Abstract
A debris-filtering downspout and other water runoff conduits and receptacles are disclosed, and include a screen mounted within a conduit, a culvert, a storm water conveyance or secured to a water collection basin. The screen provides high water throughput and is self-cleaning while effectively filtering debris contained in an incoming water stream. Optionally, media pads may be included to further scrub the water before it exits the downspout assembly.
