Kethely Szennyviztisztito Telep - Wastewater Treatment Plant in Kethely, Hungary

Kethely Szennyviztisztito Telep is a municipal wastewater treatment plant located in Kethely, in the Dél-Dunántúl region of Hungary. The facility serves a population of approximately 18,000, classifying it as a medium agglomeration under EU guidelines. Its location near Lake Balaton places it in a sensitive area requiring advanced treatment. As a Hungarian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. For plants in sensitive areas like the Lake Balaton catchment, tertiary treatment is typically required to reduce nutrient loads and protect water quality. The plant's treated effluent likely discharges into a tributary of the Balaton basin, ultimately reaching Lake Balaton, Central Europe's largest lake. This water body supports diverse aquatic life and is a key recreational and ecological resource. Proper treatment is essential to prevent eutrophication and maintain the lake's ecological health.

The plant is situated in the Lake Balaton catchment, a sensitive watershed that drains into the lake via small streams and canals. Lake Balaton is a shallow, nutrient-sensitive lake that supports diverse aquatic ecosystems and is a major tourist destination. Downstream, the lake's outflow feeds the Sió Canal, which connects to the Danube River, eventually reaching the Black Sea. Protecting the lake from nutrient pollution is critical to prevent algal blooms and maintain water quality.
