This commitment is articulated through a cross-cutting strategy that integrates efficient water management, reduction of energy consumption, incorporation of renewable energies and the constant modernization of its infrastructure.
To carry out these actions, we have an ambitious investment plan of close to 350 million euros, aimed at modernizing hydraulic infrastructure, optimizing water resources and reducing the environmental impact in all the municipalities of the Western Costa del Sol.
Acosol’s business model is committed to the circular economy through the use of resources and the generation of clean energy.
Among the most relevant initiatives:
Advanced research to promote systems that further improve the quality of drinking water.
Acosol is carrying out a major plan to modernize water infrastructure, aiming to make it more efficient, resilient, and environmentally friendly.
In addition, renovation work is being carried out on sanitation networks and key facilities, enhancing safety, reducing losses, and improving the quality of regenerated water.
In line with energy transition goals, Acosol has stepped up the integration of renewable energy sources into its facilities, with a particular focus on solar photovoltaic energy.
The installation of solar plants on water infrastructure enables:
These initiatives have been progressively rolled out across various facilities, consolidating an energy model that is more sustainable and aligned with European decarbonization policies.
At Acosol, we take part in various R&D projects alongside other organizations, companies, and institutions. One such example is Life Matrix—an initiative led by Cetaqua Andalucía, with the participation of Cetaqua Barcelona, Acosol, and the University of Málaga—which aims to increase available groundwater resources by 15% and reduce energy consumption and greenhouse gas emissions by 99%.
We are also participating in the Triathlon project (TRIhAlomeTHanes controL thrOugh AI-based techNologies)—alongside the University of Málaga, Aguas de Huelva, and Aguas de Benahavís—which aims to facilitate the management of drinking water distribution networks, specifically regarding the formation of disinfection by-products such as trihalomethanes (THMs).
El servicio de laboratorios constituye un pilar fundamental en la gestión eficiente y segura del ciclo integral del agua. A través de análisis rigurosos y controles continuos, los laboratorios garantizan la calidad del agua en todas sus fases, desde el abastecimiento hasta el tratamiento y la depuración.
Laboratory services constitute a fundamental pillar in the efficient and safe management of the integrated water cycle. Through rigorous analysis and continuous monitoring, laboratories ensure water quality at every stage, from supply to treatment and purification.
Precision, technological innovation, and the expertise of technical staff enable the laboratory service to function not merely as a control system, but also as a key tool for continuous improvement. This optimizes processes, increases operational efficiency, and reinforces the commitment to sustainability.
In the water supply process, our control system spans from the source intake right to the consumer’s tap, powered by a network of automated monitoring stations linked to our central remote control infrastructure.
Similarly, wastewater quality is secured through purification processes, followed by regeneration.
The two laboratories that monitor drinking water, located at the Desalination Plant and at the Río Verde Drinking Water Treatment Plant (DWTP), have been certified according to the UNE EN ISO 9001 standard since 2004, performing more than 60,000 analyses annually.
For the treated wastewater, there are five laboratories: the central sanitation laboratory, at the Wastewater Treatment Plant (WWTP) of La Víbora (Marbella), and those located at the stations of Arroyo de la Miel (Benalmádena), Cerros del Águila (Mijas – Fuengirola), Estepona and Manilva; these locations monitor the quality of the treated water before its discharge into the sea and that of the regenerated water before its delivery to high volume users that use it for irrigation.
These five laboratories, carry out more than 80,000 analyses annually altogether, of which 20,000 are related to regenerated water; are in the process of accreditation according to the UNE EN ISO 17025 standard.
