AGOST Wastewater Treatment Plant, Agost, Comunitat Valenciana, Spain

The AGOST wastewater treatment plant is located in Agost, a municipality in the Comunitat Valenciana region of eastern Spain. The plant serves a population of approximately 6,000 and has a designed capacity of 11,997 cubic meters per day, with a current discharge volume of 478.15 cubic meters per day. As an advanced treatment facility, AGOST goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This level of treatment is typical for plants in sensitive coastal areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires more stringent treatment for discharges into vulnerable zones. The plant's treated effluent is discharged into the local watershed, which drains into the Mediterranean Sea. The coastal location near Alicante means the plant plays a key role in protecting marine water quality and supporting the region's tourism and fishing industries.

The AGOST plant discharges into the Mediterranean Sea via local streams and the Vinalopó River basin. The coastal waters of the Comunitat Valenciana support diverse marine life, including seagrass meadows and fish nurseries. Advanced treatment helps minimize nutrient loading, reducing the risk of eutrophication in this ecologically sensitive coastal zone.
