LA MALAHA Wastewater Treatment Plant, Gabia Grande, Andalucía

LA MALAHA is a wastewater treatment plant located in Gabia Grande, within the municipality of La Malahá, in the province of Granada, Andalucía, Spain. It was designed to serve a population of 2,671 and has a designed capacity of 3,000 cubic meters per day. The plant is currently closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in freshwater areas, ensuring removal of organic matter and suspended solids. The treated effluent was discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Guadalfeo River basin. The region's semi-arid climate makes water quality management crucial for downstream ecosystems and agricultural reuse.

The plant's discharge flows into the Guadalfeo River basin, which drains into the Mediterranean Sea near the coast of Granada. This coastal area supports diverse marine life and is important for local fisheries. The semi-arid climate means that treated wastewater can be a valuable resource for irrigation, but also requires careful management to prevent nutrient pollution in downstream water bodies.
