POBLA DE LILLET LA Wastewater Treatment Plant, la Pobla de Lillet, Catalunya

POBLA DE LILLET LA is a wastewater treatment facility located in la Pobla de Lillet, a municipality in the Berguedà region of Barcelona, Catalunya, Spain. The plant serves a small population of 530 residents, reflecting its role in a rural or semi-rural community. As part of Spain's wastewater infrastructure, it contributes to local sanitation and environmental protection. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. It has a designed capacity of 3,500 m³/day and currently treats an average daily volume of 561.55 m³, indicating significant spare capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to provide appropriate treatment, and the advanced level here exceeds the minimum secondary treatment standard. The treated effluent is discharged into the local watershed, which ultimately drains into the Llobregat River basin. The Llobregat River flows through Catalunya and into the Mediterranean Sea near Barcelona. The plant's advanced treatment helps protect the river's water quality and supports downstream ecosystems, including aquatic life and agricultural uses.

The plant discharges into the Llobregat River basin, which flows through the Catalan pre-coastal range and into the Mediterranean Sea. This watershed supports diverse aquatic habitats and is important for regional water supply and irrigation. The advanced treatment helps minimize nutrient and pollutant loads, protecting downstream ecological communities and reducing the risk of eutrophication in coastal waters.
