The project is part of the specific funding program of the Federal Ministry of Education and Research (BMBF) with the topic: “Water technologies: reuse”. The aim is to develop new, highly flexible and needs-based management strategies for water reuse for urban and agricultural irrigation in a practical way. Concrete goals of the project are:

  • Elaboration of the prerequisites for an implementation under permit law for urban and agricultural irrigation practices

  • Establishing water quality requirements for different irrigation practices

  • Development of contemporary digital approaches for the automated recording, archiving and determination of irrigation needs, taking local and regional data into account in real time

  • Implementation of innovative multi-barrier treatment processes for efficient reduction of microbiological and chemical contaminants

  • Development of an automated, needs-based provision of further treated wastewater (= “process water”) including automated systems for quality assurance, taking into account real-time data

  • Development of innovative concepts for the implementation of utility water systems in existing buildings

  • Conception of adapted operator models and possibilities of technology transfer

  • Embedding the project from the beginning of the project in an interactive stakeholder process and

  • Establishment of an innovative public relations platform to present concepts of industrial water use to an interested public

LRZ’s main contribution is to use Internet of Things (IoT) technology to gather data in the field, transmit them to the LRZ Compute Cloud, where they are stored, backed up, and presented. The following picture shows a solar-powered sensor node that transmits the pumped water amount via LoRa to a central gateway node and from there via LTE and the internet to the LRZ Cloud.


An overview of this architecture is given in the following picture
