Gestalgar Wastewater Treatment Plant: Serving Gestalgar, Comunitat Valenciana, Spain

The Gestalgar wastewater treatment plant is located in the municipality of Gestalgar, in the province of Valencia, within the Comunitat Valenciana region of Spain. It serves a population of approximately 975 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 2,000 m³/day and an average daily flow of 148.13 m³, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local watercourse that ultimately drains into the Mediterranean Sea via the Turia River basin. The plant plays a key role in protecting the region's water resources and downstream ecosystems, including coastal areas of the Valencian Community.

The plant discharges into a tributary of the Turia River, which flows eastward through the province of Valencia and empties into the Mediterranean Sea near the city of Valencia. The Turia River supports diverse aquatic life and is an important ecological corridor in the region. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality and the sensitive coastal environment of the Mediterranean.
