Different ways to reduce the threats of emergency situations on ownerless hydraulic structures
This publication discusses the problems of ownerless hydraulic structures, their aging, the progressive deterioration of their condition, the lack of control over their condition, the increase their number every year, the increased potential danger from them, the absence of an owner who should maintain the structures in a safe condition. It is carried out a quantitative and qualitative analysis of the state of ownerless hydraulic structures, the dynamics of these processes over time. The results of field surveys conducted in 2019-2020 are summarized, it is assessed the technical condition of waterworks and structures in Moscow, as well as the possibility of their further operation and potential threats. Based on this research, it has been developed a preliminary scheme for identifying ownerless hydraulic structures for small waterworks and making decisions on the further operation or liquidation of ownerless hydraulic structures.
