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

A stormwater management system for containing and filtering runoff, the stormwater management system comprising:

• 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;
• 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;
• an inlet pipe configured to fluidly connect with the inlet apparatus and to extend through the at least one opening in the first end cap into the first stormwater chamber;
• a flared end ramp configured for placement within the first stormwater chamber, the flared end ramp including:
• an inlet end configured to receive the runoff from the inlet pipe,
• an outlet end configured to distribute the runoff across a width of the first stormwater chamber, and
• an inclined surface extending continuously between the inlet end and the outlet end of the flared end ramp;
• a filtration fabric configured to be situated beneath at least a portion of the open bottom of the first stormwater chamber, wherein the filtration fabric is configured to capture sediment from the runoff in the first stormwater chamber while the runoff flows out of the first stormwater chamber;
• a non-woven geotextile fabric configured to cover the first end cap and at least a portion of an exterior surface of the first stormwater chamber;
• and
• 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 and to disperse filtered runoff into at least one of the earth or an underground drainage structure.
