[ZD05] Access to safe drinking water
Key message
In Slovenia in 2017, 94% of the population was supplied with drinking water from water supply systems that had undergone water quality monitoring in situ, at users’ taps. Drinking water monitoring excluded 6% of the Slovenian population. Generally, all residents of Slovenian cities are supplied with drinking water subjected to regular monitoring. Accessibility of drinking water did not improve significantly in the period 2004–2017.

Goals
- To provide access to safe drinking water in sufficient quantities to all inhabitants of Slovenia;
- to connect inhabitants, particularly those supplied by small and poorly managed systems, to large, professionally managed and controlled water supply systems or to improve the management and technical compliance of small systems according to equal principles to ensure safe drinking water for everyone;
- to carry out monitoring of all systems within the parameters of regular and periodical testing of samples;
- to inform inhabitants connected to small systems supplying fewer than 50 people that the Rules on drinking water are not implemented in these systems (there is no monitoring and control), inform them of possible measures to protect health from harmful factors and to forward them recommendations for acting in the event of reasonable suspicion that drinking water represents a potential hazard to human health.
