UWWTP_BOROVNICA Wastewater Treatment Plant, Laze pri Borovnici, Slovenia

UWWTP_BOROVNICA is a municipal wastewater treatment plant located in Laze pri Borovnici, a settlement in the Municipality of Borovnica, Slovenia. The plant serves a small population of 595 people, reflecting its role in managing domestic wastewater for this rural community. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. The designed capacity of 1,000 m³/day indicates the plant's scale is appropriate for the served population. The treated effluent is discharged into the local water environment, likely contributing to the Ljubljanica River basin, which flows through the Ljubljana Marsh and eventually into the Sava River. The Sava River is a major tributary of the Danube, ultimately draining into the Black Sea. The plant helps protect the sensitive karst landscape and groundwater resources in the region.

The plant's discharge enters the local watershed, which is part of the Ljubljanica River basin. This river flows through the Ljubljana Marsh, an ecologically important wetland area that supports diverse aquatic life and acts as a natural water filter. The water eventually reaches the Sava River, a major Danube tributary, and then the Black Sea. The region's karst geology makes groundwater particularly vulnerable to contamination, so effective wastewater treatment is crucial for protecting both surface and groundwater quality.
