Connecting the public to the public water supplies

Last update of indicator 16.12.2021

Indicator definition

This indicator expresses the percentage of inhabitants supplied with drinking water from  the public distribution water supply network.




Key messages

Development trend in public water supplies shows regional irregularity, with shortage of groundwater sources in passive areas being one of the critical factors. (e.g. south regions of central Slovakia and majority of eastern Slovakia)
Number of inhabitants supplied with drinking water from the public water supplies in 2020 reached the  89.81 %, which is an increase by 4.4 % compared to 2005. Despite the fact that the number of inhabitants connected to public water supplies has been growing, drinking water abstractions from water management facilities show reduction. This reduction can be seen also in specific water consumption in households that has been falling from year to year and its value recorded in 2020 (80.84 alarmingly approached the sanitary minimum.
Mainly groundwater has been used as the drinking water sources in Slovakia (more than 80 %), with less than 20 % of drinking water coming from surface water sources.

International comparison

The OECD Green Growth database contains selected indicators for monitoring progress towards green growth to support policy making and inform the public at large. The database provides a synthesis of data and indicators available across a wide range of domains. The sources of the underlying data used to populate the Green Growth Indicators, as presented here, include a range of OECD databases and, in some cases, external data sources. The database covers OECD member countries, accession countries and selected non-OECD countries (including the BRIICS economies - Brazil, Russian Federation, India, Indonesia, China and South Africa).

OECD Green Growth Indicators Database


Ing. Ľubica Koreňová, SAŽP,


Selection and methodology of indicator’s assessment is based on the set of indicators proposed by the OECD and addressed by the report: "Green Growth: Monitoring progress towards green growth“. Data relating to the national situation are usually presented in the period between 2000 and 2012. Basic time sequence is changed in those cases when the data are not accessible or when their comparison is not possible due to differing approaches in their collection, assessment, changes in methodology, classification, etc.  Summary assessment of indicator’s trend from the green growth perspective is based on a subjective evaluation of the responsible assessor due to the fact that the strategy is not officially implemented in the Slovak Republic and therefore specific objectives have not been defined.  Naturally, this assessment builds on the analysis of the past trends, as well as their anticipated direction in view of the measures adopted as to date.
Selected indicators characterize Slovakia's initial position as seen from the perspective of the green growth and were to be used as a measuring tool before further steps are taken in the process of implementation of this strategy and for a complex assessment of the future trend of the Slovak economy.  Present set of green growth indicators comprises 32 individual indicators that are relevant in Slovakia's conditions. Four of them are national indicators that describe voluntary instruments of the environmental strategy.

Data sources:

Data used in this document come from the official national or international sources and databases.  Assessed trend was reviewed and discussed with the state administration specialists (individual departments of the ministries of Environment, Economy, Labour and Social Affairs and Family, Finance, Agriculture and Rural Development) and their professional organisations (Slovak Hydrometeorological Institute, State Geological Institute of Dionýz Štúr, Slovak Environmnet Agency, State Nature Consservancy, Institute for Financial Policy) and also the Statistical Office of the Slovak Republic whose databases furnish most of the information.
