The use of pipes made of various materials for the construction of sewer networks

Summary

The results of the analysis of data on sewer networks in settlements of Russia as of 2014–2019 are presented. All settlements are divided into six groups depending on the number of inhabitants. For each group, the distribution of sewer networks is established depending on the material of the pipes. Сeramic and cast iron pipes have been most widely used over the past 100 years. Schedules for commissioning sewer networks made of various materials over the years have been developed. Over the past 20 years plastic pipes have gained widespread use accounting for about 50% of newly constructed sewer networks. Information was collected on the commissioning dates of individual sections of sewer networks. The largest number of the operating sewer networks was built between 1970 and 1979. In general, the standard service life for 55% of networks was exceeded in all settlements. In the coming years, a significant increase is expected in the share of plastic pipes in the total length of sewer networks.
