Overview
HORMILLA wastewater treatment plant serves the town of Hormilla in La Rioja, Spain. It treats wastewater from a population of approximately 1,122 people.
The HORMILLA wastewater treatment plant is located in the municipality of Hormilla, in the autonomous community of La Rioja, Spain. The plant serves a small population of around 1,122 residents, reflecting its role in a rural or semi-rural setting. As a facility in Spain, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets treatment standards based on population equivalents and receiving water sensitivity. For a plant serving fewer than 2,000 people, the EU directive requires appropriate treatment to meet local environmental objectives. Plants of this scale in Spain typically employ secondary treatment or equivalent technologies to reduce organic load and nutrients before discharge. The plant's design capacity and operational status are consistent with small community infrastructure, and it is expected to comply with Spanish water quality regulations. The treated effluent from HORMILLA is discharged into a local watercourse, likely a tributary of the Ebro River basin, which is the major river system in La Rioja. The Ebro River flows eastward into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural irrigation along its course. The plant's operation helps protect local streams and downstream water quality in this wine-producing region.
Environmental context
The plant discharges into a local stream that is part of the Ebro River basin, one of Spain's largest watersheds. The Ebro River flows into the Mediterranean Sea, supporting ecologically sensitive delta habitats and coastal fisheries. The region's semi-arid climate makes water quality management critical for both ecological health and agricultural use, particularly for vineyards in La Rioja.
