ALGAIDA MONTUIRI Wastewater Treatment Plant, Algaida, Mallorca

ALGAIDA MONTUIRI is a wastewater treatment plant located in Algaida, on the island of Mallorca in the Balearic Islands, Spain. It serves a population of 6,566 and has a designed capacity of 7,000 m³/day, with an average discharge volume of 736.80 m³/day. The plant employs advanced treatment processes, meeting high standards for effluent quality. As a facility in the European Union, it operates under the Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size to protect sensitive environments. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The Balearic Islands are ecologically sensitive, with coastal and marine ecosystems that benefit from advanced treatment to minimize nutrient and pollutant loads.

The plant discharges into the Pla de Mallorca basin, which drains into the Mediterranean Sea. The surrounding area includes agricultural land and wetlands that support diverse aquatic life. Advanced treatment helps reduce nutrient inputs, protecting the coastal marine environment from eutrophication and preserving water quality for tourism and biodiversity.
