UWWTP_IVANCNA GORICA Wastewater Treatment Plant, Muljava, Slovenia

UWWTP_IVANCNA GORICA is a wastewater treatment plant located in Muljava, a settlement in the Ivančna Gorica municipality of central Slovenia. The plant serves a population of approximately 16,022, classifying it as a medium agglomeration under EU regulations. Its location in the Dinaric Alps region influences local hydrology and treatment requirements. As a Slovenian facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalents. For sensitive areas, more stringent tertiary treatment may be mandated. The plant's treatment processes align with these regulatory standards to protect downstream water quality. The treated effluent is discharged into the local watershed, which drains into the Krka River, a tributary of the Sava River, and ultimately flows into the Danube River basin and the Black Sea. This connection to a major European river system underscores the plant's role in regional water quality management and the protection of aquatic ecosystems downstream.

The plant discharges into the local watershed that feeds the Krka River, a karst river in southeastern Slovenia. The Krka flows into the Sava River, a major Danube tributary, which carries water to the Black Sea. The region's karst geology makes groundwater particularly vulnerable to contamination, so effective wastewater treatment is critical for protecting both surface and groundwater resources. The downstream environment supports diverse aquatic life, including fish species such as the Danube salmon, and provides important ecosystem services.
