Overview
VIELHA E MIJARAN wastewater treatment plant serves the Val d'Aran region in Catalunya, Spain. It treats municipal wastewater for a population of approximately 6,342, discharging into local water bodies.
VIELHA E MIJARAN is a wastewater treatment plant located in Vielha e Mijaran, within the Val d'Aran region of Catalunya, Spain. The plant serves a population of around 6,342 residents, providing essential sanitation services for this mountainous area in the Pyrenees. As a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is expected to provide appropriate treatment to protect the sensitive alpine environment. The directive requires secondary treatment for such communities, with potential for more advanced treatment if discharging into sensitive areas. The plant's treated effluent likely flows into local streams that feed the Garona River, which runs through the Val d'Aran and eventually reaches the Atlantic Ocean via the Garonne River in France. This alpine watershed supports diverse aquatic life and is important for regional water quality.
Environmental context
The plant discharges into the Garona River basin, a Pyrenean watershed that flows north into France as the Garonne River, ultimately reaching the Atlantic Ocean. The Val d'Aran is a high-altitude valley with sensitive ecosystems, including cold-water fish species and riparian habitats. Protecting water quality in this headwater region is critical for downstream communities and biodiversity.
