MEDINA DE POMAR Wastewater Treatment Plant, Medina de Pomar, Spain

MEDINA DE POMAR is a wastewater treatment plant located in Medina de Pomar, a municipality in the province of Burgos, Castilla y León, Spain. The plant serves a population of approximately 36,000 people, classifying it as a medium agglomeration under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with European standards. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Mediterranean Sea via the Ebro River basin. The plant plays a key role in protecting water quality in the region, supporting aquatic ecosystems and downstream water uses.

The plant discharges into the Ebro River basin, which flows into the Mediterranean Sea. The Ebro River supports diverse aquatic life and is an important ecological corridor in northeastern Spain. The Mediterranean coastal zone is sensitive to nutrient pollution, making effective wastewater treatment critical for preventing eutrophication and protecting marine biodiversity.
