Benefits of technology

[0006] This invention provides a method of treating watershed runoff and a watershed drainage device that is convenient and economic to install in an inlet of a vault having its outlet in

Problems solved by technology

Devices are generally available to satisfy the requirements for trash discharge control, but control of smaller, more complex suspended solids, hydrocarbon-based contaminants and dissolved metals require equipment that is more complex and expensive .
These inserts are efficient for trash removal but not necessarily for TSS or TOG, but they are less expensive, readily available, and standards for ac

Embodiment B

[0068] Another embodiment of this invention illustrated in FIGS. 5 and 6 is the watershed runoff drainage device 60. This device 60 includes the funnel sub-assembly 21, an additional permeable weir sub-assembly 61 described in detail below, a horizontal permeable weir filter element 62, and a vertical permeable weir filter element 63. Both filter elements 62 and 63 are removably inserted into elements of the permeable weir sub-assembly 61, plus deflector plates 23 selectively attached to the throat 240D and to the vault interior 16, ready for installation into a rectangular top-entry bottom-exit drain inlet vault 10. The deflector plates 23 serve two purposes, they slow and deflect rising liquid slowing the liquid velocity and increasing the fraction of settled solids and they serve as barriers to the vertical movement of the larvae and pupae mosquito stages, reducing their survival.

[0069] The permeable weir sub-assembly 61 comprises a welded SS angle frame 64 further ...

Embodiment D

[0075]FIG. 10 shows another embodiment of this invention, the device 90, which includes funnel sub-assembly 21 and deflector plates 23 of FIGS. 5 and 6. A “Rubberizer” carrier sub-assembly 100 has been added which floats on the liquid surface 58 inside the throat 24, just making contact with the ID surfaces of the funnel subassembly 21, and riding vertically on SS rods 54 which penetrate alignment holes 103, and which comprises four distinct layers of material positioned for assembly together as follows:

[0076] A “Rubberizer” carrier layer 102 made of mesh plastic material 110 with formed pockets 104 made to hold disposable plastic mesh pads 55, depicted in enlarged cutaway view in FIG. 10A, filled with “Rubberizer” particulate 44 and which also forms a separate pocket 105 to hold a plastic floatation tube 107, which can also be optionally added to the OD edges of the “Rubberizer” carrier layer 102, positioned between the SS rods 54 to provide buoyancy and stiffness alo...

Abstract

A watershed runoff drainage device is adapted to be used with a drain inlet vault for a storm drain. It includes a funnel member to be inserted into an inlet of the vault for directing substantially all water runoff entering the vault to flow there through prior to entering the vault. A floating hydrocarbon collector is positioned inside or outside the funnel member, and deflectors and other means within the vault inhibit the growth of mosquito larvae and the like within the vault and inhibit any mosquitoes within the vault from escaping the vault.
