Kasinka Mala Wastewater Treatment Plant, Szaflary, Poland

Kasinka Mala is a wastewater treatment plant located in Szaflary, within the małopolskie province of Poland. It serves a population of approximately 3,023 people, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 9,372 m³/day and a current discharge volume of 431.03 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The treated effluent is discharged into local water bodies that eventually drain into the Vistula River basin, which flows into the Baltic Sea. The plant's advanced treatment helps protect downstream ecosystems, including rivers and the Baltic Sea, from nutrient pollution and other contaminants. This is particularly important given the ecological sensitivity of the Baltic Sea, which is prone to eutrophication.

The plant discharges into local streams that are part of the Vistula River basin, ultimately flowing into the Baltic Sea. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient enrichment from wastewater discharges. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, supporting the health of downstream aquatic ecosystems and contributing to regional efforts to combat eutrophication.
