Gminna Oczyszczalnia Sciekow Komunalnych w Bolimowie - Secondary Wastewater Treatment in Bolimowska Wieś

Gminna Oczyszczalnia Sciekow Komunalnych w Bolimowie is a municipal wastewater treatment plant located in Bolimowska Wieś, within the gmina of Bolimów in the Skierniewice district of Łódź Voivodeship, Poland. The plant serves a small community of 983 residents, reflecting its role in rural wastewater management. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. With a designed capacity of 2750 m³/day and an actual discharge volume of 140.16 m³/day, the plant operates well below its capacity, indicating potential for future growth. Under Polish regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to provide appropriate treatment to protect local water quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Bzura River, a tributary of the Vistula River. The Vistula flows northward into the Baltic Sea, making this plant part of a larger network of facilities safeguarding the Baltic Sea from nutrient pollution. The surrounding area is predominantly agricultural, and the plant plays a key role in preventing eutrophication in downstream water bodies.

The plant discharges into the local drainage network that feeds the Bzura River, a right-bank tributary of the Vistula. The Vistula River flows through central Poland and empties into the Baltic Sea via the Gdańsk Bay. The Baltic Sea is a semi-enclosed sea sensitive to nutrient inputs, and secondary treatment helps reduce organic and nutrient loads that could contribute to algal blooms and hypoxia. The plant's location in an agricultural region means it also helps protect groundwater and local streams from contamination.
