The invention relates to sewage and can be used for water removal from sports and recreation, towns, both permanent and temporary accommodation, and transportation of industrial waste water and rainwater.As can be seen from the diagram RA is Varah, you connect to the network. The system provides for the use of sanitary-technical devices or valves before them 
Disadvantages of the considered system using special sanitary appliances and valves that require replacement in 3-5 years the rubber seals, and significant power consumption during continuous operation of the vacuum pumps.Closest to the invention to the technical essence and the achieved result is gravity-vacuum sewer system containing gravity sewers, foster and prefabricated tanks, suction and discharge pipes, siphons, nodes removal of the gas and pumps 
The disadvantages of this system is the limited length of the network, the possibility of siltation siphons, as it is difficult to provide the necessary velocity to flush the system without drastic decrease of the liquid level in the collecting tank.The purpose of the invention, the reduction of energy costs, reducing capital and operating costs, increase the reliability of the system
This objective is achieved in that in a gravity-vacuum sewer system containing gravity sewers, foster and prefabricated tanks, vsasyvauschie the selected branch pipe, forming the body and end sections of suction tubes arranged in the housing. The initial sections of the suction pipe and end sections of the drainage pipes are installed in adjacent tanks in the immediate vicinity of their heads. The height difference of the depth precast tank and receiving tank is equal to the sum of hydraulic losses in areas of the system between them. The open ends of the suction pipes in the siphons are located above the level of the bottom of the gravity sewers in place of the tie-in to receiving tanks. Discharge pipe siphons, the latter in the direction of travel of the fluid, is connected to the suction pump nozzles made of the centrifugal.In Fig. 1 shows a gravity-vacuum sewer system plan; Fig. 2 is a longitudinal section.Gravity-vacuum sewer system consists of gravity of the collector 1, a receiving tank 2, the suction pipe 3 with the valve 4, is placed in the well 5, the intermediate station 6, where the siphons 7 knots gas outlet 8, discharge pipes 9 with valves 10, prefabricated tanks 11, suction pipe 12 with the valve 13, the pump station 14, which is placed siphons 15 knots gas outlet 8, discharge pipes 16 with sadienardini 23, centrifugal pump 24 from the discharge pipe 25, which has a valve 26, in the upper part concentric siphons 7, 15, 19 embedded pipes 27 with valve 28.Gravity-vacuum sewage system works as follows.Before putting the system into operation to produce charging, i.e. filling the system with water. With closed valves 4, 10, 13, 17, 21, 23 and open the valve 28, through the nozzles 27 siphons 7, 15, 19 the system is filled with water. Water filling system, expels the air out through the nodes of the gas outlet 8. After charging, close the valves 28 and open the valve 4, 10, 13, 17, 21, 23.Waste water through a gravity sewer 1 enters the receiving tank 2, increasing the rate of fluid, increasing the height difference with the liquid level in the collecting tank 11 intermediate stations 6. When the difference of liquid levels in tanks greater than the sum of hydraulic losses at the entrance point of the liquid in the suction pipe 3 to its exit from the bypass pipe 9, under the influence of vacuum in the siphon 7, the fluid begins to flow from the reservoir 2 into the tank 11. The magnitude of the vacuum in the siphon, and therefore, the pressure difference in the network is determined by the excess of the open end of the suction TRU is porterhouse liquid on the parts of the systems is determined by the height difference of the levels in the tanks.The flow of the liquid in the collection tank 11 intermediate stations 6 enhances the level of liquid therein, increasing the height difference with the liquid level in the collecting tank 18 pumping stations 14. When the difference of liquid levels in the tanks 11 and 18 is greater than the sum of the hydraulic losses in the section of the system between the tank under the influence of vacuum in the siphon 15, the liquid will begin to flow into a collecting tank 18 pumping stations 14, increasing the rate of fluid. In this case, due to the fact that the stamp to a receiving tank 2 above the bottom of the collecting tank 11 pumping station 6, and mark the bottom of the collecting tank 18 pumping stations below the bottom of the tank 11. The difference of these markers is equal to the sum of hydraulic losses in areas of the system between these tanks. A slight increase in the liquid level in the receiving tank 2 will provide transportation of liquid in the collecting tank 11 and 8. When the liquid level critical level in the collecting tank 18 pumping stations 14 automatically switches on the pump 24. From siphon 19 through the outlet pipe 22 of the pump, draining the fluid creates a vacuum in it.Under the influence of vacuum in the siphon 19 through sasivadana fluid reservoir 18 increases the height difference with the liquid level in the collecting tank 11 intermediate stations 6, including a siphon 15, providing transportation of liquid from the reservoir 11 into the reservoir 18. In turn, the decrease of the liquid level in the tank 11 causes the transport of fluid from the receiving tank 2 under the influence of vacuum in concentric siphon 7 in precast reserve tank 11. At lower liquid level in the collecting tank 18 pump station 14 to a critical point, the pump 24 is switched off automatically. The sharp decrease of the liquid levels in the tanks by pumping liquid from the collecting tank 18 by the pump 24 causes a relatively large transportation speed in the pipes, ensuring their washing, which prevents them from silting.To ensure pumping of fluid height difference to the axis of the pump 24 and the minimum liquid level in the collecting tank 18 in the amount of hydraulic head losses from the entrance of the liquid in the suction pipe 20 to the entrance of fluid into the working cavity of the pump 24 should amount to less than the allowable vacuum-metric height suction pump.Under the influence of vacuum in the siphon and flow through them to be released gas to accumulate in the upper part of the siphons. Therefore, to ensure stability rasti siphons are automatically included vibrating pumps automatically turn off.Gravity-vacuum Sewerage system for a short length sections can operate without an intermediate station 6. In this case, the suction pipe 3 under the influence of vacuum through the siphon 15 will transport the fluid from the receiving tank 2 into a collecting tank 18 pumping stations 14.The system is gravity-vacuum sewage system allows you to:
to create a negative pressure in the network, providing transportation of wastewater without the use of vacuum pumps due to the fact that siphons made in the form of concentrically arranged primary areas branch pipe forming body, and the end sections of suction tubes arranged in the housing, with the initial sections of the suction pipe and end sections of the drainage pipes are installed in adjacent tanks in the immediate vicinity of their heads, the height difference of the depth precast tank and receiving tank is equal to the sum of hydraulic losses in areas of the system between them, but the open ends of the suction pipes in the siphons are located above the level of the bottom of the gravity sewers where they tie into the receiving tank, which reduces energy consumption and simplifies the operating conditions of the system;
to operate the pump, the suction pipe precast tank pumping station attached through the siphon to the suction pipe of a centrifugal pump, thereby reducing the depth of the machine shaft of the pumping station;
to use traditional sanitary appliances and install on releases suction valves with boxes control due to the fact that sewage releases from buildings embedded in gravity sewers, which ensures the reliability of the system and facilitate its operation;
to increase the length of the vacuum network due to gravity sewers and intermediate stations, which expands the possibility of using vacuum Sewerage systems;
the use of open tanks vacuum system through the use of siphons, so there is no need in sealed metal prefabricated tanks of relatively large volume.
