and above all, I’ll show you what the signs for potable and non-potable tap water look like. Enjoy the article!

Overall Quality of Slovak Tap Water

The quality of Slovak tap water is extremely high. Why? First of all, most of it comes from the mountains and the natural sources are well-preserved and clean. Other than that:

  • a relatively huge amount of sources only need disinfection to make their water potable
  • the only possible damage to its quality can be caused by old pipes – and even that at the end of the pipe, in the consumer´s household
  • the pipe system is taken care of and only particular places (old edifications with an extremely circulation of people daily like student residences) might content limescale
  • a stabilized water (has the right calcium-carbon balance) creates an incrustation on the pipe´s surface so the water and the pipe don´t represent any serious threat to each other
  • due to contemporary technologies, the levels of chlorine are low and it wears out quickly on the air

When talking about possible interventions and modifications, it is worth mentioning that Slovakia has many springs, especially in the mountains, that serves well the purpose of providing potable water for the inhabitants. That means the water from these springs only needs to be disinfected and that is all. Others undergo only minor processes of filtration and purification.

Interesting fact: The average consumption of tap water per capita is between 100-150 liters per person daily, which puts Slovakia only in the middle of the list when it comes to European countries.

These two signs are crucial. Some signs may be a little different, but in principle they will all be similar to the signs you see above. And most importantly, the text will always be the same. Now take a look at the general rules for tap water in the most common Slovak places:

Place / LocationIs tap water safe?
HouseholdsMost of households have potable tap water. For sure, it is always better to ask the owner.
Room in HotelsWatch for the signs next to the sink or water tap in the bathroom. When there is no sign it means the water is potable. Almost all of the hotels should have potable water in the rooms or their bathrooms.
Room in HostelsSame rules as for hotels. What the signs first, when you do not see any signs – ask the owner or receptionist.
RestaurantsYou can always ask the waiter for the tap water and you should get it for free (or a very low price). Tap water on toilets in restaurants should be potable (always look for the sign).
Public toiletsIt is not recommended to drink tap water on public toilets. But it does not mean it can’t be potable water. You should find a sign of whether the water is potable or not on public toilets.
Toilets on Gas stationsThe same situation as for public toilets. It is not recommended to drink tap water on toilets on gas stations but this tap water can be potable.
Natural springsIf the spring is drinkable, you will often find cups or some modified surroundings of the spring. Water in a lot of the natural springs in the moutains is potable.
RiversThe water in the rivers is NOT potable and it is not alowed to drink water from any river in Slovakia.
LakesThe same situation as for rivers. The water in lakes is NOT potable and it is not allowed to drink water from any lake in Slovakia (not even in High Tatras)
Where is Safe to Drink Tap Water in Slovakia?

By reading this table you should be able to know where drinking tap water is safe and where it is not safe. So I hope it helps you during your visit in Slovakia. Because if you want to enjoy your stay in Slovakia, the most important thing is to stay safe.

Even though Slovakia´s water is in excellent condition, today´s lifestyle and the fact surface water is easily polluted make it impossible to use Slovak rivers and lakes as an everyday source of drinking water.

What Makes Slovak Tap Water so High Quality?

Independently of whether the original water is only disinfected, filtrated, or undergoes technological interventions, a quality tap water:

  • comes from a good source
  • has low levels of Ferrum and Mangan
  • has low levels of nitrates
  • has only a moderate amount of chlorine
  • is brought to households through good quality pipes, cleaned and not too old
  • it has undergone disinfection – that´s the minimal requirement

Slovak tap water has all these symptoms controlled and often even comes from such pure sources that it only needs to be disinfected. Nevertheless, it needs to be mentioned that tap water, even though having been boiled, is not suitable for babies – and that goes for all around the world (it is suitable only after boiling). There are only few areas in which tap water can be used for nursed babies, even in Slovakia.

That brings us to eighty-six percent of Slovak households having access to clean tap water. Most Slovak consider it automatic to simply turn on the tap and treat themselves with water whose quality they can rely on. Tap water in Slovakia maintains a very high level of quality, actually one of the best around the world. What does it come from? Mountains are home to many water sources and Slovakia proud itself of its mountainous character. Here are some useful facts:

  • when saying “mountain water”, we need to keep in mind that “groundwater” is what we are talking about, since it provides 80 percent of Slovakia´s water reserves
  • while in most countries, the term “groundwater” refers only to sources that can create a coherent water surface, in Slovakia, “groundwater” refers to any water found other than on the surface in the country´s ground areas, it means terrain or geest, too
  • the 20 percent of the water that comes from the surface, is concentrated in dams or are subducted straight from the rivers.

TIP: A large part of the underground water supply in Slovakia is formed by thermal or healing springs. A large number of spas and water parks have sprung up in the vicinity of the thermal springs. Read about the best of them in the article below:

The Sources of Tap Water in Slovakia

The biggest groundwater reservoir of potable water in Slovakia is Žitný ostrov, in the south of the country. It is the largest river island in Europe and it is a reliable source of water of excellent quality, actually the biggest one in Central Europe.

  • it contains 10 billions cubic meters of water
  • southern Slovakia is mostly agricultural, hence the almost non-existing industrial pollution
  • fertilizers do affect the water, but not in a significant way
  • most rivers in the country flow toward the south and contribute to the reservoir with their water
  • the same fact, however, means a higher concentration of nitrates

The Most Important Reservoirs Dams in Slovakia

Most surface water in the country comes from reservoirs filled with mountain water. Most of these reservoirs were built during the 1960s as part of the industrialization of the country. People were moving to towns where freshwater was impossible to find and the growing industry required freshwater sources to be led to dams at the population´s disposal.

Starina reservoir

The biggest reservoir is Starina, located on the Cirocha river. It lies in the biospheric natural reserve Bukovské vrchy, protected by UNESCO and situated in Východné Karpaty.

  • It was built in 1983-1988 and serves for providing the eastern regions of the country with potable water. 
  • It spreads onto 320 ha (approx. 790 acres)
  • The dam´s barrier is 50metrs high
  • The volume of water comes to 60 million cubic meters
  • The volume of the outflow is 1,300l of water per a second
  • For its construction, the inhabitants of seven villages had to leave their homesň

Bukovec reservoirs

The Ida river is home to not one, but two reservoir dams. They serve mostly for Košice inhabitants and were built for a particular purpose: Košice´s metalworks brought in many new people and easily accessible potable water was the main condition as much of securing the living standard of the thousand of its workers, but of the construction itself.

  • Bukovec´s volume is 1,7 million cubic meters of water and was built in 1964-1966.
  • Bukovec II contains 21, 4 million cubic meters of water, and its construction dates back to 1968-1976. 
  • They are both located near the Bukovec village near Košice.

Turček reservoir

One of the youngest dams is the Turček reservoir in Štiavnicke vrchy in Central Slovakia. The region is famous for its mining, and a water pipe was built here already in the 15th century to provide water for the mining processes and smelteries. Local industry has been using its water ever since and in 1992, a reservoir was built here to provide more potable water for the region.

Other notable reservoirs that provide potable water

  • Hriňová dam on the Slatina river provides potable water for Central Slovakia. It was built in 1960-1965 and contains 7,5 million cubic meters of water.
  • Klenovec on the Rimava river dates back to 1968-1974 and contains 6,9 cubic meters of water.

Interesting fact: Despite the extraordinary amounts of clean water, to protect it, Slovakia doesn´t export it. Theoretically, the water from Slovakia could serve to tap a whole other country, if not several, but climate change is endangering also Slovak sources, and dry summers are no exception here, either.

Bottled water often comes from the tap as well, so when choosing between pouring yourself a glass of water straight from the tap and opening a new plastic bottle, the choice is clear. The first one is way more natural.
