Nested stormwater chamber end caps.

Abstract

According to disclosed embodiments, a stackable end cap for a manhole containing and discharging stormwater may be provided. The stackable end cap may include an end cap body having a wall with a convex outer surface and a concave inner surface, where the concave inner surface of the wall defines an interior volume of the stackable end cap; a substantially flat foot extending from a lower edge of the end cap body; and a projecting inner flange running along an inner edge of the end cap body.The stackable end cap can be configured to be stacked with at least one additional end cap, such that at least one of the foot or inner flange of the stackable end cap comes into contact with the additional end cap while the body wall of the end cap is separated from a wall of the additional end cap.
