A separator tank for separating and trapping contaminants in rainwater and runoff is disclosed. According to one embodiment of the present invention, the separator tank comprises a container having a bottom wall, side wall, and top wall defining an internal chamber; an insert located inside of the internal chamber, the insert comprising a weir defining an intake area between the weir and the side wall; and a round-edged orifice positioned within the intake area; an inlet conduit for introducing an influent liquid into the intake area; wherein the weir is positioned such that the weir induces the influent liquid to flow in a swirling motion within the intake area. According to another embodiment of the present invention an insert for a separator tank is disclosed. The insert includes a weir defining an intake area for receiving an influent liquid; and a round-edged orifice positioned within the intake area.

What is claimed is: 1. A separator tank, comprising: a container having a bottom wall, side wall, and top wall defining an internal chamber; an insert located inside of the internal chamber, the insert comprising: a weir defining an intake area between the weir and the side wall; and an orifice positioned within the intake area, said orifice having a vertically rounded edge connecting a larger outside diameter with a smaller inside diameter; an inlet conduit for introducing an influent liquid into the intake area; and wherein the weir is positioned such that the weir induces the influent liquid to flow in a swirling motion within the intake area. 2. The separator tank of claim 1, wherein the weir is curved to form a substantially circular intake area. 3. The separator tank of claim 1, wherein the weir is offset from the center line of the inlet conduit. 4. The separator tank of claim 1, wherein the insert further comprises a drop tube in fluid communication with the orifice and extending into the lower chamber. 5. The separator tank of claim 4, wherein the drop tube comprises at least one vertical vane to dissipate the swirling motion as the influent liquid flows through the drop tube. 6. The separator tank of claim 4, wherein the drop tube comprises a base formed by two wings for directing the influent liquid into the lower chamber. 7. An insert for a separator tank, the insert comprising: a weir defining an intake area for receiving an influent liquid; and an orifice positioned within the intake area, said orifice having a vertically rounded edge connecting a larger outside diameter with a smaller inside diameter. 8. The insert of claim 7, wherein the weir is curved to form a substantially circular intake area. 9. The insert of claim 7, wherein the insert further comprises a drop tube in fluid communication with the orifice and extending below the insert. 10. The insert of claim 9, wherein the drop tube comprises at least one vertical vane. 11. The separator tank of claim 9, wherein the drop tube comprises a base formed by two wings. 12. An insert for a separator tank, comprising: a weir defining an intake area for receiving an influent liquid; an orifice positioned within the intake area; and a drop tube in fluid communication with the orifice, the drop tube comprising: a base formed by two wings, wherein the two wines extend beyond the circumference of the drop tube. 13. The insert of claim 12, wherein the weir is curved to form a substantially circular intake area. 14. The insert of claim 12, wherein the drop tube further comprises at least one vertical vane. 15. The insert of claim 12, wherein the drop tube further comprises a back wall and front wall. 16. The insert of claim 12, wherein the two wings are angled downward. 17. An insert for a separator tank, comprising: a weir defining an intake area for receiving an influent liquid; an orifice positioned within the intake area; and a drop tube in fluid communication with the orifice, the drop tube comprising: at least two vertical vanes disposed in the drop tube, each vertical vane having a length, wherein the length of at least one of the vertical vanes differs from the length of at least one of the other vertical vanes. 18. The insert of claim 17, wherein the weir is curved to form a substantially circular intake area. 19. The insert of claim 17, wherein the drop tube comprises a base formed by two wings. 20. The insert of claim 19, wherein the drop tube further comprises a back wall and front wall. 21. An insert for a separator tank, comprising: a weir defining an intake area for receiving an influent liquid; an orifice positioned within the intake area; and a drop tube in fluid communication with the orifice, the drop tube comprising: a base formed by two wings; a back wall; and a front wall; said back wall and said front wall connecting said drop tube to said base; and wherein the arc length of said back wall is greater than the arc length of said front wall.
