Abstract: A rainwater ducting system mounted adjacent the eaves of a building is comprised of a horizontally disposed open gutter containing horizontally directed auger means and a communicating downspout containing vertically directed auger means. The auger means are designed to occlude less than 50% of the cross sectional area of the trough and downspout, and are separately activated by waterproof motors remotely controlled and adapted to provide variable forward and reverse speeds. In operation, the auger means advance solid debris toward and downward through said downspout.
