Overview
GUENES wastewater treatment plant serves Güeñes, Euskadi, Spain, with a population equivalent of 31,359. The facility has a designed capacity of 1.00 and operates under EU Urban Waste Water Treatment Directive requirements.
The GUENES wastewater treatment plant is located in Güeñes, a municipality in the province of Bizkaia within the autonomous community of Euskadi (Basque Country), Spain. The facility serves a population equivalent of 31,359, classifying it as a medium-sized agglomeration under EU classification. Its location in the Nervión River basin places it within a region known for its industrial history and dense urban development. As a plant in Spain, GUENES operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent discharging into freshwater or estuaries. The plant's designed capacity of 1.00 (likely in cubic meters per day or similar units) supports its service population. Compliance with the directive ensures that treated effluent meets quality standards before discharge. The treated wastewater from GUENES ultimately flows into the Nervión River, which drains into the Cantabrian Sea (Bay of Biscay) via the Bilbao estuary. This water body supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting downstream water quality in a historically industrialized area.
Environmental context
GUENES discharges into the Nervión River basin, which flows through the Bilbao estuary into the Cantabrian Sea (Bay of Biscay). This coastal ecosystem supports diverse marine life and is an important migratory route for fish species. The region's industrial legacy makes effective wastewater treatment critical for maintaining water quality and ecological health in the estuary and adjacent coastal waters.
