Over 100 of Poland's towns were investigated for the use of water and relevant variations in the past decade. The total amount of water which is used in those towns accounts for approximately 60% of the total water amount used for industrial and municipal purposes all over the country. Relevant data sets were processed so as to show the unit use in a respective town, as well as the rate of decrement in water use in the past decade. Analysis of variations in the use of water from municipal supply in the time span of 1987-1998 revealed a decrement in unit use, which varied from one town to another, but in the majority of them was greater than 30%. These data evidence that the continuing increase in water consumption observed in the post-war period has been inhibited, and that in the past decade there has been a noticeable decrease in the use of water. This finding substantiates the need of verifying the previously predicted quantities of water use in Poland's towns. Because of the lack of adequate data for assessing the duration of the new trends in municipal water consumption, it is necessary to adopt the principle of continuous analysis of annual water use in Poland's towns and continuous verification of the available forecasts. Having such data is a prerequisite for the development and modernization of municipal water supply systems, as well as for establishing adequate service charges.
