SELF-REGULATING LAND RUNOFF WATER DISPOSAL SYSTEM Russian patent published in 2021 - IPC E03F1/00 

FIELD: water disposal systems.

SUBSTANCE: invention relates to the field of combined sewage and rain transport water disposal systems, it can be used to increase the efficiency of their work. The system includes a wastewater transport unit containing a water disposal network, an overflow pipeline and an emergency overflow device designed to be actuated when the water level is above the critical value at the control point. The water disposal network consists of a set of n sections containing a pipeline, input and output sewer wells. The emergency overflow device is made in the form of the kk-th section of the water disposal network with the diameter of the pipeline, kk = 1, 2, ..., n, - the calculated diameter of the pipeline. The system is additionally equipped with one additional sewer well and one additional pipeline. The overflow pipeline connects the input sewer well of the emergency overflow device to the additional sewer well, and the additional pipeline connects the additional sewer well to the output sewer well of the emergency overflow device. The overflow pipeline is connected to the input sewer well of the emergency overflow device at a mark that ensures the overflow of water through it when the water level is above the critical value at the control point.

EFFECT: invention provides increased environmental safety indicators, as well as possibility of using it in cases where there are no reservoirs nearby.
