Overview
Lassan wastewater treatment plant in Mecklenburg-Vorpommern, Germany, serves 1,901 people with advanced treatment. It discharges 481.10 m³/day and has a designed capacity of 2,800 m³/day.
The Lassan wastewater treatment plant is located in the town of Lassan, in the Vorpommern-Greifswald district of Mecklenburg-Vorpommern, Germany. It serves a population of approximately 1,901 residents and is situated near the Peenestrom river system. The plant is currently closed, but its infrastructure reflects the scale of a small agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,800 m³/day, with an average discharge volume of 481.10 m³/day. As a coastal facility within 10 km of the Baltic Sea, the advanced treatment level helps protect sensitive marine environments. The treated effluent from the plant discharges into the Peenestrom, a strait connecting the Szczecin Lagoon to the Baltic Sea. This water body supports diverse aquatic life and is part of a larger estuarine ecosystem. The plant's advanced treatment contributes to maintaining water quality in this ecologically important coastal region.
Environmental context
The plant's treated effluent flows into the Peenestrom, a strait that connects the Szczecin Lagoon to the Baltic Sea. This area is part of a dynamic estuarine environment that supports fish spawning, migratory birds, and diverse aquatic vegetation. The Baltic Sea itself is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient inputs. Advanced treatment at this plant helps reduce nutrient loading, protecting the local watershed and downstream marine habitats.
