The Chiclana wastewater treatment plant is a municipal facility serving the city of Chiclana de la Frontera in the province of Cádiz, Andalucía, Spain. With a population equivalent of 72,726, it falls under the EU classification of a medium agglomeration (10,000-100,000 PE). The plant is situated in the Bahía de Cádiz region, a coastal area with significant tourism and environmental importance. As a Spanish plant serving a medium-sized agglomeration, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum for such populations. The plant's designed capacity is 1. Spanish regulations, transposing the EU directive, mandate that discharges into sensitive areas receive more stringent treatment. The treated effluent from the plant is discharged into the Bay of Cádiz, part of the Atlantic Ocean. This coastal environment supports diverse marine life, including seagrass meadows and fish nurseries, and is an important area for migratory birds. The plant's location within 50 km of the coast underscores the need for effective treatment to protect coastal water quality and the region's ecological and economic resources.

Environmental context

The plant discharges into the Bay of Cádiz, a coastal inlet of the Atlantic Ocean. This area is ecologically sensitive, supporting seagrass beds, shellfish fisheries, and bird populations. The bay receives freshwater from several rivers, including the Guadalete and Iro, and is influenced by tidal flows. Protecting water quality here is critical for tourism, fishing, and biodiversity conservation in the region.
