Costa del Sol Desalination Expansion Steps Up Capacity for 2027 Water authorities move forward with major infrastructure works to modernise and double output across western coastal water treatment plants. Water managers across the Costa del Sol have accelerated infrastructure works designed to safeguard municipal drinking reserves ahead of next summer. Engineering teams have begun initial earthworks and component installation at key coastal supply points, marking a decisive shift from temporary drought management to permanent supply resilience. The primary focus centres on the western district, where municipal consortium Acosol is upgrading coastal pumping links and modernising intake facilities. The project aims to increase daily desalinated water contributions across coastal towns from Torremolinos through to Manilva, easing dependence on the La Concepción reservoir. Engineering Upgrades Along Western Coast Work crews are expanding membrane capacity and upgrading electrical substations to handle higher processing loads. The modernised pipelines will allow treated water to flow seamlessly eastward and westward along the coastal bypass corridor, preventing localised shortages during high-demand summer tourist peaks. Regional planners have earmarked over €30 million for secondary network links. These ensure residential urbanisations in elevated hillside areas receive uniform water pressure during scheduled maintenance windows, addressing longstanding infrastructure vulnerabilities highlighted over recent dry winters. Long-Term Security for Residents and Investors Reliable utilities remain a critical metric for overseas buyers evaluating long-term relocation. Infrastructure upgrades are transforming prospective property values in growing districts such as Estepona and Casares, where guaranteed municipal supply provides legal clarity for new developments handled by Marbella New Homes. Engineers report that the first phase of the upgraded intake system will undergo dry testing before Christmas, with full commercial commissioning scheduled for early spring. Town halls along the coast welcomed the milestone, noting that structural water security is essential to sustain the region's year-round population growth.
