Wojtowka Wastewater Treatment Plant, Szpitalka, Kuyavian-Pomeranian Voivodeship, Poland

Wojtowka is a wastewater treatment plant located in Szpitalka, a village in the Kuyavian-Pomeranian Voivodeship of Poland. The plant serves a population of 1,354 and operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive for agglomerations of this size. Its designed capacity is 3,000 m³ per day, with an average daily discharge of 193.06 m³. As a secondary treatment facility, Wojtowka removes organic matter and suspended solids through biological processes, meeting the effluent quality standards set by Polish regulations and EU directives. The plant's capacity utilization is low relative to its design, indicating room for future growth or seasonal variations in flow. The treated wastewater is discharged into the local watershed, which ultimately drains into the Vistula River basin and then into the Baltic Sea. The plant plays a role in protecting the region's water quality, particularly the downstream aquatic ecosystems and the sensitive Baltic Sea environment.

The plant discharges into the Vistula River basin, which flows northward through Poland and empties into the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with limited water exchange, making it sensitive to nutrient pollution. Secondary treatment at Wojtowka helps reduce organic load and nutrients, supporting the health of downstream rivers and the coastal marine environment.
