In conditions of reduced freshwater reserves, the problem of its extraction of transportation and storage requires scientific justification of the relevant technical and technological solutions and the development of technical means. The article offers a mobile drinking water module. The design of the module provides for its placement in a thermally insulated container including a system of heating, power supply, distribution, filling and disinfection of water. For the development of the drinking water module, modern technical solutions are used to reduce the heat loss of the tank due to the use of a composite material and a cable of electric heater system. Reduction of microorganism propagation activity in water is provided by ultraviolet treatment and disinfection through ultraviolet gate. The design of the container is designed taking into account the possibility of its transportation in all modes of transport as a separate cargo unit. With the device of belts for loading and unloading. For loading into cars without the use of crane equipment, extendable outriggers are installed in the container, which can be used to install the container on water distribution sites. Mobility of the drinking module is ensured by the inclusion of a diesel generator unit in its composition. The tank of the module is made of stainless steel ensuring the safety of water without the formation of harmful impurities in it, and the coating of the tank with a composite material creates the effect of a thermos. The function of filling and distributing water from the tank is implemented using a distribution column with a vortex pump of a system of shut-off valves and hoses for supplying water. Experimental studies of mobile module operation have been performed. It was established that in order to maintain the water temperature in the tank at 10 ° C at an ambient temperature of minus 30 ° C, the heating system should not be switched on. The innovative design of the heat insulated layer reduces the thermal conductivity of similar water storage tanks made of traditional materials by 4 times. The proposed design of the mobile drinking module provides the possibility of creating clean water reserves for catering and household supplies.
