Overview
Aizputes NAI is an advanced wastewater treatment plant serving Aizpute, Latvia. It treats wastewater for approximately 4,086 people with a designed capacity of 7,980 m³/day.
Aizputes NAI is a municipal wastewater treatment plant located in Aizpute, a town in the Dienvidkurzemes region of Latvia. The plant serves a population of around 4,086 and is designed to handle a capacity of 7,980 cubic meters per day, with a current discharge volume of 545.48 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. This level of treatment is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream environments, including coastal ecosystems.
Environmental context
The plant discharges into the local river system, which flows into the Baltic Sea via the Liepāja Lake or directly to the coast. 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 nitrogen and phosphorus loads, mitigating eutrophication risks in the sea.
