9 . The apparatus of claim 8 , further comprising a flared end ramp comprising: an inlet end configured to connect to the pipe; an outlet end configured for placement within the stormwater chamber; a protrusion on an outside of the inlet end configured to abut the flared end ramp with the end cap; and an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber, wherein 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.
10 . The apparatus of claim 9 , further comprising an indent on an upper side of the inlet end configured to prevent the pipe from sliding towards the outlet end.
11 . The apparatus of claim 10 , wherein the indent protrudes upward from the upper side of the inlet end to a distance that is level with an inside diameter of the pipe.
12 . The apparatus of claim 9 , wherein the inclined surface includes at least one drainage groove extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp, the drainage groove angled laterally outward from the inlet end toward the outlet end.
13 . The apparatus of claim 8 , wherein the end cap further comprises: an arch surface touching a top of the sleeve; and two concave flared surfaces adjacent to a lower half of the bore connecting the sleeve to the arch surface.
14 . The apparatus of claim 13 , wherein the arch surface includes one or more notches configured to connect to a protrusion in the stormwater chamber.
15 . The apparatus of claim 13 , wherein the arch surface is configured to interface with the scalloped edge portion of the stormwater chamber.
16 . The apparatus of claim 8 , wherein the bore is oval shaped with a dimension along a horizontal axis longer than a dimension along a vertical axis.

Description

CROSS REFERENCE TO RELATED APPLICATION This application is based on and claims benefit of priority of U.S. Provisional Patent Application No. 63/309,054, filed on Feb. 11, 2022. The content of the foregoing application is incorporated herein by reference in its entirety. TECHNICAL FIELD This disclosure relates generally to systems, apparatus, and methods for fluid run-off management systems. In particular, this disclosure relates to enhanced components of stormwater management systems and components thereof. BACKGROUND Fluid run-off systems include systems designed to process rainwater or other fluid run-off and particularly stormwater. Related stormwater management systems known in the art include chamber systems designed primarily for use under parking lots, roadways, and heavy earth loads. Stormwater chambers may be thermoplastic, injection molded, and formed of polypropylene, polyethylene, or a combination thereof. Such a chamber has an arched cross-section, and is formed to have a long, narrow configuration with an advantageously compact footprint that optimizes use of space. The arch-shaped chamber defines an open bottom. The chamber may be installed and placed on crushed stone or other porous medium, which constitutes a floor of the chamber underlying the arch. The chamber may be formed to include corrugations, which may be advantageously shaped and configured to accommodate efficient stormwater or fluid run-off management and debris collection. One or more chambers include an inlet configured to connect to a stormwater collection system, which may include one or more drain basins that receive fluid run-off from a parking lot, roof, or street. The one or more chambers are designed to distribute collected stormwater into the ground. During a storm, stormwater or rainwater run-off enters the chamber from the one or more drain basins, and in some system configurations, may exit the chamber by flowing through a conduit connecting the chamber to another system component, such as a basin or another chamber. By way of example, a chamber-type stormwater management system may include an array of chambers buried in crushed stone. The chambers may be connected in parallel or in series. Stormwater carries debris and solid contaminants that can pass into and through basins, traps, and filters of conventional stormwater management systems. Stormwater may include suspended solids, including dirt, sand, organic debris such as leaves, paper, and plastic. Stormwater management system chambers may be configured to receive stormwater and allow debris to settle to a bottom of the chamber before the stormwater is released into the ground. Related stormwater management systems known in the art may include a subsystem by which stormwater first flow into a primary chamber situated among a row of chambers dedicated to capturing a large amount of debris. The primary chamber may be encased in a geotextile mesh or filter fabric forming a fine mesh made of any suitable now known or later developed material. Other chambers in the system, including the other chambers in the row of chambers, may also be encased in a geotextile mesh or filter fabric forming a fine mesh made of any suitable material. The filter fabric encases the chamber, interposing the chamber and the crushed stone floor. Debris and solid contaminants have been found to locally mask and block exit points in the filter fabric, impeding outflow of fluid or water from the chamber into the ground. Accordingly, maintenance is required to ensure optimal functionality of chambers, whether they are primary chambers, other chambers among a row of chambers, chambers in a system without a primary chamber, or chambers in systems with or without other means of debris and solid contaminant collection. Debris is typically manually removed from an interior of a chamber using a device configured to jet water into and through an interior of the chamber to force debris and fluid out of the chamber for collection by vacuum. In particular, jetvac systems use a high-pressure water nozzle to propel water through a length of a chamber to suspend and remove sediment. The high-pressure spray from the nozzle causes the sediment to exit the chamber into, for example, a connected basin wherein the collected sediment is collected by vacuuming. The jetvac system and similar cleaning devices can snag, tear, or otherwise disrupt the filter fabric material, damaging an efficacy and functionality of the chamber. Accordingly, systems have been designed to protect a floor of the chamber. For example, some systems include a multi-layer mat as an additional component used to protect the filter fabric material during a cleaning and maintenance process. Related chambers known in the art and used in chamber-type stormwater management systems include end caps that attach to the chambers. The ends of the chambers are capped to prevent entry of gravel, earth, or other particulates that would disrupt the filter
