The strategy of the sustainable development determines principles and terms of aqueous resources use by the population and the economy. Assumptions of coefficients of sustainable development in refer to water supply system (WSS) were shown. Graphic performance of sustainable development coefficients de-scribing drinking water demand was executed. In the thesis the influence of the water and sewage management on comfort connected with tourist living was pre-sented. To this purpose a three-parametric matrix of touristic's attractiveness and water-sewage management assessment was suggested. Analysis of touristic's attractiveness was introduced on basis of quantity of treated sewages (A), numbers of households having water supply system (B), classes of sanitary equipment of households (C). Each of parameters were attributed by three-level punctual scale (L = 1- low, M = 2 – middle, H = 3 – high). On the basis of statistical data exists a possibility of the parameters categorization A, B and C, and on this basis de-termination the indicator of WATGWS and the assessment of the touristic’s com-mune attractiveness. ...
