Advanced Drainage Systems, Inc.

Stormwater management systems, methods, and apparatuses for containing and filtering runoff are provided. Disclosed embodiments may include a top plate including a first plurality of side panel attachments and a bottom plate including a second plurality of side panel attachments. Embodiments may include a plurality of support column assemblies between the top plate and the bottom plate. Each support column assembly of the plurality of support column assemblies may include an upper portion and a lower portion and the upper portion and lower portion may be configured to connect at a mating connection. Embodiments may also include one or more side panels. Each of the one or more side panels may include one or more column bearing components. The one or more column bearing components may be configured to contact at least one support column assembly of the plurality of support column assemblies at one or more contact areas. The one or more contact areas may be located above or below the mating connection. Stormwater management crates may be arranged into an array and include side panels of variable heights. The array of stormwater management crates may be further wrapped in sediment impervious material and serve to restrict stormwater flow as part of a stormwater management system.

A coupling configured to connect a first pipe to a plurality of pipes comprising a first end and a second end, wherein the second end is tapered and comprises a plurality of lateral ribs and a plurality of longitudinal ribs, wherein each of the plurality of longitudinal ribs comprises a pliable and wedge-like shape, and each of the plurality of longitudinal ribs tapers toward the second end.

A flared end ramp for managing and distributing fluid runoff. The flared end ramp may have an inlet end configured to connect to a pipe, a plurality of protrusions on the upper side of the inlet end, and an outlet end. An inclined surface may extend between the inlet end and the outlet end of the flared end ramp, the outlet end of the flared end ramp has a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end. The flared end ramp may include a tab positioned on an edge of the outlet end, the tab extending vertically relative to the outlet end. The flared end ramp may be placed inside a stormwater chamber, and the tab may be positioned outside of the stormwater chamber.

Stormwater management systems, methods, and apparatus for containing and filtering runoff may be provided. In one implementation, a stormwater management crate for managing stormwater runoff may be provided. The stormwater management crate may include a top plate having a first plurality of support column attachments and one or more support column assemblies located below the top plate; the one or more support column assemblies being affixed to the top plate at the support column attachments. The stormwater management crate may further include an intermediate plate may be located below the top plate and above the bottom plate. The intermediate plate may have a third plurality of support column attachments. The intermediate plate may be lightweight and may weigh less than one or both of the top plate and the bottom plate.

A drainage apparatus for fluid runoff comprising one or more grates and a frame having a top portion configured to accommodate the one or more grates. The frame includes a first plurality of plates located within the frame and positioned below the one or more grates. One or more cross members are connected to plates of the first plurality of plates, each of the one or more cross members extends between at least two plates of the first plurality of plates. Each of the one or more grates is secured to a cross member of the one or more cross members.

Stormwater management systems, apparatus, and methods for containing and filtering runoff may be provided. In one implementation, a stormwater chamber may be provided. The stormwater chamber may be configured for use with an endcap for connecting a pipe to the stormwater chamber, and the stormwater chamber may include a first end with a scalloped edge portion. The end cap may include a sleeve with an interior projecting edge, an outward projecting edge, a bore shaped to receive a pipe, a first cutout portion at the upper half of the outward projecting edge of the sleeve, and a second cutout at the bottom half of the interior projecting edge of the sleeve. The stormwater chamber may also include a flared end ramp with an inlet end, an outlet end, and a protrusion on the outside of the inlet end that abuts the flared end ramp with the end cap.
