Water supply systems for firefighting in small communities

Summary

The issues of arranging firefighting in small communities that usually lack firefighting water systems and the arrival of firefighting machinery sometime is delayed are discussed. The information on the availability of firefighting water systems in Russian communities and the number of fire accidents against population is presented. It is noted that special attention should be paid to establishing advanced water supply systems in small communities that can be also used for firefighting. A water supply scheme is proposed that provides for domestic water supply and external firefighting from fire hydrants eliminating the use of mobile pumping units. To accomplish this it would be reasonable to use regulating and reserve tanks to store a reserve water stock for firefighting; pumping units with variable speed drives; pipe fittings with electric operators; advanced automation equipment and water supply and distribution control systems. The options of operating modes of such water supply system in normal conditions and in case of fire are presented.
