Water statistics

Data extracted in August 2022

Planned article update: 30 June 2023


Among the EU countries, Croatia recorded the highest renewable freshwater resources (with a long-term average of 29 200 m³ per inhabitant) followed by Finland (19 900 m³) and Sweden (19 000 m³).

Total water fresh water use by the manufacturing industry in the EU varied from 186 m³ per inhabitant in the Netherlands (2019 data) to 4 m³ per inhabitant in Cyprus (2020 data).

The main sewage sludge treatment method varies within the EU: use as fertiliser for agriculture (Ireland, 89 % of total dry mass, 2020 data), composting (Hungary, 74 %, 2019 data), incineration (Netherlands, 96 %, 2020 data) or landfill (Malta, 100 %, 2020 data).

Share of external inflow from neighbouring territories in renewable freshwater resources - long-term average

Water is essential for life, it is an indispensable resource for the economy, and also plays a fundamental role in the climate regulation cycle. The management and protection of water resources, of fresh and salt water ecosystems, and of the water we drink and bathe in is therefore one of the cornerstones of environmental protection. This is why the EU’s water policy over the past 30 years is focused on the protection of water resources, ensuring that good quality water, in sufficient quantity, is available for all legitimate uses. The state of play is described by the fifth implementation report (2019) of the Water Framework Directive (2000), the central piece of environmental legislation concerning European waters. Recent insight about the quality of existing water related EU legislation and perspectives for its future development is offered by the Fitness check of the Water Framework Directive and related legislation (2019).

This article presents water statistics in the European Union (EU). It is based on data on freshwater resources, water abstraction, water use and wastewater treatment and disposal.

Water as a resource

Water resources refer to the freshwater available for use in a territory and include surface waters (lakes, rivers and streams) and groundwater. Renewable water resources are calculated as the sum of internal flow (which is precipitation minus actual evapotranspiration) and external inflow. Freshwater availability in a country is primarily determined by climate conditions and transboundary water flows (in other words, external inflows), while for total amounts, the size of the country matters. Freshwater resources per inhabitant are considered an important indicator for measuring the sustainability of water resources. When broken down by population, most countries' water resources range between 1  000 and 20  000 m³ per inhabitant, but in water-rich countries an inhabitant's share can be as high as around 29 200 m³ (Croatia) or 56 100 m³ (Norway). According to the World water development report of the United Nations, a country experiences ‘water stress’ when its annual water resources are below 1 700 m³ per inhabitant; among the EU Member States, this was the case in Poland, Czechia, Cyprus and Malta (where the lowest volume of water resources was recorded, at 164 m³ per inhabitant).

Table 1: Renewable freshwater resources - long-term annual average
(million m³)

A number of countries receive a significant proportion of their renewable freshwater resources as external inflow (see Figure 1). Among the EU Member States, Hungary and the Netherlands had the highest dependency on transboundary water resources, as the long-term average of external inflow accounted for 94.3 % and 88.8 % of their total renewable freshwater resources, respectively; the share in Serbia was also very high, reaching 92.3 %. In absolute terms (in other words, the volume of water received), the highest values are recorded for countries in the Danube basin: Croatia (93 783 million m³), Hungary (91 500 million m³), and Bulgaria (84 064 million m³) had the highest external inflows among the EU Member States (see Table 1), although Serbia recorded an even higher volume (158 135 million m³). At the other end of the scale, some countries have no or only negligible external inflow of water: the islands of Malta and Cyprus, as well as Spain and Denmark.

Water abstraction

There are considerable differences in the amounts of freshwater abstracted within each of the EU Member States, in part reflecting the size of each country and the resources available, but also abstraction practices, climate and the industrial and agricultural structure of each country. Between 2000 and 2020 — see Table 2 for the precise reference period covered for each EU Member State — the total volume of freshwater abstracted rose at its fastest pace in Denmark (+34.5 %), North Macedonia (+131.1 %), Turkey (+41.0 %) and Serbia (+40.4 %). The largest decreases were recorded in Lithuania (-82.6 %, due to a reduction in cooling water needs in electricity production), Slovakia (-50.9 %), Belgium (-44.6 %) and Estonia (-42.3 %). A remarkable development was observed in Greece: while the overall freshwater abstraction increased between 2000 and 2020 by 2.0 %, there is a strong divergence between abstraction of surface water that dropped by 40 %, and abstraction of groundwater that increased by 80 %.

Table 2: Total water abstraction, 2000 and 2020
(million m³)

Table 2 also shows the considerable differences between EU Member States as regards the ratio between abstractions from groundwater and surface water resources. Among the EU Member States, surface water abstraction accounted for around 8 times the volume of water abstracted from groundwater resources in Romania (2020 data) and Bulgaria (2019 data) and approximately 6 times in the Netherlands (2019 data). At the other end of the range, the volume of water abstracted from groundwater resources was around 13 times as high as the volume of surface water abstraction in Malta (2020 data, estimated) and 3.6 times in Denmark (2020 data, provisional).

Non-freshwater (in other words, sea water and transitional water, such as brackish swamps, lagoons and estuarine areas) is also abstracted in some of the EU Member States (see Table 2). Sweden (10 700 million m³; 2015 data), the Netherlands (6 249 million m³; 2019 data) and France (5 345 million m³; 2019 data) recorded the highest volumes of water abstracted from non-freshwater sources. In Malta, the volume of non-fresh water abstracted even dominates and reaches around 4.5 times the volume of fresh water abstracted (2020 data, estimated); it should be noted that much of this non-fresh water is used for the production of fresh water by desalination.

The long-term development of total freshwater abstraction per inhabitant is shown for selected EU Member States in Figure 2. A comparison of the earliest and latest available annual data between 1990 and 2020 shows that there was a marked decrease in abstraction in many of the Member States, especially those that joined the EU in 2004 or 2007. It is likely that the reduction in abstraction observed in many EU Member States is a result of various factors, including the reduction of water losses through improved maintenance of the networks, the introduction of water-saving household appliances and an increasing level of awareness concerning the cost or value of water and the environmental consequences of wasting it. In smaller countries, the removal of large abstractors, such as the closing-down of the Ignalina nuclear power plant in Lithuania at the end of 2009, can have a marked effect on the curve of total abstraction. The level of abstraction per inhabitant is primarily determined by the dominance of sectors requiring large amounts of water, such as irrigation in agriculture or cooling in electricity generation.

(m³ per year)

Water uses

The overall use of water resources can be considered sustainable in the long-term in most of Europe. However, specific regions may face problems associated with water scarcity; this is the case particularly in parts of southern Europe, where it is likely that efficiency gains in agricultural water use (as well as other uses) will need to be achieved in order to prevent seasonal water shortages. Regions associated with low rainfall, high population density, or intensive agricultural or industrial activity may also face sustainability issues in the coming years, which could be exacerbated by climate change impacts on water availability and water management practices.

Water is provided either by public water supply (public or private systems with public access) or is self-supplied (for example, private drills). While the share of the public water supply sector in total water abstraction depends on the economic structure of a given country and can be relatively small, it is nevertheless often the focus of public interest, as it comprises the water volumes that are directly used by the population.

At European level, households and the manufacturing industry (as defined by section C of the classification NACE Rev. 2) are both important users of water. However, their relative share varies greatly among European countries: while in the Netherlands and Belgium there is a clear (3-4 fold) dominance of water use by the manufacturing industry compared to the use by households (reflecting in part the relative importance of manufacturing industry in the economy of these countries), it is rather equal in Bulgaria and Turkey. In contrast, in countries with a dominance of the service sector and less industry, the water use by households can outweigh the use by manufacturing by far: Cyprus (23-fold use by households compared to NACE C), Latvia and Malta (both 8-fold) and Greece (6-fold) are prominent examples among the EU Member States.

Figure 3: Fresh water use by the manufacturing industry (NACE C) and households, from public water supply and self + other supply, 2020
(m³ per inhabitant)

Variation is likewise visible as regards the level of water use from public supply per inhabitant, where for households Greece and Cyprus lead the field among EU Member States with values around 100 m³ per year. On the other hand, countries like Lithuania and Romania manage to get along with just over a quarter of this top amount. The Netherlands and Belgium recorded the highest values for water use in manufacturing (186 and 102 m³, 2019 and 2018 data, respectively). Overall, the water use by households is much more uniform across Europe than the use by manufacturing, as basic water needs of the population are the same, while the industrial structure, and with that the water intensity of production, varies greatly.

Many EU Member States for which data are available (see Table 3) reported per inhabitant values for household water use from public water supply to be more or less stable over the last 3 decades (1990-2020). A marked increase could however be observed in Greece (+231 % from 2000 to 2020)), Lithuania (from 2005 to 2020) and Portugal (from 1989 to 2009). A larger group of countries reports a moderate to strong decrease (up to -40%), among them Belgium, Bulgaria, Czechia, Denmark, Germany, Italy, Poland and Romania, as well as Switzerland.

Table 3: Household water use from public water supply, 1990-2020
(m³ per inhabitant)

Self and other water supply is a major source of water for the manufacturing sector in several EU Member States as highlighted in Table 4. In the Netherlands, for example, self and other water supply accounted for 3 102 million m³ of water use in 2019, while public supply only accounted for 145 million m³. Similarly in Poland, where the figures were 622 million m³ and 21.2 million m³, respectively (2020 data). Likewise, the volume of water use from self and other water supplies was 35 times as high as that from public supply in in Latvia (2020), and 58 times in Turkey (2020).

Wastewater treatment and disposal

Overall, there is a development towards a higher proportion of the population being connected to wastewater treatment. Table 5 presents information on the proportion of the population connected to at least secondary wastewater treatment plants, which typically is an acceptable level on environmental protection unless the receiving waters are in a sensititve area. This share has been generally increasing over the past decades and was above 80 % in 16 of the EU Member States for which recent data are available (mixed reference years). The share of the population connected to at least secondary wastewater treatment plant even rose to 95 % and above in 6 Member States (Denmark, Germany, Luxembourg, the Netherlands, Austria and Sweden (mixed reference years)), as well as Switzerland and the United Kingdom. At the other end of the range, less than one in two households were connected to at least secondary urban wastewater treatment plants only in Malta and Croatia (2020 data), while the same was also true in Iceland (2010 data), Albania, Serbia (both 2020 data), and Bosnia and Herzegovina (2019 data). Over the time span shown (2002 - 2020), several countries managed to achieve a drastic increase in the coverage of their wastewater treatment, e.g. Cyprus (from 18.3 % to 82.7 %) and Portugal (from 27.0 % to 84.6 %).

Table 5: Share of the population connected to at least secondary urban wastewater treatment, 2002–2020

The residual of wastewater treatment is sewage sludge. While the amount of sludge generated per inhabitant depends on many factors and hence is quite variable, the nature of this sludge – rich in nutrients, but also often loaded with high concentrations of pollutants such as heavy metals – has led countries to seek different pathways for its disposal, as illustrated in Figure 4.

Figure 4: Disposal of sewage sludge from urban wastewater treatment by method of disposal, 2020
(% of total)
Typically, four different types of disposal make up a considerable share of the total volume of sewage sludge treated (2020 data unless otherwise stated): more than 80 % of the total was used as fertiliser for agricultural use in two EU Member States — Spain (87 %, 2018 data) and Ireland (89 %). A different way of making use of the nutrients in the sludge is composting; this was prevalent with more than 50 % in Finland (2019), Hungary (2019) and Cyprus (2018). Alternative forms of sewage disposal may be used to reduce or eliminate the spread of pollutants on agricultural or gardening land; these include incineration and landfill. As there are more and more environmental concerns about the latter, incineration is increasingly the method of choice: while the Netherlands (96 %), Belgium (75 %, provisional data), Germany (74 %, 2019 data), Austria (52 %), Greece (37 %, 2019) and Luxembourg (34%, estimated) reported incineration as their principal form of treatment for disposal, discharge into controlled landfills was practiced as the principal type of treatment only in Malta, Serbia, Bosnia and Herzegovina (in these countries it is the sole form of treatment), Romania (55 %) and Turkey (45%).

Data sources

Many of the water statistics produced by Eurostat have been used in the context of the development of EU legislation relating to water, as well as for environmental assessments, which in turn can give rise to new data needs.

Water statistics are collected through the inland waters section of the joint OECD/Eurostat questionnaire which is an established data collection yielding long time series, but which can also be adapted to meet the demands of relevant policy frameworks. It currently reports on the following:

  • freshwater resources in groundwater and surface water — these can be replenished by precipitation and external inflow (water flowing into a country from other territories);
  • water abstraction — a major pressure on resources, although a large part of the water abstracted for domestic, industrial (including energy production) or agricultural use may be returned to the environment and its water bodies (although often as wastewater with impaired quality);
  • water use — analysed by supply category and by industrial activities;
  • the share of the population connected to wastewater treatment plants — which gives an overview of the development status of the infrastructure, in terms of quantity and quality, that is available for the protection of the environment from pollution by wastewater;
  • sewage sludge production and disposal — an inevitable product of wastewater treatment processes, its impact on the environment depends on the methods chosen for its processing and disposal;
  • generation and discharge of wastewater — pollutants present in wastewater have different source profiles and, similarly, the efficiency of treatment of any pollutant varies according to the method applied [1].

In general, Eurostat collects national data. However some variables are also requested for river basin districts (according to the EU Water Framework Directive, see 'Context' below) by means of a regional questionnaire for some of the categories above.

A large amount of data and other information on water is accessible via WISE, the water information system for Europe, which is hosted by the European Environment Agency (EEA) in Copenhagen.


Water policies: floods, droughts and other challenges

The central element of European water policy is a Directive for ‘Community action in the field of water policy’ (2000/60/EC) — often referred to as the Water Framework Directive (WFD) — which aims to achieve a good ecological and chemical status of European waters. Together with its daughter legislation (Directive 0118/2006 and Directive 0060/2007), the WFD focused on water management at the level of (in most cases transboundary) hydrological catchments (river basins). An important step in the course of its implementation involved establishing river basin management plans. The latest state of play is summarised in the Commission's implementation report of February 2019 (COM(2019) 95 final).

In a Communication ‘Addressing the challenge of water scarcity and droughts’ (COM(2007) 414 final), the European Commission identified an initial set of policy options to be taken regionally, nationally and across the EU to address water scarcity within the EU. This set of proposed policies, which was reviewed and further developed by 2012, aimed to move the EU towards a water-efficient and water-saving economy, as both the quality and availability of water are considered as major concern in many regions.

In a Fitness check of the EU Water Framework Directive and related legislation (2019), the Commission identified strengths and weaknesses of the existing legislation and explored the need for possible amendments.


In an effort to reduce pollutants discharged into the environment with wastewater, the EU has implemented legislation on urban wastewater treatment (Directive 1991/271/EC). The pollution of rivers, lakes and groundwater and water quality is affected by human activities such as industrial production, household discharges, or arable farming; a report on the protection of waters against pollution by nitrates from agricultural sources (COM(2007) 120 final) was released in March 2007.

Another aspect of water quality relates to coastal bathing waters. The European Commission and the EEA present an annual bathing water report. The latest of these always covers information of the preceding year and shows that more than 95 % of the EU’s bathing waters met the minimum water quality standards.

Blueprint to safeguard Europe's water resources

These policy perspectives up to 2050 were developed in the ‘Blueprint to safeguard Europe's water resources’ (COM/2012/0673) which integrates the results of a policy review concerning: water scarcity and droughts; an analysis of the implementation of river basin management under the WFD; a review of the vulnerability of environmental resources (such as water, biodiversity and soil) to climate change impacts and man-made pressures; and a review of the whole of the EU’s water policy framework in the light of the European Commission’s ‘better regulation’ approach. The blueprint is closely related to the Europe 2020 strategy and, in particular, to the resource efficiency roadmap (COM(2011) 571). However, the blueprint covers a longer time span, through to 2050, and is expected to drive EU water policy over the long term. As part of the blueprint there are a number of policy reviews assessing implementation.
