Overview
BASAURBE wastewater treatment plant serves Orozko, Euskadi, Spain, with a designed capacity of 1.00 m³/s. It treats wastewater from a population of 27,167 under EU regulatory standards.
BASAURBE is a wastewater treatment plant located in Orozko, within the Basque Country (Euskadi), Spain. It serves a population of approximately 27,167 people, placing it in the medium agglomeration category under EU classification. The plant is situated near the AP-68 motorway in a region characterized by mountainous terrain and proximity to the Nervión River basin. As a Spanish facility, BASAURBE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 m³/s, indicating it is equipped to handle the wastewater load from the served population. The regulatory framework ensures compliance with discharge standards. The treated effluent from BASAURBE ultimately discharges into the Nervión River, which flows through the Basque Country and into the Cantabrian Sea (Bay of Biscay). This river system supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in the downstream environment, including the Nervión estuary and coastal areas.
Environmental context
BASAURBE discharges into the Nervión River, which flows through the Basque Country and empties into the Cantabrian Sea (Bay of Biscay). The river supports a variety of fish species and provides habitat for migratory birds. The downstream estuary is ecologically sensitive, with tidal marshes and wetlands that contribute to biodiversity. Protecting water quality in this watershed is critical for maintaining the health of the marine environment and local fisheries.
