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

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.
