UWWTP_SENTILJ JUG - Secondary Wastewater Treatment Plant in Šentilj, Slovenia

UWWTP_SENTILJ JUG is a municipal 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 123 residents, reflecting its role in a rural community. It is situated along Mariborska cesta, a local road connecting to the regional center of Maribor. The plant 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 2,000. With a designed capacity of 1,000 m³/day and an actual discharge volume of 161.23 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local watercourse, which ultimately drains into the Mura River, a tributary of the Drava River, and then into the Danube River basin. This waterway supports diverse aquatic life and is part of the larger Danube catchment, which flows into the Black Sea. The plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids.

The plant discharges into a local stream that flows into the Mura River, a major tributary of the Drava River. The Drava joins the Danube, which empties into the Black Sea. This watershed supports diverse aquatic ecosystems, including fish species such as the Danube salmon and various migratory birds. The secondary treatment level reduces organic load and suspended solids, helping to maintain water quality in the downstream river network.
