[ZD05] Access to safe drinking water
Responses

Key message
Neutral

In 2019, 93% of the Slovenian population used drinking water from the drinking water supply systems. This includes 858 supply zones with regular monitoring of drinking water quality at the user tap. In 2019, regular monitoring of the drinking water did not include 7% of the Slovenian population. This is because regular monitoring is not obliged for the supply systems with less than 50 people (own drinking water supply, self-sufficiency). Generally, all residents of Slovenia living in cities used regulary monitored drinking water. Access to drinking water slightly improved in the period 2004–2019.
