New approach for the selection of technologically most appropriate variant of the water supply system

Abstract

Experts and managers in the water supply sector are often challenged with a lot of different variants of obtained solutions for various types of water supply systems. Nowadays, in addition to meeting the technological and economic criteria, it is necessary to meet other criteria, such as environmental, social, political and other. Among other procedures, multi-criteria methods are used for the solution of such issues. This paper will present the use of the multi-criteria method Promethee for the case of technological criteria. The purpose of this is finding a technologically most appropriate variant of the observed water supply system, given that the resulting solution variants differ according to the size of certain parts. In addition, this paper explains the scientifically innovative and, in view of engineering, applicable methodology for dimensioning the sustainable urban water supply system driven by solar photovoltaic (PV) energy, which then becomes Energy Sustainable Urban Water Supply System (ESUWSS).
