The Spanish Army is planning to create a new Logistics Base in Córdoba, in a development known as “Project BLET” (85 agricultural hectares, developed into an industrial zone). The Sustainability Concept proposed here is framed within the context of the strategic management process as a Strategic Business Unit. Aligned with 2030 AGENDA, the above mentioned process focuses on efficient water management and is providing a drainage strategy based on the use of Sustainable Drainage Systems (SuDSs), as well as a water management plan that aims to consider rainfall as a key non-potable water resource. The purpose is to prepare a roadmap, based on the Project, and a methodology that guarantees the viability of the SuDS and its non-potable rainwater use. The final result could be a sustainable military logistics hub in Southern Europe, which would stand out for being a pioneer in the treatment of rainwater and have sustainability features that are intended to be certified and assessed by different institutions.
