The concept of eliminating failures by the method
of re-laying sections of the water distribution and sewer networks

Summary

«The concept of eliminating failures by the method of re-laying separate sections of the water distribution and sewer networks» is presented that provides for changing the parameters of the network trouble sections subject to the replacement, or for correcting the criteria of making decisions about re-laying trouble sections. As a result, an increase or decrease in the length of the replaced networks for the reporting period is provided in accordance with the available capabilities. The proposed methodology in Vodokanal of Novokuznetsk for the control system arrangement allows the responsible personnel to make timely decisions on the network section re-laying; and visually and easily evaluate the results of the operations in current mode. Before the introduction of the control system, about 7% of the total number of trouble sections of the water distribution and sewer networks were subject to the replacement. Upon the introduction of the control system the number of replaced trouble sections increased to 20–22%.
