Abstract
Open water bodies in areas with dense urban development experience an increased anthropogenic impact and, therefore, need restoration work, reconstruction and maintenance of the normative sanitary state of water. Many of them are closed, without flow. The article discusses technical approaches for maintaining the oxygen regime of urban water bodies, which is the most important indicator that determines the normalization of biological processes occurring in the aquatic environment. At present the only way to maintain the necessary hydrobiological characteristics of water bodies in urbanized areas is to create special hydraulic systems for artificial jet aeration of water bodies and circulation currents in such objects.
