A method of collecting and transferring settling solids that are being settl ed from raw surface water or wastewater includes collecting settling solids and applying first (F1) and second (F2) upward flows to the settling solids. The solids are collected in a chamber (60) having a bottom surface (61a) and a surrounding side surface (61b). The first upward flow (F1) is applied to the solids from a point adjacent the bottom surface (61a). The second upward flo w (F2) is a suction flow applied at a point above the first upward flow (F1). The first (F1) and second (F2) flows urge the settling grit upward and out o f the chamber (60) through a passageway (76).
