Keywords: water distribution system, energy, pumps, efficiency.

This paper shows that the energy consumed by a water distribution system may be reduced by increasing the efficiency of the pumps. Improved efficiency of the pumping systems also contributes to the reduction of greenhouse gas emissions and reduction of environmental impact. The task is essential in water distribution systems with no water towers where the pressure in the system is regulated only by pumps. The water distribution system of Tallinn Water is an example of such systems. This paper concentrates on an algorithm for the prediction of the steady running of variable speed pumps in a group close to the best efficiency provided by the pump manufacturer. Special focus is on the pumps that run in parallel and have slightly different characteristics.
