Overview
ASTUDILLO wastewater treatment plant serves the town of Astudillo in Castilla y León, Spain. It provides secondary treatment for a population of 2,600 and discharges 400 cubic meters of treated wastewater daily.
The ASTUDILLO wastewater treatment plant is located in the municipality of Astudillo, within the province of Palencia in the autonomous community of Castilla y León, Spain. The facility serves a population of approximately 2,600 residents, reflecting its role as a small-scale municipal treatment plant in a rural inland setting. As a secondary treatment plant, ASTUDILLO meets the standard required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in inland areas, ensuring effective removal of organic matter and suspended solids before discharge. The treated effluent is discharged into a local watercourse, contributing to the broader hydrological network of the Duero River basin. This region is characterized by a continental Mediterranean climate, with seasonal variations in flow that influence the dilution capacity of receiving waters. The plant's operation helps protect downstream aquatic ecosystems and supports the ecological health of the Duero catchment.
Environmental context
The ASTUDILLO plant discharges into a tributary of the Pisuerga River, which flows into the Duero River and ultimately reaches the Atlantic Ocean near Porto, Portugal. The Duero basin supports diverse aquatic life, including native fish species such as barbel and nase, and its riparian corridors provide important habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loading and organic pollution, safeguarding water quality in this semi-arid agricultural region.
