Environmental context
The plant discharges into the local watershed within the Nissan River basin, which flows into the Kattegat strait and eventually the Baltic Sea. The Baltic Sea is a semi-enclosed sea highly sensitive to nutrient pollution, making advanced treatment crucial for reducing nitrogen and phosphorus loads. The surrounding area features mixed forest and agricultural land, contributing to diffuse pollution sources that the plant helps mitigate.
