PEGO Wastewater Treatment Plant, Pego, Comunitat Valenciana, Spain

PEGO wastewater treatment plant is located in Pego, a municipality in the Comunitat Valenciana region of eastern Spain. The plant serves a population equivalent of 12,768, placing it in the medium agglomeration category under EU classification. Its location near the Mediterranean coast, within 50 km of the shoreline, makes its discharge practices environmentally significant. As a Spanish facility, PEGO operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with more stringent tertiary treatment if the discharge enters a sensitive area. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a moderate scale. The treated effluent from PEGO likely discharges into local watercourses that flow into the Mediterranean Sea. The region's coastal ecosystems, including seagrass meadows and marine habitats, depend on proper nutrient management to prevent eutrophication. The plant plays a key role in protecting the water quality of the nearby coastline and supporting the ecological health of the Valencian coastal zone.

PEGO plant discharges into the Mediterranean Sea via local streams and irrigation channels in the Marina Alta region. The coastal waters support diverse marine life, including seagrass meadows and fish nurseries, which are sensitive to nutrient loading. Proper treatment helps maintain water quality for tourism and fishing, key economic activities in the area.
