The storage pond 8 is a water area with a levee 12, in which body the inlet water intake hole is made, and the opposite - a water receiver 9 of the water intake pipeline 22. According to the first embodiment of the method, at the bottom of the storage pond 8 the closed air-injecting devices 14, 15 are mounted to form a number of beams diverging from the device as horizontal perforated pipelines 16 in the direction of the base of the upper slope of the dam 12. The perforated pipelines 16 end with a dead end. The air-injecting devices 14, 15 are connected to the central supply pipeline 17, 18 connected to a source of compressed air. With the increase in the accumulation of sediment in the form of sludge in the zones of the storage pond 8 the air supply in portions into the air-injecting devices 14, 15 is resumed with brief connection of the compressor 19 on the command of the time relay 20 on the air duct in the intake pipeline of the closed air-injecting device. Breaking through the holes of the perforated pipeline 16, the compressed air loosens and roils the sludge, with simultaneous saturation of manure flow with it, and transports it to the discharge water intake pipeline 22. As the reduction in the sludge layer in the storage pond 8 the air supply into the air-injecting devices 14, 15 is stopped. According to the second embodiment of the method, in the storage pond a floating platform is placed, on which a compressor is located, connected to the pressure hose air duct.

In the presence of bending, the flow speed profile is more uniform in the pipeline, which reduces the tendency of flow separation from the inner curved wall and reduces the energy losses along the length of the pipeline, caused by the vortex turbulence. Pressure losses in the inlet portion at the presence of tubular portion, curved in three dimensions, as in the outlet portion of the pipeline, are reduced.
EFFECT: construction of water outlet as a whole provides its protection against the sediments, as well as in case of the absence of water inlet and simplification of the design at the increased discharge capacity, besides the length of the discharge pipeline is reduced respectively.
