Overview
The Melilla wastewater treatment plant serves approximately 100,000 people in the Spanish autonomous city of Melilla on the Mediterranean coast. It is located near the coast and operates under Spanish and EU wastewater regulations.
The Melilla wastewater treatment plant is a municipal facility serving the city of Melilla, a Spanish enclave on the Mediterranean coast of North Africa. The plant serves a population of approximately 100,000, classifying it as a large agglomeration under EU regulations. Its location on the southern shore of the Mediterranean Sea places it in a sensitive coastal environment. As a plant serving over 100,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The Mediterranean coastal zone is designated as a sensitive area under the directive, necessitating advanced treatment to protect marine water quality. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure. The treated effluent is discharged into the Mediterranean Sea, which is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution. The plant plays a critical role in protecting coastal ecosystems, including seagrass meadows and marine biodiversity, from eutrophication and contamination. Its operation is essential for maintaining bathing water quality and supporting local fisheries and tourism.
Environmental context
The plant discharges into the Mediterranean Sea, a semi-enclosed basin with limited tidal flushing, making it sensitive to nutrient loading. The coastal waters near Melilla support diverse marine life, including seagrass habitats and migratory fish species. Protecting this environment requires advanced treatment to reduce nitrogen and phosphorus, as mandated by the EU Urban Waste Water Treatment Directive for sensitive areas.
Frequently asked questions
The plant is located in Melilla, a Spanish autonomous city on the Mediterranean coast of North Africa, at Carretera del Dique Sur.
The plant serves approximately 100,000 people, classifying it as a large agglomeration under EU regulations.
The treated effluent is discharged into the Mediterranean Sea, which is a sensitive area requiring advanced treatment to protect marine ecosystems.
As a plant serving over 100,000 people in a coastal sensitive area, it must meet tertiary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC) to reduce nutrients and protect the Mediterranean.
Plants of this scale in Spain typically employ secondary biological treatment followed by tertiary processes such as nutrient removal, especially in coastal sensitive areas, to comply with EU directives.
