Overview
CASAQUEMADA wastewater treatment plant serves San Fernando de Henares in the Comunidad de Madrid, Spain. It handles a population equivalent of 147,498 under the EU Urban Waste Water Treatment Directive.
CASAQUEMADA is a wastewater treatment plant located in San Fernando de Henares, within the Comunidad de Madrid, Spain. The facility serves a population equivalent of 147,498, classifying it as a large agglomeration under EU regulations. Its location in the Madrid metropolitan area places it within a densely populated urban and industrial region. As a plant of this scale in Spain, CASAQUEMADA operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for all agglomerations above 2,000 population equivalent and tertiary treatment for those discharging into sensitive areas. The plant's treatment processes are expected to meet these standards to protect the receiving environment. The treated effluent from CASAQUEMADA likely discharges into the Henares River, a tributary of the Jarama River, which flows into the Tagus River and ultimately reaches the Atlantic Ocean near Lisbon. The Tagus basin supports diverse aquatic life and is an important water resource for central Spain and Portugal.
Environmental context
The plant discharges into the Henares River, part of the Tagus River basin, which drains into the Atlantic Ocean. The Tagus is one of the longest rivers in the Iberian Peninsula and supports a variety of fish species, including migratory fish like eels and lampreys. The river's ecological health is influenced by urban and agricultural runoff, making effective wastewater treatment critical for maintaining water quality and biodiversity in this transboundary basin.
