Systems, apparatus, and methods for maintenance of stormwater management systems

A method for forming a stormwater chamber, flared end ramp, and inlet cap system for managing flow of material into a stormwater chamber, the method comprising:

• providing a flared end ramp having a first end and a second end, and a ramp surface configured to incline from the first end to the second end, the ramp surface including at least one drainage groove extending between the first end and the second end;
• forming a support foot attached to the ramp;
• providing a stormwater chamber inlet end cap;
• connecting the flared end ramp to the chamber inlet end cap;
• and
• attaching the ramp and end cap to the stormwater chamber.

A method for containing and filtering stormwater runoff, the method comprising:

• providing an inlet apparatus configured to receive runoff from a surface-level drain, the inlet apparatus including at least one of an elevated bypass manifold or an overflow weir;
• providing a first stormwater chamber configured for placement underground, the first stormwater chamber being configured to store the runoff and extending between a first end cap with at least one opening and a second end cap;
• providing at least one additional stormwater chamber arranged side-by-side with the first stormwater chamber to form an array of stormwater chambers, wherein the array of stormwater chambers is fluidly connected via the inlet apparatus and is configured to receive the runoff from the inlet apparatus wherein each additional stormwater chamber is configured to store stormwater between a first end cap with at least one opening and a second end cap;
• and
• providing a flared end ramp configured for placement within at least one of the stormwater chambers, the flared end ramp including:
• an inlet end configured for connection with an inlet pipe, the inlet pipe extending through the at least one opening in the first end cap of the at least one stormwater chamber and connecting to the inlet apparatus;
• an outlet end configured for placement within the at least one stormwater chamber;
• 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 at least one stormwater chamber, 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.
