VALENCIA MASSARROJOS Wastewater Treatment Plant, València, Spain

VALENCIA MASSARROJOS is a former wastewater treatment plant located in the Massarrojos district of València, in the Comunitat Valenciana region of Spain. The plant served the northern suburbs of València and was designed with a capacity of 1500 cubic meters per day. It is now closed, and its treatment responsibilities have likely been transferred to other facilities in the area. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into sensitive areas. Although the plant is closed, the regulatory framework for wastewater treatment in Spain is governed by this directive, which mandates secondary treatment for agglomerations of over 2000 population equivalent and tertiary treatment for sensitive areas. The plant's proximity to the Mediterranean Sea (within 10 km) means that treated effluent would have discharged into coastal waters. The region's drainage ultimately flows into the Mediterranean, which supports diverse marine ecosystems.

The plant is located in the Turia River basin, which drains into the Mediterranean Sea near València. The coastal waters of the València region support seagrass meadows and important fisheries. Although the plant is closed, its historical discharges would have affected the marine environment. The area is ecologically sensitive due to its proximity to the Albufera Natural Park, a coastal lagoon and wetland of international importance for birdlife.
