What Acosol does

Acosol, S.A. is a publicly owned water utility company founded in 1994 and wholly controlled by the Mancomunidad de Municipios de la Costa del Sol Occidental, a consortium of eleven municipalities in the province of Málaga, Spain. The company manages the complete water cycle—abstraction, treatment, high-level and low-level distribution, sanitation, wastewater treatment, and water regeneration—on an exclusive franchise basis across Benahavís, Benalmádena, Casares, Estepona, Fuengirola, Istán, Manilva, Marbella, Mijas, Ojén, and Torremolinos, serving approximately 1 million permanent residents that rise to 1.4 million during the summer tourist season.

The company's core infrastructure includes the ETAP Río Verde water treatment plant (capacity of 2.3 m³/second, in operation since 1972), the EDAM Marbella seawater desalination plant (56 million liters per day, commissioned in 1997 and the only desalination facility in Málaga province), seven wastewater treatment plants (EDARs) with the largest serving a population equivalent of over 400,000 inhabitants, and more than 90 kilometers of sewer network spanning from Manilva to Torremolinos. Acosol operates ISO 9001-certified laboratories performing over 140,000 water quality analyses per year and is pursuing ISO 17025 accreditation for its wastewater laboratories. Its Agua 360 digital transformation platform, funded by €3.29 million from Spain's PERTE Digitalización del Ciclo del Agua program, is deploying 51 digital actions including GIS, SCADA web data management, Big Data analytics, asset management, and cybersecurity modules. R&D initiatives include the LIFE Matrix managed aquifer recharge project (aiming to increase underground water resources by 15% and reduce greenhouse gas emissions by 99%) and the TRIATHLON AI-based water quality monitoring project.

Acosol generates revenue through tiered monthly tariffs covering fixed service charges and variable consumption charges for domestic, industrial, commercial, construction, and official-body use cases, plus special surcharges for elevation and desalination. Additional revenue streams include transaction-based sales of regenerated wastewater for irrigation of golf courses and public green spaces—a practice developed over 20 years—and public infrastructure investment funded by the European Investment Bank (€175 million approved financing, the largest EIB water project in Spain for 2025) and EU NextGenerationEU funds. The company employs more than 400 people and is led by Consejera Delegada Matilde Mancha, with Marcelino Manzanares serving as Director of Operations.
