Brckovljani Bozjakovina Wastewater Treatment Plant, Općina Brckovljani, Croatia

Brckovljani Bozjakovina is a wastewater treatment plant located in the municipality of Općina Brckovljani, within the Zagreb County of Croatia. The plant was designed to serve the local population with a capacity of 8,400 cubic meters per day, reflecting its role in managing municipal wastewater in this inland region. The plant provided secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. As a Croatian facility, it operated under national regulations aligned with EU standards, ensuring compliance with effluent quality requirements for inland freshwater discharge. The treated effluent from the plant would have been discharged into local watercourses that drain into the Sava River basin, ultimately reaching the Danube River and the Black Sea. The plant's operation was important for protecting the local watershed and downstream ecosystems from untreated wastewater pollution.

The plant is situated in the Sava River basin, with treated effluent likely discharged into tributaries that flow into the Sava River, a major tributary of the Danube. The Danube then carries water to the Black Sea. This inland location means the plant's discharge affects freshwater ecosystems, supporting aquatic life and maintaining water quality for downstream communities.
