Sewer eco-collar for rigid sump
Abstract
An apparatus for use in catch basin openings and being located
on the inside peripheral edge of the storm sewer opening at or
immediately below the point where storm water enters the catch
basin opening. The apparatus includes at least one of trough
located along the inside peripheral edge of the storm sewer
opening. Each trough or trough section is located on the inside
peripheral edge of the catch basin opening and discharges to at
least one rigid sump. Each trough is positioned at or below the
elevation of the point where the storm water would normally
discharge down into the storm sewer and diverts the majority of
this storm water and any debris into the rigid sump from at least
one open end in each said trough. The rigid sump is cooperatively
engaged with at least one trough to form a modular unit. It is
envisioned that two modular rigid sump and trough combinations will
interconnect to form one apparatus for each catch basin. Both
trough and sump occupy a portion of the peripheral edge. An
absorbent material is incorporated into the apparatus to remove
oils and grease.

STATEMENT AS TO RIGHTS TO INVENTION MADE UNDER FEDERALLY SPONSORED
RESEARCH AND DEVELOPMENT
[0004] None
BACKGROUND OF THE INVENTION
[0005] 1) Field of the Invention
[0006] This application is in the field of storm water pollution
prevention and regulatory compliance with new storm water
requirements. The application is specifically designed for a catch
basin that has a bottom, walls rising from the bottom, a frame
mounted on the walls for supporting a catch basin cover, although
it could be employed for catch basin without a cover. These catch
basins come in many sizes and shapes; including circular,
rectangular and square catch basins. One trough is configured to
discharge water into one rigid sump through at least one open end
of the trough with both trough and rigid sump occupying the
peripheral edge of the catch basin where water enters is the key to
this invention. This would be one trough attached to a rigid sump
each occupying a portion of the catch basin perimeter where water
normally enters. The trough would be designed such that the
majority of the water discharges out of both ends of the trough in
this case. Each trough has at least one open end and the majority
of water discharge into a rigid sump is the key to this invention.
The top of the trough would be open and unoccupied, except for the
cover sitting above the trough and possibly some appurtenances
associated with the apparatus, which could include a supporting
member or a screen. The open and unobstructed trough would allow
storm water and debris to enter the trough from the peripheral edge
of the storm sewer system. Although a small portion of the top of
the trough could be obstructed by supported or miscellaneous
hardware, the majority of the top of the trough would be
unencumbered to allow unrestricted flow of water from the cover
into the trough. The design of the top of the trough would be such
that the majority of water and debris entering the catch basin from
above the trough would fall into the trough and flow out of at
least one open end to a rigid sump. An opening located at one end
of the trough would discharge most of the water entering the trough
through an open end into a rigid sump. The apparatus is designed
such that the rigid sump and trough are cooperatively engaged. A
rigid sump would extend from an opening in a trough to the other
end of the trough or to another trough. The rigid sump would be
cooperatively engaged with at least one trough to allow ease of
assembly. The trough apparatus is located on the inside peripheral
edge of the storm sewer catch basin opening. The location of the
rigid sump would be on the peripheral edge of the catch basin
opening as well such that the trough and rigid sump would each
occupy a portion of the peripheral edge of the catch basin where
water enters from above. In any event the trough(s) and rigid
sump(s) would not take up the entire catch basin opening and leave
a portion of the catch basin open and unoccupied. The entire
peripheral edge is occupied by the trough(s) and sump(s), while a
portion of the interior being open and unoccupied. The water
entering into the apparatus would fall into either the rigid sump
or the trough from above. The water and debris that entered the
trough would be directed to at least one open end in each trough
that discharges to a rigid sump. Said open end could comprise
opening in the bottom at the end of the trough as long as the
openings were over the sump. This is very plausible as the open end
may extend into the area occupied by the sump.
[0007] The invention removes particulate matter as the primary
treatment method through the use of a rigid sump or sumps with a
secondary stage of treatment of dissolved and liquid phase storm
water contaminants through the use of absorbent materials. The
rigid sump can accommodate an absorbent material within the lining
or through the placement of absorbent socks or pillows. These
absorbents are generally oil only absorbents meaning that they
repel water, but capture oils and greases. A rigid sump employed in
this devise would allow for greater strength and less chance of a
failure than a bag or non-rigid sump. In each case the rigid sump
would be permeable to water and have either one large opening or a
large number of small openings to filter out material, while
allowing water to pass. The top of the rigid sump or sumps would be
open at least in part.
[0008] Each trough would have a bottom at an elevation above the
bottom of a sump. The design of the trough would be such that the
majority or all of the water and debris entering the trough during
low flow would be directed to an open end of the trough and
discharge to a rigid sump. The openings in the trough that lead to
the sump would be sufficiently large to allow debris to pass. The
majority or the entirety of the trough, including walls and bottom,
would be constructed of a material that have a low permeability to
water, except for the places where openings exist. The preferred
method of support is to have one trough attached to one sump. These
trough and sump combination would be modular in that each sump and
trough would interconnect with another sump and trough to form a
complete unit occupying the entire peripheral edge.
[0009] 2) Description of the Prior Art
[0010] Numerous inventions in the field of storm water sewers and
pollution prevention have been patented over the last century that
can modify storm sewer catch basins to prevent or reduce pollution
from discharging out of the storm sewer or provide a support
mechanism for environmental products to be held within storm sewer
catch basins.

[0012] None of these aforementioned devices employed a trough in
combination with a rigid sump such that the majority of water
discharged out of an open end into a rigid sump.
[0013] McDermott--(U.S. Pat. No. 6,045,61) developed a device
specifically designed for catch basins with covers that uses the
existing lip of the catch basin to support the apparatus between
the lip and catch basin cover. A multiple trough system is used to
support an absorbent sock as the first stage of treatment followed
by a bag(s) hanging between successive troughs to catch particulate
matter and allow for separation of lighter fraction that rises up
to contact an absorbent sock held either in the trough or
incorporated in a bag(s). This patent application employs the same
principles, but there are two distinct differences including
employing a rigid sump(s) and requiring the majority of flow out of
one open end of a trough.
[0014] McDermott--(U.S. Pat. No. 6,623,633) developed a similar
device to this patent with the major differences that a rigid sump
is required and trough discharge out of at least one open end in
lieu of openings in the inner wall.
[0015] Therefore, this invention contains new matter not included
in either of these McDermott patents.
SUMMARY
[0016] It is the purpose of this apparatus to provide a mechanism
within a catch basin to hold absorbent material and a rigid sump in
such a way as to effectively remove storm water contaminants while
permitting storm sewers to function as intended without impeding
storm water flow into the storm sewer system. The apparatus utilize
very simple principles to effectively treat storm water, while
maintaining optimum flow rates in drainage systems. The structure
is located on the inside peripheral edge of the storm sewer opening
and designed to hold both absorbent material and a rigid sump(s)
which can remove dissolved and liquid phase contaminants.
[0017] Hence this apparatus has the purpose of removing a broad
spectrum of dilute liquid and dissolved contaminants from storm
water through the action of an absorbent material and collection of
solid contaminants in a rigid sump while maintaining optimum
drainage.
[0018] Applicant utilizes known inventions and techniques in the
field of storm water pollution prevention; including the use of
trough(s) and rigid sump cooperatively engaged to the peripheral
edge. However, the use of these is unique to all other inventions
due to the means of discharging water, including the location of
openings and the interaction of the trough system with the rigid
sump. The real innovation of this invention is the unique and
preferential means to divert water and debris to one or more rigid
sumps by means of open end(s) of the trough or a plurality of
troughs.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] The features, discussions and claims of this apparatus will
become apparent from the drawings and following description and
discussion. In each of these drawing the Number 1 denotes a trough,
Number 2 denotes a rigid sump, and Number 3 denotes an opening in
the trough.
[0020] FIGS. 1 & 2 represents the unit comprising two troughs
and two sumps oriented in a rectangular catch basin. Both FIGS. 1
& 2 show open ends on each trough.
[0021] FIGS. 3, is a top view of two troughs and two rigid sumps
with a configuration for a rectangular catch basin.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] This invention provides both support and flow diversion
devices to regulate flows into a rigid sump for treatment of storm
water into a catch basin with a cover. The support and flow
diversion device is one or more troughs that acts in cooperation
with the catch basin frame to support the trough or troughs by
gravity. The apparatus is positioned at or below the elevation of
the road surface where it intersects with the catch basin. The
trough extends several inches laterally along the peripheral edge
of the catch basin and contains openings to discharge water and
debris into a rigid sump. The trough(s) of this apparatus are flush
with the interior wall or frame of the catch basin. The treatment
of storm water occurs in rigid sump(s) where solids are collected
through simple sedimentation and filtration by small openings
within said rigid sump. The liquid and dissolved contaminants are
removed by the absorbent material located within the apparatus.
[0023] Key requirements are the majority of water entering the
trough discharge out of an open end or ends of the trough into a
rigid sump that occupies a portion of the peripheral edge of the
catch basin.
