Slightly more water abstracted 

183 million cubic metres of water were abstracted in Slovenia in 2023, which is 2.0% more than in the previous year. 179 million cubic metres of water (or 2.2% more) were abstracted from groundwater – of which 64.3 million from springs, while 4.1 million cubic metres of water (or as much as a year earlier) were abstracted from surface water.

The amount of water abstracted from the Danube river basin went down by 0.4% and from the Adriatic Sea river basin up by 15.3%.

Households consumed less, businesses consumed more 

Households consumed 82 million cubic metres of water from the public water supply or 4.2% less than in the previous year, while business entities consumed 42.8 million cubic metres of water or 13.0% more.

4.6 million cubic metres of water were supplied but uncharged (water from hydrants, water for firefighting, water for cleaning roads, etc.), which is 4.7% more than a year before, and 53.7 million cubic metres of water were lost as a result of poorly maintained networks, which is 4.3% more.

Slightly more connections to the water supply network

The entire water supply network in 2023 was 44,779 kilometres long, while, compared to the end of the previous year, the number of connections to the water supply network increased by 7.2% to 573,695.
