Ocsa Szennyviztisztito Telep is a municipal wastewater treatment plant located in Ócsa, a town in Pest county, Central Hungary. The facility serves a population of approximately 16,848 people, placing it in the medium agglomeration category under EU classification. As a Hungarian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Hungary has transposed these requirements into national law, and the plant is subject to compliance monitoring by the relevant water authority. The treated effluent is discharged into local waterways that ultimately drain into the Danube River basin. The Danube flows southward through Hungary and into the Black Sea, making the plant's performance important for downstream water quality in one of Europe's major river systems.
