Overview
Loksa reoveepuhasti is an advanced wastewater treatment plant serving 2,800 people in Loksa, Estonia. It discharges 645.12 m³/day of treated effluent and is located within 10 km of the Baltic Sea coast.
Loksa reoveepuhasti is the municipal wastewater treatment plant for the town of Loksa, located in Harju County, Estonia. The plant serves a population of approximately 2,800 residents and operates with a designed capacity of 4,500 m³/day, currently treating 645.12 m³/day of wastewater. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (2,800 PE), the directive mandates secondary treatment, but the plant's advanced level indicates additional nutrient removal or polishing, likely to protect the sensitive coastal environment. The treated effluent is discharged into the Baltic Sea, as the plant lies within 10 km of the coast. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The advanced treatment helps reduce the risk of eutrophication in this ecologically important marine environment.
Environmental context
Loksa reoveepuhasti discharges treated wastewater into the Baltic Sea, a brackish inland sea connected to the North Atlantic via the Danish straits. The Baltic Sea is highly sensitive to nutrient inputs, which can cause algal blooms and oxygen depletion. The plant's advanced treatment helps protect this fragile marine ecosystem by reducing nitrogen and phosphorus loads.
