Overview
Kurtna Pohi is a secondary treatment plant serving 138 people in Kiisa, Estonia. It discharges 31.80 m³/day of treated wastewater, operating under EU Urban Waste Water Treatment Directive standards.
Kurtna Pohi is a municipal wastewater treatment plant located in the village of Kurtna, near Kiisa in Harju County, Estonia. The plant serves a small population of 138 residents, reflecting the rural character of the area. Its location in the northern part of Estonia places it within the broader Baltic Sea catchment. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 315 m³/day and a current discharge volume of 31.80 m³/day, the plant operates well below its capacity, indicating room for future growth. The facility is part of Estonia's national wastewater infrastructure, which is regulated under the country's implementation of EU directives. The treated effluent from Kurtna Pohi eventually drains into the Baltic Sea via local streams and rivers. The Baltic Sea is a sensitive brackish water body with limited water exchange, making nutrient removal important for preventing eutrophication. The plant's secondary treatment helps reduce organic load and protect downstream aquatic ecosystems.
Environmental context
The plant discharges into local watercourses that flow into the Baltic Sea, a semi-enclosed sea with high ecological sensitivity. The Baltic Sea suffers from eutrophication due to nutrient inputs from agriculture and wastewater. Secondary treatment at Kurtna Pohi removes a significant portion of organic matter and nutrients, helping to mitigate this issue. The surrounding region includes forests and agricultural land, which influence runoff patterns.
