who is behind Context Carmelo Guerra Morales Mechanical Maintenance Operator “I specialize in mechanical maintenance and also have professional training on low-voltage electrical installations, allowing me to perform tasks like calibrating the SDP’s control devices and sensors. In addition, if an operations worker is on vacation or on paid leave, I can operate the plant. It’s very satisfying to make such complex equipment run like a well-oiled machine.” Bruno Ponce Santana Mechanical Maintenance Manager “Working with the Plant Manager, I plan and organize tasks to keep it running smooth-ly, like fixing mechanical and electrical faults and performing both preventive and correc-tive mechanical and electrical maintenance, as well as updating maintenance records for machines and equipment. I also support the Plant Operator on control and supervisory processes. Every day, we are moti-vated by the fact that our work contributes to the island’s well-being.” MIRIAM DE MARCOS bautista Técnico de Arboricultura “Gestiono el equipo de Arboricultura que revisa y diagnostica todos los árboles, las incidencias y tareas realizadas, además de elaborar los informes técnicos para que todos y cada uno de los ejemplares se mantengan sanos y se desarrollen correctamente. Es un gran desafío porque cada árbol es úni-co, tiene una historia y necesidades específicas que debemos tener en cuenta a la hora de tomar decisiones”. ARGELIS rodríguez LANTIGUA Podador de altura “Mantenemos sanos los árboles median-te podas y talas, quitamos ramas peligrosas y nidos de orugas procesionarias e instala-mos sustentaciones o trampas para plagas. Tenemos que ser expertos en técnicas de trepa y manejo de herramientas de apeo y corte como poleas, cuerdas, frenos y motosierras. Es muy bonito trabajar al aire libre, ver cómo cambian y crecen los árboles y todo el jardín”. CONTEXT The Arucas-Moya Seawater Desalination Plant (SDP), named after two towns it serves in Gran Canaria, was one of the first reverse osmosis desalination plants in the water divi-sion of ACCIONA, a company at the forefront of the technology. Since opening in 1995, it has undergone suc-cessive retrofits to equip it with state-of-the-art RO racks and 17 isobaric energy recovery devices that have allowed it to scale up its nominal capacity to 15,000 m3/day to meet the domestic and agricultural needs of some 45,000 residents of an island with almost no water resources. More than 860 self-consumption solar panels, 1,162 membrane units, eight filters (four sand and four cartridge filters), and a remineraliza-tion process ensure a high-quality supply which is more economically competitive due to lower consumption and has important sustainability parameters. The team of people responsible for managing, operating, and maintaining the plant is made up of ten professionals.
