The results application methods of calculations fire water supply for the needs of external and internal fire extinguishing on an example of a branch «Darnytsky wagon repair factory» PJS company «Ukrainian railway» to substantiate the decision on the need for the reconstruction of the water supply network. The analysis of fire hazard of objects that are part of the enterprise with the account of the features of technological process of production and daily consumption of water is given. The most dangerous building according to the level of fire danger, which is part of the enterprise, is determined, as well as an analysis of the situational location of the sources of external fire water supply that can be used in the event of fire suppression. The minimum required amount of water for the needs of the fire extinguishing of the object is calculated taking into account the type of danger of fire load. The type of water extinguishants, as well as the minimum quantitative characteristics of the forces and means that must be involved in the event of a fire to extinguish the object of protection, are determined. The actual state of the sources of fire water supply and fire water reserves with the account of the maximum daily water consumption for drinking water and production needs is analyzed, as a result of which the conclusion about the necessity of their reconstruction is made. A general conclusion is drawn based on the results of calculations by two alternative methods, which includes the economic substantiation of the methods. Characterized advantages and disadvantages of alternative methods of water consumption calculation.
