ROWP CL Slanic Moldova Wastewater Treatment Plant, Slănic-Moldova, Romania

ROWP CL Slanic Moldova is a municipal wastewater treatment plant located in Slănic-Moldova, Bacău County, Romania. The plant serves a population of approximately 35,772, placing it in the medium agglomeration category under EU classification. It is situated inland, away from coastal areas, and its operations are governed by Romanian environmental regulations aligned with EU directives. As a plant serving a medium-sized agglomeration, it is expected to provide at least secondary treatment in accordance with the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires secondary treatment for all discharges from agglomerations of over 2,000 population equivalent, with more stringent requirements for sensitive areas. The plant's treatment processes and capacity details are not publicly available, but it operates within Romania's national regulatory framework, which transposes EU standards. The plant discharges treated wastewater into local watercourses that ultimately drain into the Trotuș River, a tributary of the Siret River, which flows into the Danube River and then the Black Sea. The surrounding region is characterized by mountainous terrain and forests, with the plant playing a key role in protecting the local watershed and downstream ecosystems from pollution.

The plant's treated effluent enters local streams that feed into the Trotuș River, a tributary of the Siret River, which flows into the Danube and eventually the Black Sea. The watershed supports diverse aquatic life and is important for regional biodiversity. The plant's operations help maintain water quality in this ecologically sensitive area, preventing nutrient pollution and protecting downstream habitats.
