Polgardi Szennyviztisztito Telep - Advanced Wastewater Treatment in Polgárdi, Hungary

Polgardi Szennyviztisztito Telep is an advanced wastewater treatment plant located in Polgárdi, a town in Fejér County, Hungary. The plant serves a population of approximately 6,200 residents, making it a medium-sized facility within the region. It is situated near the M7 motorway, in the Közép-Dunántúl region, and operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,125 m³/day and a current discharge volume of 730.87 m³/day, the facility operates well below its maximum capacity, indicating room for future growth. As an advanced treatment plant, it meets stringent effluent quality standards required for sensitive areas. The treated wastewater is discharged into the local watershed, which ultimately drains into Lake Balaton, one of Europe's largest freshwater lakes and a vital ecological and recreational resource. The plant plays a crucial role in protecting the lake's water quality by reducing nutrient loads that could cause eutrophication. Its coastal proximity (within 10 km of the lake) underscores the importance of its advanced treatment capabilities.

The plant discharges into the watershed that feeds Lake Balaton, a large shallow lake in western Hungary. Lake Balaton is a sensitive ecosystem prone to algal blooms from nutrient pollution. The advanced treatment at this plant helps control phosphorus and nitrogen inputs, supporting the lake's biodiversity and recreational value. The water eventually flows through the Sió Canal into the Danube River, reaching the Black Sea.
