More water abstracted from surface waters

In total, 957 million m3 of water was abstracted in Slovenia, which is 1% more than in the previous year. Four fifths (80%) of water was abstracted from surface waters, which is 770 million m3. Business entities registered in industrial activities (sections B, C, D and E by NACE Rev. 2) abstracted a large majority of it: 770 million m3. 3.2 million m3 of water was abstracted from surface waters for the public water supply system and 3 million m3 for irrigation.

Most water abstracted from groundwater sources for public water supply
 
19.5% of abstracted water (187 million m3) was taken from groundwater sources. Most of it (166 million m3) was abstracted for the public water supply system, while 20 million m3 of groundwater was abstracted by industrial enterprises and just over half a million m3 was intended for irrigation.

More wastewater discharged into the environment

1,013 million m3 of wastewater was discharged into the environment, which is 0.7% more than a year earlier. Of this, 761 million m3 of wastewater was only heat-polluted, 194 million m3 was treated before discharge and 58 million m3 was untreated.

The majority of wastewater (76.0%) was discharged into surface waters, 23.7% into the public sewage system, and the remaining 0.3% into soil.

Wastewater includes not only the amount of water that was discharged after use back into the environment, but also runoff rainwater, which flows back to the environment through the sewage system or is captured and discharged directly into rivers, streams or soil.
