ROWP SC APA CTTA SA Fil Alba Iulia SRL Teius Wastewater Treatment Plant, Teiuș, Romania

The ROWP SC APA CTTA SA Fil Alba Iulia SRL Teius wastewater treatment plant is located in Teiuș, Alba County, Romania. It serves a population of approximately 1,137 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant is situated on Strada Energiei and operates under the national water management framework. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity of 10,000 m³/day indicates significant headroom for future growth. The actual discharge volume is 49.38 m³/day, suggesting the plant operates well below its design capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Mureș River, a major tributary of the Tisza River, and then into the Danube River before reaching the Black Sea. This downstream connection highlights the plant's role in protecting the broader Danube Basin ecosystem, which supports diverse aquatic life and is an important migratory corridor for fish species.

The plant discharges into the Mureș River basin, which flows into the Tisza River, a key tributary of the Danube River. The Danube ultimately reaches the Black Sea, making this plant part of a vast international watershed. The Mureș River supports diverse aquatic habitats and is important for regional biodiversity, including fish species that migrate within the Danube system. The secondary treatment provided helps reduce organic pollutants and protect downstream water quality.
