Nagykanizsa Szennyviztisztito Telep - Wastewater Treatment Plant in Nagykanizsa, Hungary

Nagykanizsa Szennyviztisztito Telep is a municipal wastewater treatment plant located in Nagykanizsa, a city in Zala County, Hungary. The facility serves a population of approximately 69,098, placing it in the medium-to-large agglomeration category under EU classification. It is situated in the Nyugat-Dunántúl region, an area characterized by a mix of urban and agricultural landscapes. As a plant serving over 10,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For agglomerations of this size in sensitive areas, tertiary treatment may be mandated. The plant's designed capacity is 1. 00 (likely in thousands of cubic meters per day), indicating a scale appropriate for its population served. The regulatory framework ensures compliance with discharge standards. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the Zala River and Lake Balaton watershed, a region of ecological importance for aquatic biodiversity and water quality. Proper treatment helps prevent nutrient pollution and supports the health of downstream ecosystems.

The plant discharges into the Zala River system, which flows into Lake Balaton, Central Europe's largest lake. Lake Balaton is a shallow, nutrient-sensitive water body that supports diverse aquatic life and is a major recreational resource. Downstream, the Zala River connects to the Danube River, which drains into the Black Sea. The plant's operations are critical for controlling nutrient loads and maintaining water quality in this ecologically important watershed.
