LA LLOSA Wastewater Treatment Plant, la Llosa, Comunitat Valenciana, Spain

LA LLOSA is a wastewater treatment plant located in la Llosa, a municipality in the province of Castellón, Comunitat Valenciana, Spain. The plant serves a population of approximately 865 residents and operates with a designed capacity of 2,500 cubic meters per day. It is situated near the Mediterranean coast, within 10 kilometers of the shoreline. The plant provides secondary treatment, which is the standard biological treatment required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. For smaller agglomerations like la Llosa (population under 2,000), the directive mandates appropriate treatment to ensure the receiving environment is protected. The plant's discharge volume is reported as 159.85 cubic meters per day, indicating a utilization rate well below its design capacity. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Mediterranean Sea. The coastal waters in this region support diverse marine life and are important for tourism and fisheries. The plant plays a key role in protecting the coastal environment from untreated wastewater, helping to maintain water quality standards along the Valencian coast.

The plant discharges into the Mediterranean Sea via local streams and drainage channels. The coastal waters of Comunitat Valenciana support seagrass meadows, fish nurseries, and migratory bird populations. As a coastal facility, the plant helps prevent nutrient and pathogen pollution that could harm marine ecosystems and recreational beaches.
