Abstract

In case of demographic changes or emergencies pipeline bound infrastructure like gas or water is specifically challenged. Then, the advantages of decentralized infrastructure should be considered: Minimization of asset bound funds; flexibility; resilience; response capacity. A research project at the Federal Armed Forces University together with the Brazilian utility company COPASA, the process engineering company Grünbeck and the ICT company Phönix focused on: A procedure for successful decentralized water infrastructure implementation; a new operation scheme; related pilot tests. To describe the local situation the Open System of Boundaries is created comprising 13 interdisciplinary groups and 68 subgroups. To describe water supply systems the Open System of Attributes is created comprising 15 groups and 64 subgroups. An Attributes Profile which fits into the Boundaries Profile makes a resilient decentralized application more likely. For Minas Gerais, Brazil, i.e. for instable conditions the Boundaries Profile and the Attributes Profile of a decentralized SCADA equipped water treatment plant are compiled. Results of on-site tests are discussed. Recommendations for decentralized water supply under instable conditions are given. The application of standardized SCADA equipped treatment plants is suggested with remote supervision from one control centre.
