A stormwater detention system includes a containment row for removing and collecting solids from stormwater. The containment row may be surrounded by a water-impermeable membrane, and designed to receive incoming water before other rows of the detention system. The containment row collects solids from the stormwater before the water is redirected into one or more additional rows, which are water permeable and buried in water permeable media. Filter structure may be associated with a flow system that delivers water from the containment row to the additional rows.
