SYSTEM FOR RECEIVING AND CLEANING STORM RUNOFF WATER Russian patent published in 2017 - IPC E03F1/00 E03F5/14 

FIELD: construction.

SUBSTANCE: system comprises a receiving sewage well (1) with a filtering module (4), having a blind bottom (2) designed for receiving runoff water, a first water discharge pipeline (13) from a receiving sewage well (1), a differential tubular riser, as well as a second pipeline (16) supplying water to the sewage header. The first and second pipelines are located at different levels of laying. The filtering module (4) is located in the receiving well (1) at a level providing the formation of the sludge area (5) of runoff water entering the receiving well (1) in the receiving well below the filtering module. The well is equipped with a means ensuring the water passage through the filtering module after filling the sludge area with it. The differential tubular riser has an open lower (9) end portion. The riser length is selected from the condition of ensuring the required value of the difference between the first (13) and the second (16) pipelines and from the condition of coming of the upper (8) end riser portion to the ground surface (19). The upper riser part is connected to the first pipeline (13) by the first fitting connecting means (10), the lower part (9) of the riser is connected to the second pipeline (16) by the second fitting connecting means (11). The riser has an open upper (8) end portion closed by a grid (18), ensuring the atmospheric air access to the riser.

EFFECT: reducing the number of structural units used in the system, applying a difference device simpler in design.
