Open-Source Application for Water Supply System Management: Implementation in a Water Transmission System in Southern Spain

Sustainable water use has become a critical issue for the future of planet in face highly probable climate change. The drinking supply sector made significant progress over last 20 years, although improvements management urban hydraulic infrastructures are still required. proposed system, Integrated Tool Water Supply Systems Management (ITWSM), built on three interconnected modules (QGIS database, Epanet model, and Google My Maps app), was developed open-source software. core ITWSM allows analyzing behavior systems under several operation/failure scenarios. It facilitates decision making supported by mobile application ITWSM-app. Information flows easily through different levels involved process, keeping updated georeferenced database after system changes. been implemented real public company applied to manage breakdown repairs transmission systems. methodology reduces average cost failure repair 13.6%, mainly due optimal planning resources involved.
