Tłuszcz Wastewater Treatment Plant, Tłuszcz | Secondary Treatment in Mazowieckie

The Tłuszcz wastewater treatment plant is located in the town of Tłuszcz, in województwo mazowieckie, Poland. It serves a population of approximately 5,878 residents, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. As a secondary treatment facility, the plant removes biodegradable organic matter and suspended solids, meeting the directive's effluent quality standards. The designed capacity of 5,273.00 thousand m³/year indicates the plant's ability to handle peak flows, while the actual discharge volume of 838.11 thousand m³/year suggests current operations are well within capacity. The plant's operational status is active, serving the local community's wastewater needs. The treated effluent is discharged into a local watercourse that ultimately drains into the Bug River, a major tributary of the Narew River, which flows into the Vistula River and then to the Baltic Sea. This connection to the Baltic Sea catchment underscores the plant's role in protecting downstream aquatic ecosystems, including the sensitive coastal waters of the Baltic Sea, which are vulnerable to nutrient pollution.

The plant discharges into a local stream that flows into the Bug River, part of the Vistula River basin, which drains into the Baltic Sea. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient inputs that can cause eutrophication. The secondary treatment provided by the plant helps reduce organic and nutrient loads, contributing to the protection of downstream water quality and aquatic habitats.
