UWWTP kkBorovetz Yaitzeto - Advanced Wastewater Treatment in Borovets, Samokov, Bulgaria

UWWTP kkBorovetz Yaitzeto is an advanced wastewater treatment plant located in the Borovets resort area, within the municipality of Samokov in Sofia Province, Bulgaria. The plant serves the tourism infrastructure of Borovets, one of Bulgaria's premier ski destinations, and is part of the country's efforts to manage wastewater in mountainous regions. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent discharge standards. Under Bulgarian and EU regulations, such facilities are required for sensitive areas to protect water quality. The plant's discharge volume is reported at 360.88 cubic meters per day, indicating a scale appropriate for a seasonal resort population. The treated effluent is discharged into the local watershed, which drains into the Iskar River, a major tributary of the Danube. The Iskar River flows northward through the Balkan Mountains and eventually reaches the Danube Delta and the Black Sea. The plant plays a key role in preserving the ecological integrity of the Rila Mountains, a region known for its biodiversity and as a source of drinking water.

The plant discharges into the Iskar River basin, which flows through the Rila Mountains and eventually joins the Danube River, ultimately reaching the Black Sea. The Rila Mountains are ecologically sensitive, supporting diverse aquatic life and serving as a critical water source for the region. The advanced treatment helps protect downstream ecosystems, including the Iskar Reservoir, which supplies drinking water to Sofia.
