This case study details the implementation of a water management solution by IOTLABS in Mallorca, utilizing LoRaWAN technology. The document outlines the company's background, established in Barcelona and now based in Mallorca, where it focuses on sustainable innovation through IoT-as-a-service. The project began with a pilot in the town of Esporles, which has expanded to cover the entire island. The solution allows for real-time monitoring of water levels and quality, enabling better management of water resources. The system has achieved up to 25 percent water savings and has fostered citizen engagement in conservation efforts. The case study highlights the collaboration between IOTLABS, local government, and other stakeholders to enhance infrastructure and promote resource conservation. Future plans include the addition of air quality monitoring and smart city solutions across Mallorca, demonstrating the scalability of the LoRaWAN network for broader environmental management.
