Sanitary, storm and catch basin trap with filter insert
View Patent ↗A temporary trap having baskets and optionally filters in the baskets used in conjunction with inlets for sewer systems to keep debris, oils or chemicals from being washed into the sewer during construction of roads and sewers. The trap is a box, typically rectangular, square or round, with baskets having a plurality of holes therein for allowing water to pass therethrough while trapping debris therein. The trap is inserted into a inlet by lifting the grate off the inlet frame, inserting the trap and then replacing the grating. After a rain the baskets and filters may be cleaned out and reused or replaced. When the construction project is finished the grate is lifted off the inlet frame and the trap removed. The trap has an overflow opening in case the trap becomes clogged.

2. A catch basin inlet trap as in claim 1 wherein,
the matter catching member has handles attached to the top thereof.
3. A catch basin inlet trap as in claim 1 wherein,
the trap insert housing has a rectangular peripheral wall.
4. A catch basin inlet trap as in claim 3 wherein,
a curb box blocker extends upward from the top of the flange on a back peripheral wall to block water flow from entering the catch basin by entering a inlet box thereby bypassing the catch basin inlet trap.
5. A catch basin inlet trap as in claim 3 wherein,
three adjacent sets of four flanges attached to the peripheral walls to engage the flanges and support three matter catching members.
6. A catch basin inlet trap as in claim 5 wherein,
one of the adjacent sets of flanges is recessed downward relative to the other two sets of flanges.
7. A catch basin inlet trap as in claim 3 having,
a base at the bottom of the peripheral walls, the base having at least one aperture with flanges around the at least one aperture for engaging the flanges on the matter catching member.
8. A catch basin inlet trap as in claim 3 wherein,
the trap insert housing has a curb box blocker extending upward from the one wall to block water from entering a curb box.
9. A catch basin inlet trap as in claim 1 wherein,
the matter catching member has at least one side wall with apertures therein and a bottom having apertures therein.
10. A catch basin inlet trap as in claim 9 wherein,
a filter inserted inside of the matter catching member.
11. A catch basin inlet trap as in claim 1 wherein,
a filter inserted inside of the matter catching member.
12. A catch basin inlet trap as in claim 11 wherein,
the filter has a bag shape with an opening at the top and is inserted into a basket shaped matter catching member.
13. A catch basin inlet trap as in claim 12 wherein,
the filter has at least one tie for securing the filter to the matter catching member.
14. A catch basin inlet trap as in claim 12 wherein,
a top portion of the bag shaped filter has a folded over portion with a draw string therein to draw the filter opening to a smaller perimeter.
15. A catch basin inlet trap as in claim 11 having,
a filter material for filtering grades of sand.
16. A catch basin inlet trap as in claim 11 having,
a filter material for absorbing oil.
17. A catch basin inlet trap as in claim 1 wherein,
a bar extends over the top of the aperture in the peripheral wall from one side of the trap insert housing to the other side.
18. A catch basin inlet trap as in claim 1 wherein,
a support frame having a front flange for engaging a front wall peripheral wall and a rear flange for engaging rear wall peripheral wall with rods connecting the front and rear flanges for providing support for the trap insert housing.
19. A catch basin inlet trap as in claim 1 wherein,
the trap insert housing has a cylindrical peripheral wall.
20. A catch basin inlet trap as in claim 19 having,
a base at the bottom of the peripheral walls, the base having at least one aperture with flanges around the at least one aperture for engaging the flanges on the matter catching member.
21. A catch basin inlet trap as in claim 1 having,
the at least one aperture in the peripheral wall between the top flange and the internal flange has a top and a bottom, with a rod extending from the top to the bottom.
