ABSTRACT
The subject of the article is the methodology for calculating the degree of water supply diversification in water supply systems. The presented methodology proposed three parameters affecting the degree of water supply diversification: the maximum production capacity of water intakes, the volume of water tanks, flowability of pressure pipelines of the second degree pumping station. Dimensionless simpson ratio were calculated and the degree of diversification of the given collective water supply system, as well as compare even very different water supply systems was determined. The paper presents the calculation of simpson diversification indexes for selected collective water supply systems.
