Systems, apparatus, and methods for isolating flow in a stormwater management crate array

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.

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.

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.
