A sewer basket and its support are to be positioned at any selected level within a vertical sewer pipe having an interior surface and an opening, of reduced size or not, at street level. The basket support is secured to the interior surface of the sewer pipe to receive the basket that includes a plurality of filter units adjacently and releasably resting on the basket support. Each filter unit is so sized as to get through the sewer opening while being in a substantially horizontal orientation. Each filter unit includes a frame, a filter screen secured to and closing the frame, and a handle device accessible from the pipe opening to properly position, place and retrieve the unit on and from the basket support respectively. Preferably, an intermediate support having a generally flat lattice shape releasably rests on the basket support to itself support the filter units.
