Overview
PU Limbazu pilsetas KPU serves Limbažu pagasts, Latvia, with a designed capacity of 1.00 cubic meters per day. The plant supports a population of approximately 9,077 and operates under EU wastewater treatment regulations.
PU Limbazu pilsetas KPU is a wastewater treatment plant located in Limbažu pagasts, Latvia, serving a population of about 9,077. The facility is situated in the Limbažu novads region, near the town of Ozolaine. As a municipal plant, it plays a key role in managing wastewater from the local community. The plant has a designed capacity of 1.00 cubic meters per day, indicating a small-scale facility. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have appropriate treatment, typically secondary treatment. It is expected to meet national standards aligned with EU directives. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Gauja River basin. The Baltic Sea is a sensitive marine environment, and nutrient removal is critical to prevent eutrophication. The plant's operation contributes to protecting downstream water quality and the ecological health of the region.
Environmental context
The plant discharges into the Gauja River basin, which flows into the Gulf of Riga and the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Effective wastewater treatment is essential to reduce nitrogen and phosphorus loads that can cause algal blooms and hypoxia. The local watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species.
