NOVALLASMALON Wastewater Treatment Plant, Novallas, Aragón, Spain

The NOVALLASMALON wastewater treatment plant is located in Novallas, a municipality in the province of Zaragoza, within the autonomous community of Aragón, Spain. This facility serves a small population of 966 residents, reflecting its role in a rural or semi-rural setting. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 2313 cubic meters per day, and it currently discharges an average of 175.09 cubic meters per day, indicating it operates well below its capacity. The treated effluent from NOVALLASMALON is discharged into a local watercourse, which ultimately drains into the Ebro River basin, one of Spain's major river systems. The Ebro River flows eastward into the Mediterranean Sea, supporting diverse aquatic life and agricultural activities along its course. The plant's secondary treatment helps protect the local watershed and downstream ecosystems from pollution.

The plant discharges into a tributary of the Ebro River, which flows through northeastern Spain and empties into the Mediterranean Sea. The Ebro basin supports a variety of aquatic species and is an important resource for irrigation and drinking water. The secondary treatment provided by the plant reduces organic pollutants, helping to maintain water quality in the river system and minimize impacts on downstream habitats.
