Screening apparatus (101,901) for use at an overflow weir (301, 902) in a
sewerage system. The apparatus comprises a continuous moving screen band
(201,902) and a band cleaning mechanism (608). A first portion (801) of
the screen band is configured to move along the weir towards one of its
ends, and a second portion (803) of the screen band is configured to move
along the weir towards its opposite end. A steeper portion (805) of the
screen band extends to an elevated position (806) above the first and
second portions, and the band cleaning mechanism is arranged to remove
solid matter from the screen at said elevated position.
