Mont-roig del Camp Costa Wastewater Treatment Plant, Mont-roig del Camp, Catalonia

The Mont-roig del Camp Costa wastewater treatment plant is located in Mont-roig del Camp, a municipality in the Baix Camp comarca of Tarragona province, Catalonia, Spain. The plant serves a population of approximately 3,973 residents and has a designed capacity of 1.00, reflecting its role in managing local domestic wastewater. As a small agglomeration in Spain, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuarine areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU regulations for water quality. The treated effluent is discharged into the local environment, ultimately reaching the Mediterranean Sea via the region's drainage network. The plant plays a crucial role in protecting the coastal waters and the nearby beaches, which are important for tourism and local ecosystems. The area's Mediterranean climate and coastal location necessitate effective wastewater management to prevent nutrient pollution and safeguard marine biodiversity.

The plant's treated wastewater flows into the local river system, which drains into the Mediterranean Sea near the Costa Dorada coastline. This coastal area supports diverse marine life and is a popular tourist destination. Effective treatment is essential to prevent eutrophication and protect the ecological health of the sea, which is influenced by both local discharges and broader Mediterranean currents.
