Overview
Priekules NAI is a secondary treatment plant serving 492 people in Priekule, Latvia. It discharges 158.68 m³/day and has a designed capacity of 15,200 m³/day.
Priekules NAI is a municipal wastewater treatment plant located in Priekule, a town in the Dienvidkurzemes region of Latvia. The plant serves a population of 492 and operates under Latvia's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 15,200 m³/day and a current discharge volume of 158.68 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local watercourses that drain into the Baltic Sea via the Liepāja Lake or the Venta River basin. The region's aquatic ecosystems benefit from the plant's treatment, which reduces nutrient loading and protects downstream habitats in the Baltic Sea, a sensitive brackish environment.
Environmental context
Priekules NAI discharges treated wastewater into local streams that flow into the Baltic Sea, a semi-enclosed sea with limited water exchange and high sensitivity to nutrient pollution. The plant's secondary treatment helps reduce organic and nutrient loads, supporting the ecological health of downstream rivers and the coastal zone. The region's watershed includes agricultural areas and forests, making nutrient management critical for preventing eutrophication in the Baltic Sea.
Frequently asked questions
Priekules NAI is located at Vaļņu iela, Priekule, Dienvidkurzemes novads, Latvia.
The plant serves a population of 492 people in the town of Priekule and surrounding areas.
The treated effluent is discharged into local watercourses that eventually flow into the Baltic Sea, contributing to the region's water quality management.
As a plant serving fewer than 2,000 people, Priekules NAI is classified as a small agglomeration under the EU UWWTD, which mandates appropriate treatment to protect the environment. Latvia has implemented the directive, requiring secondary treatment for such plants.
For small agglomerations in Latvia, secondary treatment is standard, as required by the EU UWWTD. This biological process effectively reduces organic matter and suspended solids before discharge.
