Overview
INSKO wastewater treatment plant serves Ińsko, Poland, with secondary treatment for a population of 1,485. It discharges 211.74 m³/day of treated wastewater, with a designed capacity of 8,624 m³/day.
The INSKO wastewater treatment plant is located in Ińsko, a town in the West Pomeranian Voivodeship of northwestern Poland. It serves a population of approximately 1,485 residents, providing secondary treatment as part of the municipal wastewater infrastructure. The plant has a designed capacity of 8,624 m³/day and currently discharges 211.74 m³/day of treated effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, which INSKO meets. The directive also mandates appropriate collection systems and treatment to protect receiving waters. The treated wastewater is discharged into local watercourses that ultimately drain into the Baltic Sea via the Oder River basin. The plant plays a key role in protecting the region's aquatic ecosystems, including the nearby Ińsko Lake and downstream environments, by reducing nutrient and pollutant loads.
Environmental context
The plant discharges into local streams that feed into the Ina River, a tributary of the Oder River, which flows into the Szczecin Lagoon and then the Baltic Sea. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient inputs. The secondary treatment at INSKO helps reduce organic matter and nutrients, supporting the health of downstream waters and the coastal marine environment.
