The blocks of the primary processing of information 1 and the ranking of potential objects of rehabilitation 10 are connected to print1, device 2.

complex information about the status of the drainage networks is introduced into the unit for collecting historical information 1 (Fig. 1) via external communication channels (not shown in the drawing); This information may come in writing - questionnaires, protocols, inquiries, complaints, in the form of faxes and telephone messages.

This information is filtered in parallel by the installed units for collecting and accumulating information about the accident rate of pipelines 3, collecting information on inventory 4, ranking according to accident criteria 5, analyzing and filtering primary information and operation requests 6, selecting potential rehabilitation and emergency facilities and 7, forming As a result, five1 streams of information about the status of drainage networks.

In the block (}) of filtering the reliability parameters 8, the information available on these five channels is compared and the selection (narrowing of the list of network sections) of the most unreliable sections of the drainage network is made. Information about the selected sections is sent to the filtering unit and the parameters for selecting potential objects of rehabilitation 9, in which a repeated analysis is carried out for the degree of inferiority by such indicators as the depth of the pipes, the year of laying, the material and diameter of the pipes, the wall thickness, the presence of groundwater, the nature soils, traffic intensity, etc.
