Benefits of technology

[0008] The present invention is a sewage control system that prevents or reduces the pollution content of combined sewage or wastewater mixtures which often overfl

Problems solved by technology

However, when heavy stormwater flows occur, combined sewer flows often exceed the flow capacity of the interceptor; and the overflow is diverted into a receiving watercourse such as a natural stream or river.
However, in high rainfall climates over an annual period, CSOs may be a frequent occurrence resulting in re

Embodiment Construction

[0025] Referring to FIG. 1, in one embodiment, drains 15 as well as plumbing fixtures, for example, one or more commodes 16, tubs 17, sinks 18, etc., are connected to one or more soil stacks 19 in a building 20 and discharge wastewater through a building drain piping 22. The building 20 can be used for residential, commercial, or industrial purposes. The building drain piping 22 is connected to an intake or upstream end 23 of a building sewer service line 24, which is located below grade 25 and is often 6 inches (15 centimeters) or more in internal diameter for a single family dwelling. A discharge or downstream end 27 of the sewer service line 24 is connected to a sewer main 34. For purposes of this document, “downstream” refers to a location nearer to, or a direction extending toward, the sewer main 34, and “upstream” refers to a location nearer to, or a direction extending toward, the building 20.

Abstract

A wastewater source control system for use with a sewer service line conducting a flow of wastewater from a building to a sewer main. A flow control device is installed in the sewer service line with an upstream detention tank to detain building wastewater upstream from its point of discharge into a sewer main during certain heavy stormwater runoff periods.

Description

[0001] This application is a continuation-in-part of application Ser. No. 10 / 678,009, filed on Oct. 2, 2003, which is hereby expressly incorporated by reference herein.FIELD OF THE INVENTION [0002] This invention relates to sewage collection systems including both sanitary sewers and combined sewers. BACKGROUND OF THE INVENTION [0003] For purposes of clarification and understanding of this document, the following definitions are set forth. The term “wastewater” designates contaminated domestic wastewater such as “sanitary sewage” as well as water that carries away other waste matters from households, mercantile, commercial, and industrial establishments. “Stormwater” refers to rainfall runoff waters collected in sewers. “Extraneous inflows” refer to waters that enter a sewer collection system by infiltration from ground waters and by inflow from surface water sources especially during stormwater runoff periods. “Combined sewer systems” carry “combined sewage” that is a mixture of wa...
