Iecavas c NAI Wastewater Treatment Plant, Iecava, Latvia

Iecavas c NAI is an advanced wastewater treatment plant located in Iecava, a town in Bauskas novads, Latvia. The plant serves a population of approximately 3,306 residents, making it a small-scale facility within the country's wastewater infrastructure. Its location in the central part of Latvia places it within the broader Lielupe River basin, which drains into the Baltic Sea. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,000 cubic meters per day and a current discharge volume of 385.62 cubic meters per day, the facility operates well below its capacity, indicating room for future growth. As a Latvian facility, it operates under national regulations that align with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for sensitive areas. The treated wastewater from Iecavas c NAI is discharged into local watercourses that eventually flow into the Lielupe River and then into the Baltic Sea. This makes the plant's advanced treatment crucial for protecting the sensitive Baltic Sea ecosystem from nutrient pollution. The facility contributes to maintaining water quality in the region's rivers and supports the ecological health of downstream environments.

The plant discharges into local streams that are part of the Lielupe 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 inputs. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, mitigating eutrophication risks in downstream coastal waters.
