PAYMOGO Wastewater Treatment Plant, Paymogo, Andalucía, Spain

PAYMOGO is a wastewater treatment plant located in Paymogo, a municipality in the province of Huelva, Andalucía, Spain. The plant serves a small population of approximately 250 people, reflecting its role in a rural community within the El Andévalo region. The facility is currently closed, and its operational status indicates it is no longer active. As a secondary treatment plant, PAYMOGO would have provided biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) of less than 2,000 are subject to less stringent requirements, and secondary treatment is considered appropriate for this scale. The plant's designed capacity of 2,000 m³/day suggests it was built to accommodate a larger population than currently served. The plant's discharge volume is 45.31 m³/day, and the treated effluent would have been released into a local watercourse, likely a tributary of the Guadiana River basin, which flows into the Gulf of Cádiz (Atlantic Ocean). The surrounding area is characterized by Mediterranean climate and rural landscapes, with the plant's operations contributing to the protection of local water quality and downstream ecosystems.

The plant is located inland in the Guadiana River basin, which drains into the Gulf of Cádiz in the Atlantic Ocean. This watershed supports diverse aquatic life and is important for migratory birds. The plant's secondary treatment would have helped reduce nutrient loads and organic pollution, protecting the ecological health of the downstream environment.
