This thesis contains specific example of a systematic approach to optimisation of drinking water distribution system. To carry out the reduction of electrical energy at water distribution, electric engine and pump knowledge described at the beginning of this thesis, is needed. Distribution system functioning and it is shortcomings are described later on. For optimisation and reconstruction of a system, a clear view of actual state of the system is indeed, beside the theoretical knowledge. With help of measurements we got the insight in functioning and recovery of the system. Web application Grundfos Product Center was our tool for choosing the most appropriate pump types. The app did a simulation of pump electrical power and evaluated reduction of energy based on suggested reconstruction. Based on calculated savings and basic investment, we made cash flow projections and suggested the optimal solution.
