Molnari Szennyviztisztito Telep - Secondary Wastewater Treatment in Molnári, Hungary

Molnari Szennyviztisztito Telep is a municipal wastewater treatment plant located in Molnári, a village in Zala County, Hungary. The plant serves a population of 650 and has a designed capacity of 900 cubic meters per day, with an average discharge volume of 76.62 m³/day. It operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. As a small-scale facility, it meets the regulatory standards set by Hungarian water authorities for communities under 2,000 population equivalent. The treatment process ensures that effluent quality complies with national and EU discharge limits before release. The treated wastewater is discharged into local watercourses that drain into the Mura River, a tributary of the Drava, which flows into the Danube and ultimately the Black Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the Mura-Drava-Danube basin, an ecologically sensitive area that hosts diverse species and serves as an important migratory corridor.

The plant's effluent enters local streams that flow into the Mura River, a major tributary of the Drava. The Drava joins the Danube near Osijek, Croatia, and the Danube carries water to the Black Sea. This watershed supports diverse aquatic ecosystems, including fish spawning grounds and riparian habitats. The region is part of a transboundary river system where water quality management is critical for biodiversity and downstream communities.
