  • Patent number: 11420880
    Abstract: 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.
