UWWTP_SENTILJ MEJA Wastewater Treatment Plant, Šentilj v Slovenskih goricah

UWWTP_SENTILJ MEJA is a wastewater treatment plant located in Šentilj v Slovenskih goricah, a settlement in northeastern Slovenia near the Austrian border. The plant serves a small population of 516 residents, reflecting the rural character of the area. The facility provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 10,000. The plant has a designed capacity of 3000 m³/day and currently discharges 406.15 m³/day of treated effluent. The treated wastewater is discharged into local watercourses that eventually drain into the Mura River, a tributary of the Drava, which flows into the Danube and ultimately the Black Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from untreated sewage pollution.

The plant discharges into small streams in the Mura River basin, which flows into the Drava River and then the Danube, reaching the Black Sea. The area supports diverse aquatic life and is part of an important migratory corridor for fish species. The secondary treatment helps reduce organic load and nutrients, protecting downstream water quality in this ecologically sensitive region.
