Environmental context
Ikskiles NAI discharges into the Daugava River basin, which flows into the Gulf of Riga, part of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea sensitive to eutrophication from nutrient inputs. The plant's secondary treatment helps reduce organic matter and nutrients, mitigating algal blooms and oxygen depletion in downstream waters. The Daugava River supports diverse fish species and is an important migratory corridor for salmonids.
