The article is devoted to the problem of ensuring the safety of the environment. Technological measures are proposed to prevent environmental damage to environmental components by reducing filtration losses during water transportation through the channels of water management systems under normal operating conditions and under seismic effects. Most of the canals in the Rostov region are in poor condition, which leads to a rise in the level of groundwater, salinization and waterlogging of adjacent lands, flooding of territories, pollution of places of residence and a decrease in the standard of living of the population, destruction of the soil structure, water erosion and washout. The proposed linings for channels, made of concrete on inexpensive local aggregates, meet the requirements of safety, seismic resistance and resource saving. This is achieved by forced compaction of concrete mixtures, on aggregates with a high content of polluting particles, by pressing them (mixtures) and (and) rolling in the production of slabs and cladding, and an additional increase in the strength and performance properties of concrete, directed, including including, and to reduce the seismic response, is provided by a decrease in the initial water content of mixtures by adding a formiate-alcohol plasticizer to its composition. The measures recommended by the authors will significantly reduce the loss of water supplied to consumers both under normal and extreme operating conditions, and prevent flooding and pollution of adjacent areas. Improve the living conditions of the population, stop soil degradation. Used Books:
