Detek Szennyviztisztito Telep - Secondary Wastewater Treatment Plant in Detek, Hungary

Detek Szennyviztisztito Telep is a municipal wastewater treatment facility located in the village of Detek, in the Borsod-Abauj-Zemplen county of northern Hungary. The plant serves a small population of 260 residents, reflecting the rural character of the area. It operates as part of Hungary's national wastewater infrastructure under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is appropriate for small agglomerations under EU regulations. It has a designed capacity of 670 cubic meters per day and currently treats an average daily flow of 30.65 cubic meters, indicating significant spare capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that drain into the Hernad River basin, eventually reaching the Tisza River and the Danube River before flowing into the Black Sea. The plant plays a key role in protecting the local aquatic environment from untreated sewage, supporting water quality in the region's streams and rivers.

The plant discharges treated wastewater into small streams that are part of the Hernad River catchment, a tributary of the Tisza River. The Tisza flows into the Danube, which ultimately reaches the Black Sea. The local watershed supports diverse aquatic life and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water bodies from eutrophication.
