Summary
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.
