Overview
Msciwojow wastewater treatment plant in Mściwojów, Poland, provides secondary treatment for a small agglomeration of about 1,588 people, discharging 226.42 m³/day.
The Msciwojow wastewater treatment plant serves the small town of Mściwojów in the Lower Silesian Voivodeship of Poland. It is a municipal facility designed for a capacity of 2,729 m³/day and currently treats an average daily flow of 226.42 m³, indicating it operates well below its design capacity. The plant provides secondary treatment, which is the standard level required under Polish and EU regulations for agglomerations of this size. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for all agglomerations above 2,000 population equivalent (PE) discharging to inland waters. With a population served of 1,588, the plant falls below this threshold but still meets secondary treatment standards, reflecting a proactive approach to water quality. The plant's discharge volume and capacity suggest it is designed to accommodate future growth or seasonal variations. The treated effluent from Msciwojow is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the local watershed from nutrient and organic pollution, supporting the ecological health of downstream rivers and the Baltic Sea ecosystem.
Environmental context
The Msciwojow plant discharges into small streams within the Oder River basin, which flows through western Poland and into the Baltic Sea via the Szczecin Lagoon. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient inputs, making effective wastewater treatment critical. The plant's secondary treatment reduces organic load and helps limit nutrient pollution, supporting the ecological balance of the downstream aquatic environment.

The treated wastewater is discharged into local streams that are part of the Oder River basin, which ultimately flows into the Baltic Sea via the Szczecin Lagoon.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). Although it serves fewer than 2,000 population equivalent, it provides secondary treatment, which is the standard required for larger agglomerations and demonstrates compliance with Polish environmental standards.
In Poland, small wastewater treatment plants serving populations under 2,000 often use secondary treatment technologies such as activated sludge or biological filters to meet national water quality standards, which align with EU directives.
