ABSTRACT:
A beach for the scum trough of a sewage settling tank or the like is biased to an upright position by a weighted member or the like so as to prevent the flow of liquid over the beach and into the scum trough. The construction of the beach allows it to be rotated against this bias to a second position below the level of liquid in the settling tank, so as to permit scum and other floating materials accumulated adjacent the beach to flow over the beach and into the scum trough.
