Abstract
Reduction of environmental risks involved with the operation of public utilities in the Baikal natural territory presents a relevant research task. The safety operation of sewerage systems can be ensured by minimising the risk of emergencies related to the volley of sewage. In this study, we assess the rate of possible environmental damage from emergencies in sewerage systems as a result of their high wear and insufficient capacity. We provide a calculation of the prevented environmental damage during the reconstruction of the sewerage system in the territory of Irkutsk. In the conducted numerical investigations, technical indices of the operating sewers are accepted taking into account their capacity and natural-climatic factors of the Baikal natural territory. According to the results obtained, the total indicator of the prevented environmental and economic damage during the reconstruction of the sewerage system comprises 273.24337 thousand roubles (in prices for 2022). The reconstruction of sewers in the territory of Irkutsk will lead to a decrease in the volume of sewage discharges into the water bodies of the Baikal natural territory.
