PU Livanu dzivoklu komunalas saimniecibas parvalde - Advanced Wastewater Treatment in Turku pagasts, Latvia

PU Livanu dzivoklu komunalas saimniecibas parvalde is an advanced wastewater treatment plant located in Turku pagasts, Līvānu novads, Latvia. The facility serves a population of approximately 4,559 people, classifying it as a small to medium agglomeration under EU standards. Its designed capacity is 10,000 m³/day, with a current discharge volume of 966.93 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a Latvian facility, it operates under national regulations that transpose EU directives, ensuring compliance with discharge standards. The treated effluent is discharged into local water bodies within the Daugava River basin, which ultimately flows into the Baltic Sea. The plant plays a key role in protecting downstream ecosystems, including the Gulf of Riga, by reducing nutrient loads that could cause eutrophication. Its advanced treatment helps maintain water quality in a region where agricultural and urban runoff are significant concerns.

The plant discharges into the Daugava River basin, which drains into the Gulf of Riga and the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea highly sensitive to nutrient pollution, making advanced treatment crucial for controlling eutrophication. The local watershed supports diverse aquatic life and is an important migratory corridor for fish species. The plant's advanced treatment helps reduce nitrogen and phosphorus loads, mitigating algal blooms and preserving ecological balance in downstream waters.
