CHELVA Wastewater Treatment Plant, Chelva, Comunitat Valenciana, Spain

The CHELVA wastewater treatment plant is located in Chelva, within the Comunitat Valenciana region of Spain. It serves a population of 2,413, classifying it as a small agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the region's municipal wastewater infrastructure. As a secondary treatment facility, CHELVA meets the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 4,083 m³/day and currently discharges 520.41 m³/day, indicating it operates well below its capacity. This suggests room for future growth or seasonal variability in flow. The treated effluent is discharged into local water bodies that eventually drain into the Mediterranean Sea. The plant plays a key role in protecting the local watershed, including the Turia River basin, from pollution. By providing secondary treatment, it reduces organic load and suspended solids, supporting downstream aquatic life and water quality.

The CHELVA plant discharges into the Turia River basin, which flows eastward to the Mediterranean Sea near Valencia. The river supports diverse aquatic ecosystems and is used for irrigation and recreation. Secondary treatment helps maintain water quality in this sensitive Mediterranean watershed, reducing nutrient loads that could otherwise contribute to eutrophication in coastal waters.
