In recent years, in the Russian cities there has been a decrease about 15-30% the total volume of water consumed and the specific indicator of water consumption per resident. However, this phenomenon is not taken into account in the SP 31.13330.2012, therefore the values of specific water consumption do not correspond to the modern level of sanitary equipment of the buildings and water consumption, which can not be the same for all cities and towns in Russia. Using the standard values of the design loads indicated in this code can lead to a significant increase in the cost of the project and operating costs. Their correction is necessary taking into account the assessment and forecast of the actual values of specific water consumption. This requires appropriate research and updating of specific water consumption standards for the design and reconstruction water supply and sewerage systems. The article describes the parameter justification method for the designed water supply systems under uncertainty of the prospective values of specific water consumption. The technique is based on the fuzzy sets theory and decision-making methodology under uncertainty of the initial information. This technique allows you to make decisions based on the minimum values of investment risks.
