摘要

A waste water treatment basin has a drainage gutter cleaning assembly in which the cleaning-brush vertical swivel axis and the vertical axis of the upright frame are especially coaxial. The brush-holder is fixed to a slide on the vertical frame, on which it may be raised to a height at which the brush unit can be reached from the rotating gantry.
