RIAZA is a wastewater treatment plant located in the Común de Sepúlveda y Riaza area, within the province of Segovia, Castilla y León, Spain. The plant serves a population of approximately 8,248 people, making it a medium-sized facility in the region. Its address on the N-110 road in Gomeznarro places it in a rural setting within the Comunidad de Villa y Tierra de Sepúlveda. As a Spanish wastewater treatment plant, RIAZA operates under the national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 2,000 and 10,000, the directive requires secondary treatment or equivalent. It is expected to comply with these standards. The treated effluent from RIAZA is discharged into a local watercourse that eventually drains into the Duero River basin, one of the major river systems in the Iberian Peninsula. The Duero flows westward through Spain and Portugal, emptying into the Atlantic Ocean at Porto. The plant plays a role in protecting the local aquatic environment and downstream water quality in the Duero watershed.
Environmental context
RIAZA discharges into a tributary of the Duero River, which flows through the Castilla y León region and ultimately reaches the Atlantic Ocean. The Duero basin supports diverse aquatic life and is an important agricultural and ecological corridor. The plant's operations help maintain water quality in this sensitive watershed, which is subject to EU water framework directives.
