The invention relates to the field of urban water supply and sanitation, and is intended to determine the reliability and continuity of water supply and sanitation in accordance with the requirements of No. 416-FZ "On water supply and sanitation".

Known method of decomposition and reduction of the sewer network, designed to determine the relative volume of raw sewage discharged to the surface due to random failures of individual sections. The technique is reduced to the formal replacement of one fictitious equivalent channel, the reliability parameters of which are calculated from the known failure rates of rebounds and plots (see Ermolin J. A., Alekseev M. I. Method of decomposition and reduction of sewer networks Water supply and San. technique. 2012. No. 11).

Method of decomposition and reduction has the following disadvantages:

1. Limited scope because it:

- allows you to calculate only one indicator - the ratio of the flow rate allowed by the network. It does not allow to determine the probabilistic reliability indices, such as continuity, which in accordance with the Federal law of 07.12.2011 № 416-FZ "On water supply and sanitation" are targets of organizations;

- not p�adequate to assess the effectiveness of the device jumpers between the separate sites because developed to calculate network security only "tree" configuration. However, this method of improving the reliability of well-known and widely used in practice, for example, ring a tunnel header along the river Fontanka in St. Petersburg;

- does not allow to calculate the security flow rate allowed by the network in the partially-operational state, i.e., when the failure of individual sections of the network.

2. High accuracy, because in it, for the purpose of simplification introduced a number of assumptions, significantly lowered the accuracy of the calculations.

The closest analogue to the claimed invention is a Device for reliability analysis of pipelines municipal Sewerage network," taken as a prototype, is equipped with a primary unit of information processing, the block of collecting and processing information on the structural damage and the block of collecting and processing information about the functional pipeline, the inputs connected to the outputs of block filtering options for selecting potential sites for rehabilitation, and the outputs to the inputs of the block of ranking potential sites for the rehabilitation, the filter blocks the reliability parameters, the filtering parameters to select potential sites for the rehabilitation, ranking potential sites for the rehabilitation of sequentially interconnected, and the blocks ranking criterion� accidents, filtering and analysis of primary information and queries on the operation, selection of potential sites for the rehabilitation of inputs connected in parallel to the outputs of the primary unit of information processing, and outputs to the inputs of the filtration unit of the reliability parameters for which input is also connected to the outputs of the unit of collection and accumulation of information about the accidents of pipelines and gathering information for the inventory. The block of collecting and processing information about structural damage to pipelines made in the form of parallel-connected to the input of the block of cells of collecting and processing information on cracks, failure modes, corrosion deposits, and abrasive wear, the outputs of which are connected to the output of the block. Also block functional changes of pipelines made in the form connected in parallel to the input of the block of cells of collecting and processing information on the availability of offset pipes, on the subsidence of the tray, about violations of the original shape of the pipe, the presence of sediment and boopathi, outputs connected to the output of the unit (see RF patent №2237784 (priority from 25.03.2003) "Device for reliability analysis of pipelines municipal Sewerage network").

Device for analysis of pipeline integrity management urban drainage network has a limited field of application, because it's designed only for zboray analysis of the reliability of pipelines and cannot be applied to assess the reliability of the entire network, because:

- not possible to determine the probabilistic reliability of the entire network in the form of the probability of the network at time t in a healthy state in the absence of failures it plots the probability of finding the network in the partially-operational state (not being a network failure) when the j-th site at time t in a state of refusal, etc.;

- does not identify a technological indicator of the reliability of the entire network in the form of a volume of water distribution network for the billing period of operation t if it is in working condition, etc.;

- does not identify a technological indicator of the reliability of the entire network wastewater volume in the form of emergency discharge of untreated sewage due to accidents and obstructions of the j-th plot, etc.;

- not possible to determine the technological parameters the reliability of the Sewerage network in the form of emergency discharge of untreated sewage due to accidents and obstructions of the j-th phase, the volume of the water distribution network for the billing operation period t when it is in partially working condition in the conditions when the network configuration allows you to change the flow distribution due to accidents and obstructions of the j-th plot.

For this reason, the use of the device to determine one of the targets of the activities of organizations engaged in videoteen�e (the reliability and continuity of drainage, in accordance with the requirement of article 39 No. 416-FZ "On water supply and sanitation") is not possible, because it can only determine a single reliability of pipes and sections, not the whole system.

In this case, the network configuration is different from the "tree" and in the accident and the clogging of the j-th plot of the flow rate of the emergency discharge of untreated wastewater will not be equal to the flow rate of this site. For its determination it is necessary to simulate the accident in this area. In this case, the block 4 determine the technological reliability of the Sewerage network is further provided with a cell network modeling 23.

The system operates as follows.

In block 1 the collection of primary information (Fig.1) through an external connection (not shown) enter the following information about drainage �the Yeti:

- the number of sites n is in cell 5;

In unit 2 calculation of indicators of reliability of the network elements are calculated:

- reliability of pipes in the cell 12, which is arranged to determine the failure rate λjand obstructions λjdrainage systems the dependencies listed in the claims depending on material and diameter Dj. For example, when the diameter asbestos cement pipes j-th plot of Dj=0.2 m failure rate and strainers are respectively equal toλotKazj=0,048Dj0.8=0,0480,20,8=0.174 were revealed(1/godKm))andλ aCopj=0,16Dj1.2=0,160,21,2=1.104(1/godKm))see the evaluation results for section 12-13 of Fig.2. In addition to the failure rates of the cell 12 is determined by the length of the pipe repair by the formula:

tj=(8760/(8760/(485·0,001·Dj-504·(0,001·Dj)2-27)),

where tj- the duration of the repair of pipes j-th plot, h; Dj- the diameter of the pipes j-th section, mm. for Example, when Dj=200 mm tj=(8760/(8760/(485·0,001·200-504·(0,001·200)2-27))=49,84 including Information about the materials and the diameters of the pipes comes from the unit 1 primary information processing (cells 7 and 11).

For example, when the diameter of the section of asbestos cement pipes Dj=200 mm, the intensity of repair of a site will be equal to µj=8760/(485·0,001·Dj-504·(0,001-Dj)2-27)==8760/(485·0,001·200-504·(0,001·200)2-27)=175,76, where µj- the intensity of repair of the j-th network area, 1/year; Dj- the diameter of the pipes j-th section, mm.
