CURRENT PROBLEMS OF SAFE AND RELIABLE WATER SUPPLY OF CITIES OF DONBAS
The author analyzes the problems of water supply in the cities of Donbas related to the impact of armed conflict. The analysis of the work of the municipal enterprise «Company «Water of Donbas» in the current conditions are completed. The article substantiates possible risk factors that reduce the safety and reliability of water supply systems. The distribution of incidents at the infrastructure facilities of water supply and sewerage related to the conflict in the cities of Donbas is analyzed. It was revealed that damage and destruction of facilities and infrastructure of the power supply system, occupies a significant part in the total number of causes of disruption of water supply and sewerage systems. The distribution of recorded incidents by type of damaged infrastructure of water supply and sewerage systems is analyzed. It was revealed that the greatest damage from hostilities was suffered by stations of water purification, which are one of the most important parts of the water supply system. The article reflects that the current state of the water supply and sewerage systems in the cities of Donbas is rather deplorable. Military action has an indirect effect on the physically worn-out infrastructure of the water supply system, increasing the operational load, which leads to an increase in the failures of this system. Steel pipelines that are used in these areas are now more susceptible to corrosion due to disruption of the functioning of electrochemical corrosion monitoring stations. The reliability and safety of the water supply system in the cities of Donbas is largely at risk due to the use of liquid chlorine to disinfect water, as many stations of water purification are located near the demarcation line and can be bombarded. There is also the problem of transportation and timely delivery of reagents required for water treatment processes. All the problems considered significantly affect the operation of water supply and sewerage systems and reduce their reliability and safety.
