Overview
UWWTP_VIPAP serves Krško, Slovenia, treating wastewater for approximately 175,000 people. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP_VIPAP is a municipal wastewater treatment plant located in Krško, Slovenia, serving a population of around 175,000. As a large agglomeration under EU classification, the plant is subject to stringent treatment requirements to protect the local environment. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations larger than 150,000 population equivalent must provide secondary treatment, and tertiary treatment if discharging into sensitive areas. Slovenia, as an EU member state, enforces these standards through national legislation. The treated effluent from UWWTP_VIPAP is discharged into the Sava River, which flows through Slovenia and Croatia before joining the Danube and ultimately reaching the Black Sea. The Sava River supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
UWWTP_VIPAP discharges into the Sava River, a major tributary of the Danube River system. The Sava River basin is ecologically significant, supporting diverse fish species and providing habitat for migratory birds. The Danube eventually flows into the Black Sea, making the treatment plant's performance important for downstream water quality across multiple countries.
