Abstract: A vacuum truck solids handling apparatus includes a truck having an internal combustion engine and a truck frame. A vacuum source, a solids collection container and a separator assembly are all mounted on the truck frame. The separator assembly is adapted to separate solids from a fluid stream drawn under vacuum by the vacuum source. The separator assembly has a pivotally mounted discharge, which pivots between a closed discharge position and an open discharge position. In the closed discharge position, the discharge discharges solids into the solids collection container. In the open discharge position, the discharge discharges solids externally.
