Apparatus and method for increasing hydraulic capacity of a gravity sewer

a gravity sewer and hydraulic technology, applied in the direction of sewage draining, braking systems, braking components, etc., can solve the problems of sanitary sewer overflow, unintended water from non-municipal sources (i.e., stormwater) entering the sanitary sewer, and sanitary sewer overflow,

Benefits of technology

The invention provides a way to increase the capacity of a gravity sewer by adding a receiving structure at the end of a section of sewer that needs more capacity. When the receiving structure has low pressure, the sewer's capacity is increased. This allows for better control over the flow of liquid in the sewer system.

Problems solved by technology

Experience has shown that unintended water from non-municipal sources (i.e., stormwater) also enters the sanitary sewers.
During wet weather events these excessive flows create sanitary sewer overflows (“SSO”) at locations which were not intentionally designed to accommodate such overflows.
Such alternatives are often very expensive solutions to deal with short-duration problems created by only a few wet weather events annually.

Embodiment Construction

[0014]Certain terminology is used in the following description for convenience only and is not limiting. The words “left,”“top,”“up” and down,” and derivatives thereof, designate directions in the drawings to which reference is made. Unless specifically set forth herein, the terms “a,”“an” and “the” are not limited to one element, but instead should be read as meaning “at least one.” The terminology includes the words noted above, derivatives thereof and words of similar import.

[0015]Referring to the drawings, the first sewer pipe 12 of FIG. 1 has a maximum hydraulic capacity at full flow of a liquid, such as water, which is determined by its size and material-of-construction and its hydraulic gradient 14a. Likewise, the second sewer pipe 16 of FIG. 1 has a maximum hydraulic capacity at full flow of a liquid, such as water, which is determined by its size and material-of-construction and its hydraulic gradient 14b. It is preferred that the second sewer pipe 16 will have a full-flow ...

Abstract

A method for increasing hydraulic capacity of a gravity sewer system includes installing a receiving structure within or proximate to at least a portion of the gravity sewer system. The receiving structure has at least one fluid inlet opening, at least one liquid outlet opening, and at least one gas outlet opening. The method further includes evacuating at least some of any gas within the receiving structure through the at least one gas outlet opening to create a vacuum within the receiving structure, receiving a flow of at least liquid through the at least one fluid inlet opening of the receiving structure and into the receiving structure, and discharging at least some of the liquid from the receiving structure through the at least one liquid outlet opening of the receiving structure.
