Calculations of water consumption at the entrances to residential buildings for different standards of water consumption, the number of apartments and installed sanitary appliances are made on the basis of current and repealed regulations analysis. The results of the calculations are presented in the form of appropriate graphs. The comparative estimation and the analysis of the received settlement data are carried out. Three methods of calculating the volume of water consumption, which have been actively used in the practice of engineering calculations for the last 65 years, were considered during the preparation of the work. Namely: methods based on the use of the concept of equivalents that were introduced to describe the characteristics of each type of sanitary appliances; methods using the concept of the probability of action of sanitary appliances, as well as the current method, which is based on the ratio between the maximum and average hourly norms of water consumption. The results of the analysis allow to conclude that in the first considered building codes of previous years were significantly overestimated water consumption at the entrances to residential buildings. On the contrary, in the second it is somewhat underestimated. The most optimal discharges are given in the current building codes.
