Overview
ROWP SC Apa Serv Valea Jiului SA Petrosani Danutoni is a wastewater treatment plant serving Petroșani, Romania. It handles a population equivalent of 106,602 under the EU Urban Waste Water Treatment Directive.
ROWP SC Apa Serv Valea Jiului SA Petrosani Danutoni is a wastewater treatment plant located in Petroșani, Hunedoara County, Romania. The facility serves a population equivalent of 106,602, classifying it as a large agglomeration under EU regulations. It is situated in the Jiu Valley, a region known for its mining history and mountainous terrain. As a plant serving over 100,000 people, it is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The Jiu Valley is part of the Jiu River basin, which flows into the Danube and eventually the Black Sea, making nutrient removal a likely requirement to protect downstream ecosystems. The plant discharges into the Jiu River, a tributary of the Danube. The downstream environment includes the Danube Delta Biosphere Reserve, a critical wetland ecosystem. Proper treatment at this plant helps reduce nutrient and pollutant loads entering the Danube and Black Sea, supporting aquatic biodiversity and water quality.
Environmental context
The plant discharges into the Jiu River, which flows into the Danube River and ultimately the Black Sea. The Danube Delta is a major ecological zone supporting diverse aquatic life, including migratory fish and bird species. Nutrient pollution from upstream sources can contribute to eutrophication in the Black Sea, making advanced treatment important for this large agglomeration.
