Overview
BAI Daugavgriva is a large wastewater treatment plant serving approximately 606,000 people in Latvia. It is located near the coast and plays a key role in the country's wastewater management infrastructure.
BAI Daugavgriva is a major wastewater treatment plant in Latvia, serving an estimated population of 606,020. The plant is situated near the Baltic Sea coast, reflecting its strategic importance for managing urban wastewater from the surrounding region. As a large-scale facility, it is subject to stringent national and European Union regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent exceeding 150,000 are classified as 'large agglomerations' and must implement tertiary treatment when discharging into sensitive areas. Given its coastal location, BAI Daugavgriva likely operates under such requirements to protect the marine environment. The plant's designed capacity is 1.00 (units unspecified), indicating its substantial scale. The treated effluent from BAI Daugavgriva ultimately discharges into the Baltic Sea, a semi-enclosed sea with limited water exchange and high ecological sensitivity. The plant's operations are critical for preventing nutrient pollution and safeguarding the coastal ecosystem, which supports diverse marine life and is an important area for fisheries and tourism.
Environmental context
The plant discharges into the Baltic Sea, a brackish water body with unique ecological characteristics and high vulnerability to eutrophication. The surrounding watershed includes coastal wetlands and estuaries that serve as critical habitats for migratory birds and fish species. Effective wastewater treatment is essential to minimize nutrient inputs and protect the sea's biodiversity.
Frequently asked questions
BAI Daugavgriva is located in Latvia, near the Baltic Sea coast at coordinates 57.044°N, 23.955°E.
The plant serves approximately 606,020 people, making it a large agglomeration under EU classification.
The treated effluent is discharged into the Baltic Sea, a sensitive marine environment requiring advanced treatment to prevent eutrophication.
As a large coastal plant in the EU, it operates under the Urban Waste Water Treatment Directive (91/271/EEC), which mandates tertiary treatment for sensitive areas.
For large agglomerations in Latvia, EU directives require at least secondary treatment, with tertiary treatment for discharges into sensitive coastal waters like the Baltic Sea.
