Overview
HERVAS wastewater treatment plant serves the town of Hervás in Extremadura, Spain. It treats wastewater for approximately 7,000 residents under the EU Urban Waste Water Treatment Directive.
HERVAS is a wastewater treatment plant located in Hervás, a town in the province of Cáceres, Extremadura, Spain. The plant serves a population of around 7,000 people, making it a small agglomeration under EU classification. It is situated in the mountainous region of the Ambroz Valley, near the Ambroz River. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 2,000 and 10,000 are required to provide secondary treatment or equivalent. As a plant serving 7,000 people, HERVAS is expected to meet this standard, ensuring effective removal of organic matter and suspended solids before discharge. The treated effluent is likely discharged into the Ambroz River, a tributary of the Alagón River, which flows into the Tagus River (Tajo) and eventually reaches the Atlantic Ocean near Lisbon. The Ambroz Valley is an ecologically sensitive area, supporting diverse aquatic life and serving as a corridor for migratory species. Proper treatment at HERVAS helps protect the water quality of these downstream water bodies.
Environmental context
The HERVAS plant discharges into the Ambroz River, a tributary of the Alagón River, which joins the Tagus River (Tajo) before flowing into the Atlantic Ocean. The Ambroz Valley is a mountainous region with rich biodiversity, including native fish species and riparian vegetation. The plant's operation is crucial for maintaining water quality in this sensitive watershed, which supports local ecosystems and downstream communities.
