Overview
ROWP SC APAVIL SA RmValcea is a wastewater treatment plant serving Râmnicu Vâlcea, Romania. It treats wastewater for over 124,000 residents and discharges near the Olt River, a tributary of the Danube.
ROWP SC APAVIL SA RmValcea is a municipal wastewater treatment plant located in the Râureni area of Râmnicu Vâlcea, Romania. Serving a population of approximately 124,227, it is classified as a large agglomeration under Romanian and EU regulations. The plant is situated near the Olt River, which flows southward through the Carpathian foothills. As a large agglomeration, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment in sensitive areas. The Olt River basin is designated as sensitive due to nutrient pollution, so advanced treatment is likely required to reduce nitrogen and phosphorus loads. The plant's treated effluent discharges into the Olt River, which eventually joins the Danube River and flows into the Black Sea. This makes the plant's performance critical for protecting downstream ecosystems, including the Danube Delta, a region of high ecological value that supports diverse aquatic life and migratory bird populations.
Environmental context
The plant discharges into the Olt River, a major tributary of the Danube. The Olt flows through the Carpathian Mountains and the Romanian Plain before joining the Danube near the Bulgarian border. The Danube then empties into the Black Sea via the Danube Delta, an ecologically sensitive area that supports diverse aquatic life and serves as an important migratory corridor for birds. Nutrient loading from upstream sources can contribute to eutrophication in the Black Sea, making effective treatment at this plant essential for regional water quality.
Frequently asked questions
The plant is located in the Râureni area of Râmnicu Vâlcea, Vâlcea County, Romania, near the Olt River.
The plant serves approximately 124,227 residents, classifying it as a large agglomeration under EU regulations.
The treated effluent is discharged into the Olt River, which flows into the Danube and eventually reaches the Black Sea.
As a Romanian plant serving over 100,000 people, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment and likely tertiary treatment in the sensitive Olt River basin.
For large agglomerations in Romania, the EU UWWTD mandates secondary biological treatment. In sensitive areas like the Olt basin, tertiary treatment for nutrient removal (nitrogen and phosphorus) is typically required to protect downstream water bodies.
