Overview
SAN PANTALEON wastewater treatment plant serves a population of 238,900 in Spain. It is located near the coast and operates under the EU Urban Waste Water Treatment Directive.
SAN PANTALEON is a wastewater treatment plant in Spain, serving a population of 238,900. The plant is situated near the coast, reflecting its role in managing municipal wastewater for a large agglomeration. As a Spanish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 15,000 population equivalent and tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale. The plant discharges treated water into the local watershed, ultimately reaching the Bay of Biscay. This coastal discharge requires compliance with stringent standards to protect marine ecosystems. The surrounding area supports diverse aquatic life and is part of a broader regional drainage network that includes rivers flowing from the Cantabrian Mountains to the Atlantic Ocean.
Environmental context
The plant's treated effluent flows into the Cantabrian Sea (Bay of Biscay) via local rivers. This coastal region supports important fisheries and marine biodiversity. The watershed includes mountainous terrain and agricultural areas, contributing to seasonal flow variations. The discharge must meet EU standards to prevent eutrophication and protect sensitive coastal habitats.
Frequently asked questions
SAN PANTALEON is located in Spain, near the coast at coordinates 43.475 N, -3.416 W. It serves a large agglomeration of 238,900 people.
The plant discharges treated wastewater into local rivers that flow into the Cantabrian Sea (Bay of Biscay). As a coastal plant, it must meet strict EU standards to protect marine environments.
The plant helps protect rivers in the Cantabrian watershed, which drain from the Cantabrian Mountains to the Atlantic Ocean. These rivers support diverse aquatic life and are important for regional ecology.
As a plant serving over 150,000 people, SAN PANTALEON is classified as a large agglomeration under the EU UWWTD. It is required to provide at least secondary treatment, and likely tertiary treatment if discharging to sensitive coastal areas.
For a plant of this size in Spain, typical treatment includes secondary biological treatment (activated sludge) and often tertiary treatment (nutrient removal, disinfection) to meet EU standards for coastal discharge.
