Acosol Revives €50 Million Overhaul to Double Capacity at El Verde Treatment Plant Water operator Acosol initiates design tenders to double output at Marbella's El Verde facility, securing long-term supplies for western Costa del Sol municipalities. Public water operator Acosol has officially put the engineering and design contract out to tender for a €50 million expansion of the El Verde drinking water treatment plant in Marbella. The strategic facility, positioned adjacent to the La Concepción reservoir, currently provides potable water across eleven western municipalities from Torremolinos through to Manilva. Under the newly tendered framework, regional authorities intend to double the plant's operational processing threshold from roughly 2,300 litres per second to 4,600 litres per second. Reinforcing Regional Resilience The project marks a major structural response to the erratic rainfall patterns and sustained demographic growth experienced across southern Andalusia. For years, the western coastal belt has operated close to its treatment margins during peak tourist influxes, depending heavily on transfers and desalination backups. Engineers drafted initial blueprints for El Verde more than a decade ago, but budgetary constraints halted formal execution. The revival of this infrastructure package demonstrates a renewed institutional drive to safeguard domestic consumption against future severe climate oscillations. Alongside expanded processing units, the tender outlines modernised carbon filtering and automated flocculation systems capable of handling degraded raw water from lower reservoir reserves. Regional officials confirm that the drafting phase will require roughly twelve months, with physical construction expected to commence toward late 2027 under a multi-stage execution schedule aimed at keeping current water lines operational without disruption. Impact on Residents and Municipal Supply For local residents, community urbanisations, and businesses, the plant upgrade represents essential stability. Water restrictions introduced during recent dry seasons highlighted vulnerabilities in municipal piped networks, leading to pressure cuts and landscaping bans. Doubling El Verde's treatment capability directly mitigates these strains, allowing town halls to maintain reliable flow even when surface reservoirs run down. The investment complements broader water-security measures across the Costa del Sol, including the modernisation of the coastal brine network and distribution pipes. Regional planners point out that securing uninterrupted, clean water remains the foundational prerequisite for sustaining the coast's residential vitality, hospitality sector, and international investment pipeline.
