Abstract

The invention is a filter mounted below a perforated grate cover (22) of a storm water inlet basin (20) suspended from a means of support, comprising inserted rigid bars (10) which rest upon at inlet cover support (28), which hold in position a catch basin insert comprising bar sleeves (6), storm water bypasses located in corners of the catch basin formed by vertical slit openings (12), and a bridge flap (2) which channels water above and over the bypass into the inside of a filter basket assembly (24) and the bag assembly is premanufactured in a continuous roll (14) and can be adapted to fit various catch basin sizes in the field on site.

Claims

1. I claim an insert

a) located within a storm water inlet basin

b) with a perforated cover

c) that rests on a support within the top opening of said inlet basin

d) with a filter bag assembly located beneath the cover

e) with a support means to hold said catch basin insert in position within the inlet basin,

f) with a filter bypass comprising an opening formed in said filter bag assembly whereby said opening provides a channel for excess water to escape out of the basket assembly through said opening.

g) the improvement characterized in that the bypass openings are essentially located in the corners of the catch basin whereby the water will flow out of the bag assembly at the locations within the inlet basin where there is the most available space between said filter basket assembly and the inlet basin.

2. The bypass opening of claim 1 further comprises a narrow vertical slit that releases water through the opening but prevents an escape of a pillow from the interior of the bag assembly.

3. The basin insert of claim 1 further includes a continuous role comprising a filter fabric from which said filter fabric separates and which can form into the basket assembly on site at the location of the inlet basin, and a tie that closes the bottom of the basket assembly holding it together in a bottom tie gathering.

4. The filter basket of claim 1 further includes permeable fabric, whereby pollutants are filtered from storm water whereby the bag assembly is easily formed and cut.

5. I claim a basin insert,

h) located within a storm water inlet basin,

i) with a perforated cover,

j) with a filter basket assembly located beneath the cover,

k) that hangs on a rigid support to hold the assembly in position within the inlet basin,

l) the invention wherein a majority of the basin insert is manufactured in a continuous roll and separates from said continuous role and said continuous roll comprises filter fabric for multiple inserts that can be formed, at the location of said inlet basin, into a basin insert comprising a filter basket with semi vertical sides and a bottom closed with a tie.

6. Said continuous roll of claim 5 further comprises a sleeve formed into the length of the rolled fabric where by the basin insert easily attaches to a rigid elongated support structure.

7. The tie of claim 5 further includes a plastic zip lock that securely holds the assembly bottom tie gathering.

8. Said continuous roll of claim 5 further comprises a bridge flap that is positioned in the insert to essentially conduct water from essentially all of the upper periphery of the inlet basin to the central inside of the basket assembly.

9. The basket assembly of claim 5 further comprises one or more bypass openings that form a vertical narrow slit in said filter fabric that prevents large pieces of material including an absorbent pillow are from escaping through said bypass opening.

10. Said filter bypasses of claim 9 further comprise locations essentially positioned only in corners of a rectangle catch basin where the maximum room for water flow, between the filter basket and the basin, is located.

11. I claim in a basin insert

a) located within a storm water inlet basin,

b) with a perforated cover,

c) that rests on a support within the top opening of said inlet basin,

d) with a filter bag assembly located beneath the cover,

e) the invention comprising the combination of a support means that positions the insert within the basin using elongated semi rigid material located on three or more sides of the basin and one or more water by passes that are located essentially in the corners of said inlet basin.

12. The bag assembly of claim 11 further comprises a bypass means that forms a vertical slit in an upper portion of the filter basket whereby large items do not easily pass through the bypass.
