FIELD: power engineering.
SUBSTANCE: invention relates to hydraulic power engineering. The fountain is additionally equipped with an ejector pipe. One end of the ejector pipe is cut into a supply pipeline, and the other one - into a reservoir, which is made tight and is pre-vacuumized. Diameter of the pipeline supplying water into the reservoir is three times more than the diameter of the drainage pipeline from the reservoir. The level of water reservoir water is three meters higher than the level of the upper point of the reservoir. The diameter of the suction pipeline of the water pump is twice more than the diameter of the injection pipeline of the water pump and is equal to the diameter of the drainage pipeline from the fountain into the water reservoir.
EFFECT: technical result of the invention is reduced coefficient of friction of a water flow circulating in a fountain system and increased efficiency of a water pump.
