ARAS DE LOS OLMOS Wastewater Treatment Plant, Aras de los Olmos, Spain

ARAS DE LOS OLMOS is a wastewater treatment plant located in Aras de los Olmos, a municipality in the La Serranía comarca of Valencia, within the Comunitat Valenciana region of Spain. The plant serves a population of 1,460 and has a designed capacity of 2,000 cubic meters per day, with a current discharge volume of 131.02 cubic meters per day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological oxidation and sedimentation to remove organic matter and suspended solids before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the region's water resources and downstream ecosystems, including the Turia River basin and the coastal environment of the Valencian Community.

The plant discharges into the Turia River basin, which flows eastward through the province of Valencia and empties into the Mediterranean Sea near the city of Valencia. The downstream environment includes ecologically sensitive coastal areas and agricultural zones that depend on water quality. The secondary treatment provided helps reduce nutrient and organic loads, supporting the health of the riverine and marine ecosystems.
