A catch basin filter having apertures and holding a silt barrier material may be securely attached to a drop inlet grate. The catch basin filter has apertures for preventing debris from entering the drop inlet and clogging sewers. A silt barrier material wrapped around the catch basin filter housing provides a study and stable platform for holding the filter in place around the drop inlet such that silt will not be able to enter the sewer and clog it up. The catch basin filter is quickly and easily attached to and removed from the drop inlet by a rod having a hook for extending through the grate bars and then turning the rod to engage the bars on the drop inlet grate to hold the catch basin filter in place. The catch basin filter is durable and reusable and the silt filter material may be easily replaced.
A rooftop drainage device is provided for use in protecting rooftop drainpipes from clogging. An exemplary embodiment of the drainage device includes a filter comprising at least three sides, wherein at least one of the sides includes a plurality of apertures for allowing liquid to pass-through the at least one side into the drainpipe, while filtering debris; and an object receptacle mounted to a top of the filter for removably retaining an object, wherein a weight of the object holds the rooftop drainage device on the rooftop and over the drainpipe without need for mechanical fasteners.
