Overview
Merikula wastewater treatment plant in Harju maakond, Estonia, serves 1,300 people with advanced treatment. It discharges 299.52 m³/day and has a designed capacity of 1,650 m³/day.
Merikula wastewater treatment plant is located in Meriküla, Harku vald, Harju maakond, Estonia, near the Baltic Sea coast. The plant serves a population of approximately 1,300 people, classifying it as a small agglomeration under Estonian and EU regulations. The plant provides advanced treatment, which goes beyond the EU Urban Waste Water Treatment Directive's minimum requirement of secondary treatment for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 1,650 m³/day and currently discharges 299.52 m³/day of treated wastewater. The treated effluent is discharged into the local environment, likely into the Baltic Sea via coastal waters. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication in the coastal zone.
Environmental context
The plant discharges into the Baltic Sea, a brackish water body with limited circulation, making it highly sensitive to nutrient inputs. The coastal waters near Harju maakond support diverse marine life and are important for local fisheries and recreation. Advanced treatment helps mitigate eutrophication risks in this ecologically sensitive area.
