A stormwater control system including conveyance, filtration and discharge systems. The conveyance system includes a set of conduits and connections providing a flow path through a compacted soil embankment from an upper inlet to a lower discharge area of an underlying soil infiltration zone. The control system has configurations for transferring stormwater from pervious and impervious surfaces to the soil infiltration zone. The control system optionally includes a media filter device that may be installed within the conveyance system to intercept sediment and other contaminants prior to discharge within the underlying soil infiltration zone.
