HYDRAULIC STRUCTURE FOR INTAKE OF SUBSURFACE SPRING WATER Russian patent published in 2010 - IPC E03B3/00 

FIELD: construction.

SUBSTANCE: hydraulic structure for intake of subsurface spring water comprises reservoir with charged bottom filter installed in water-bearing bed, and indicator of water level, pump with suction hose to pump subsurface water, reservoir for collection and discharge of spring water communicated with suction hose of pump, system of pipelines. Besides, it is additionally equipped with the second working reservoir, communicated with the first reservoir by means of split-level pipes, and a reserve reservoir communicated with the second working reservoir and installed below level of location of the latter. Besides, suction hose of pump is arranged in the second reservoir equipped with facilities providing for free flow of subsurface water into natural reservoir. At the same time the lowest split-level pipe is located below minimum water level in low water in the first reservoir. Both working and reserve reservoirs are arranged in serial order and are equipped with hydraulic insulation layer of required height arranged around each reservoir.

EFFECT: simplicity and reliability of design, production of cleaner water.
