The results of numerical modeling and field studies of the stability of technical water supply of large industrial enterprises are presented. Water consumption is one of the most important indicators of their operational reliability. This problem is especially acute for the enterprises located in zones of active technogenesis, where the dominant factor of pollution of water bodies is the presence of undeclared dispersed, so-called diffuse, sources of pollution. The reservoirs constructed in this territory to meet the purpose of technical water supply have a number of features that should be taken into account at the design stage. Typically, they are relatively small in size, and it is a priori assumed that the water masses produced in them are uniform in water area and depth. At the same time, in order to prevent possible accumulation of pollutants in the lower (near-bottom) horizons, they are generally flushed. However, the operating experience of such reservoirs in the development zone of the Verkhnekamskoe potash and magnesium salt deposit (VKMKMS) (Ural, Russia) showed that, due to intense diffuse pollution, significant vertical heterogeneity is formed in these reservoirs, which fundamentally changes their hydrodynamics. Based on a set of studies, including field observations and computational experiments, it is shown that the vertical heterogeneity of water masses plays a key role in ensuring the sustainability of technical water supply.
