Overview
SIA Jurmalas udens Mezmalas 41 Jurmala is a wastewater treatment plant serving approximately 28,668 people in Jūrmala, Latvia. Located near the Baltic Sea coast, it plays a key role in protecting the region's coastal waters.
SIA Jurmalas udens Mezmalas 41 Jurmala is a municipal wastewater treatment plant located in the coastal city of Jūrmala, Latvia. The plant serves an estimated population of 28,668, placing it in the medium agglomeration category under EU regulations. Its location near the Baltic Sea underscores the importance of effective wastewater management to safeguard marine environments. As a facility in Latvia, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a scale appropriate for its service population. The plant's treated effluent ultimately reaches the Baltic Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Proper treatment helps prevent eutrophication and protects marine biodiversity. The plant contributes to the health of the Gulf of Riga and the broader Baltic ecosystem, supporting tourism and local fisheries.
Environmental context
The plant discharges into the Baltic Sea via the Gulf of Riga, a brackish water body that is ecologically sensitive due to its limited water exchange and susceptibility to eutrophication. The surrounding watershed includes coastal forests and wetlands that provide habitat for migratory birds and aquatic species. Effective nutrient removal at the plant is critical to reducing algal blooms and maintaining water quality in this important marine environment.
