Abstract

Weir systems, methods, and apparatuses for containing and filtering runoff may be provided. In one implementation, a modular weir may be used to isolate suspended solids from a flow of water in a stormwater management crate array. The modular weir may include a plurality of weirs configured to isolate the flow of water from the stormwater management crate, a plurality of column grooves along the one or more weirs configured to extend around a plurality of columns in the stormwater management crate, an inlet located at a first end of the plurality of weirs configured to receive the flow of water within the stormwater management crate, and a cap located at a second end of the plurality of weirs configured to contain the flow of water within the modular weir.

Claims (49)

1. A modular weir configured to isolate suspended solids from a flow of water in a stormwater management crate, the modular weir comprising:

a plurality of weirs connected together, the plurality of weirs being configured to isolate the flow of water from the stormwater management crate;

a plurality of column grooves along the plurality of weirs configured to extend around a plurality of columns in the stormwater management crate;

an inlet located at a first end of the plurality of weirs configured to receive the flow of water within the stormwater management crate; and

a cap located at a second end of the plurality of weirs configured to contain the flow of water within the modular weir;

wherein each of the plurality of weirs comprise a flat bottom configured to collect the suspended solids from the flow of water.

2. The modular weir of claim 1 , wherein each of the plurality of weirs is thermoformed.

3. The modular weir of claim 1 , wherein each of the plurality of weirs comprises one or more body connections configured to connect a first wall and a second wall of the weir at a top of the weir.

4. The modular weir of claim 1 , wherein each of the plurality of weirs comprises a weir connection at a first end and a weir connection at a second end of the weir configured to connect the weir to another of the plurality of weirs.

5. The modular weir of claim 1 , wherein a length of the plurality of weirs is a same length as a length of a stormwater management crate unit within which the modular weir is positioned.

6. The modular weir of claim 1 , wherein each of the plurality of weirs is configured to fit between the plurality of columns in the stormwater management crate.

7. The modular weir of claim 6 , wherein each of the plurality of weirs is a blow molded tube, a twin sheet thermoformed tube, or an extruded tube.

8. A modular weir configured to isolate suspended solids from a flow of water in a stormwater management crate, the modular weir comprising:

a plurality of weirs connected together, the plurality of weirs being configured to isolate the flow of water from the stormwater management crate, wherein each of the plurality of weirs comprises:

a tray with a bottom; and

a first wall and a second wall, wherein the first wall and the second wall extend at an angle from the bottom of the tray to a top of the plurality of columns in the stormwater management crate;

a plurality of column grooves along the plurality of weirs configured to extend around a plurality of columns in the stormwater management crate;

an inlet located at a first end of the plurality of weirs configured to receive the flow of water within the stormwater management crate; and

a cap located at a second end of the plurality of weirs configured to contain the flow of water within the modular weir.

9. The modular weir of claim 8 , wherein the first wall and the second wall comprise a plurality of column grooves configured to wrap around the plurality of columns in the stormwater management crate.

10. A modular weir configured to isolate suspended solids from a flow of water in a stormwater management crate, the modular weir comprising:

a plurality of weirs connected together, the plurality of weirs being configured to isolate the flow of water from the stormwater management crate, wherein each of the plurality of weirs comprise:

a first tray having a first wall, a second wall, and a central surface;

a second tray having a first wall, a second wall, and a central surface;

a first connection surface; and

a second connection surface,

wherein the first wall and the second wall of the first tray extend at an angle from the central surface of the first tray;

the first wall and the second wall of the second tray extend at an angle from the central surface of the second tray;

the first connection surface being located at an end of the first wall of the first tray and the second wall of the second tray; and

the second connection surface being located at an end of the second wall of the first tray and the first wall of the second tray;

a plurality of column grooves along the plurality of weirs configured to extend around a plurality of columns in the stormwater management crate;

an inlet located at a first end of the plurality of weirs configured to receive the flow of water within the stormwater management crate; and

a cap located at a second end of the plurality of weirs configured to contain the flow of water within the modular weir.

11. The modular weir of claim 10 , wherein the first tray and the second tray comprise a plurality of column grooves configured to wrap around the plurality of columns in the stormwater management crate.

12. A modular weir configured to isolate suspended solids from a flow of water in a stormwater management box, the modular weir comprising:

a plurality of weirs configured to isolate the flow of water from the stormwater management box;

a column extension extending at a right angle from each of the plurality of weirs, wherein the column extension is configured to extend between a plurality of columns in the stormwater management box;

an inlet located at a first end of the plurality of weirs configured to receive the flow of water within the stormwater management box; and

a cap located at a second end of the plurality of weirs configured to contain the flow of water within the modular weir;

wherein each of the plurality of weirs comprises a flat bottom configured to collect the suspended solids from the flow of water.

13. The modular weir of claim 12 , wherein each of the plurality of weirs is thermoformed.

14. The modular weir of claim 12 , wherein each of the plurality of weirs further comprises one or more body connections configured to connect a first wall and a second wall of each of the plurality of weirs at a top of each of the plurality of weirs.

15. The modular weir of claim 12 , wherein each of the plurality of weirs further comprises a weir connection at a first end and a weir connection at a second end of the weir configured to connect to another weir of the plurality of weirs.

16. A flat sheet weir configured to isolate suspended solids from a flow of water in a stormwater management box, the flat sheet weir comprising:

an inlet configured to receive the flow of water within the stormwater management box;

a top column panel and a bottom column panel configured to cover a top plate and a base plate of the stormwater management box; and

a first side panel and a second side panel configured to extend between the top column panel and the bottom column panel outside a plurality of columns in the stormwater management box.

17. The flat sheet weir of claim 16 , wherein the top column panel and the bottom column panel further comprise a plurality of openings configured to fit around the plurality of columns in the stormwater management box.

18. The flat sheet weir of claim 16 , wherein the first side panel and the second side panel extend between the top plate and the bottom plate within the plurality of columns in the stormwater management box.
