Environmental context

The plant discharges into the Daugava River basin, which flows into the Gulf of Riga and the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Secondary treatment at this plant helps reduce organic load and nutrients, supporting the ecological health of the downstream river and coastal waters, which are important for fisheries and biodiversity.
