An underground stormwater management system includes a first-flush chamber that receives the first flush. The chamber removably holds filter cartridges that close the chamber and filter the first flush as the first flush drains out of the chamber and into an underlying porous substrate. When the filter cartridges are used up, they can be replaced with new filter cartridges.
