A prerotation basin for use in a sump pit or wet well includes a basin body having an upstanding exterior wall, an interior concavity for placement of a pump inlet therein, and a fluid entry channel formed in the basin body defined by a discontinuity in the upstanding exterior wall, where the fluid entry channel has a channel floor, the threshold of which is at an elevation that is equal to or lower than the elevation of the bottom surface of the interior concavity. The prerotation basin thereby provides a channel floor that slopes upwardly toward the bottom surface of the interior concavity to provide better solids entrainment in fluid being processed from the sump pit or wet well, and to provide self-flushing of the basin.
