This paper discusses the methodology of derived water as a new frame for approaching the theme of water in urban ecosystems, with the attempt of determining the water-related carrying capacity of a given area from the regional budget of production-consumption system instead of the technological budget of water supply and water discharge. The evaluation of water equivalent of manufactured products at the level of final individual consumption constitutes the core of this study. According to the proposed classification of products, industrial water supply is correlated to industrial output of products and their distribution, which pattern is depicted by the hierarchical order of distribution and the delimination of consumption areas, for each prefecture of the Yodo River basin. Data of freight, of retail and wholesale trades, of industry, on the one hand, of water supply and water rights, on the other hand, are collected for this analysis. In the case of water supply allocation, the cartographical method has proved the possibility of synthesizing an aspect of regional water utilization systems. Results concerned with derived water are limited to a quantitative budget of total and local water equivalents of alimentary consumption, by prefectures, in accordance with the method of consumption areas.
