Analysis and assessment of water distribution network failures in Samara

Summary

The main task of the water distribution network maintenance and operation service is improving the quality and reliability of supplying water to the customers. The analysis of the water distribution network state in the urban district of Samara showed that the majority of the pipelines had been significantly depreciated. This is caused by fact that they were laid and put into operation during the period of large-scale housing construction (1960–1980-ies) without due account of the requirements to the durability of the materials applied and technical and organizational capacity of the operating companies. According to the statistics lately the rate of failures in the water distribution networks has been gradually but sustainably reducing. The assessment of the data on the operation and maintenance of the water distribution networks showed 22% reduction of the total number of failures in 2015 compared to 2013; accordingly water losses also decreased. Achieving these results was possible due to the timely repair and maintenance works in 2013–2015.
