ROWP COMPANIA DE APA SOMES Statiunea Muntele Baisorii BAISOARA - Secondary Wastewater Treatment Plant in Muntele Cacovei, Romania

ROWP COMPANIA DE APA SOMES Statiunea Muntele Baisorii BAISOARA is a wastewater treatment plant located in Muntele Cacovei, a locality within Băișoara commune, Cluj County, Romania. The plant serves a small population of 700 residents and operates under secondary treatment, which is the standard for small agglomerations in Romania under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 700 m³/day and currently discharges 16.63 m³/day of treated wastewater. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the regulatory requirements for inland discharge. Romania, as an EU member state, enforces the directive's provisions, which mandate secondary treatment for agglomerations above 2,000 population equivalent, though smaller plants like this one are also expected to comply with national standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Someșul Mic River, a tributary of the Someș River. The Someș River flows into the Tisza River, which then joins the Danube River before reaching the Black Sea. The plant plays a role in protecting the water quality of these downstream water bodies, supporting aquatic life and preventing eutrophication in the sensitive Black Sea basin.

The plant discharges into the Someșul Mic River watershed, which flows into the Someș River, then the Tisza River, and finally the Danube River before reaching the Black Sea. This catchment area supports diverse aquatic ecosystems and is part of a transboundary river system. The Black Sea is a semi-enclosed sea with eutrophication concerns, making nutrient removal from wastewater important for downstream ecological health.
