The invention provides structures, methods, and assemblies for bioretention systems, including tree box filters with one or more internal bypass features incorporated into the tree box filter. The invention also provides methods and additional structures that are useful for managing stormwater flow and inhibiting the flow of pollutants, debris, and other contaminants into drainage systems.

Stormwater management system with internal bypass

Structures, methods, and assemblies for stormwater management systems with one or more internal bypass features incorporated into a vault-shaped enclosure are described, along with methods and additional structures that are useful for managing stormwater flow and inhibiting the flow of pollutants, debris, and other contaminants into drainage systems. A first compartment disposed within the vault and comprising a removable bypass pipe, a baffle wall adjacent to the bypass pipe, a screened floatables baffle attached to the baffle wall, and a fluid-conveyance opening disposed along the baffle wall are described. A fluid-conveyance opening is located below the top of a bypass pipe, and a second compartment is in fluid communication with the first compartment through the fluid-conveyance opening. A second compartment is adapted to incorporate a filtration cartridge. An underdrain defined at least in part by the upper and lower floor slabs of the vault is disposed below and in fluid communication with the first compartment through the bypass pipe.

Stormwater filtration system with internal bypass pipe

The invention provides structures, methods, and assemblies for bioretention systems, including tree box filters with substantially permeable panels integrated into a bottom portion of the tree box filter. The invention also provides methods and additional structures that are useful for managing stormwater flow and inhibiting the flow of pollutants, debris, and other contaminants into drainage systems.

Tree box filter with hydromodification panels

A stormwater treatment system, including a treatment container for treating stormwater through a bioretention mechanism. The treatment chamber includes an overflow/bypass system, including a flow distribution tray or flume that includes a distribution compartment or channel, an overflow dam or weir, and an overflow/bypass compartment. The stormwater distribution compartment or channel includes one or more openings for stormwater to be treated to fall onto the filter media located within the treatment container. When high flow rates are obtained that exceed the capacity of the unit, the overflow/bypass stormwater enters the overflow/bypass compartment where it is received by an overflow/bypass outlet pipe to be directed out of the container without such water being treated or further treated by the filter media.
