Energetical optimization of water distribution systems in large urban centers

In the present conditions of water distribution towards the users by pumping, in large urban centers, the reconsideration of the structure and functioning principles of the distribution systems, from the point of view of the energetical optimization, becomes a necessary and major problem, which can be solved by a new structural design. This paper presents and analyses in a detailed manner, giving numerical examples, certain optimization methods and solutions for the distribution systems, with a view to diminishing the pumping energetic consumption, using interior potential elements, ascertaining the energetical and economical efficiency
