    Abstract. At the current stage of housing and communal services reform, the requirements for the durability of pipelines in the city's engineering systems and their reliability are becoming increasingly stringent. As a result, the selection of the right material and type of pipe for specific conditions in urban water supply systems is crucial for ensuring the reliability of water pipelines in seismically active regions of Russia/ The article shows that today, high-strength cast iron pipes (HSCI) are the most promising for use in seismically active areas. It is noted that high-strength cast iron with spherical graphite (HSCI) has high strength properties similar to those of low-carbon steel (tensile strength, yield strength, and elongation) and increased corrosion resistance. The article provides information on calculating the seismic resistance of HSCI pipelines and verifying their safety for use in seismically active areas.
    Keywords: water supply, pipes, high-strength cast iron with spherical graphite, reliability, earthquake-prone areas
