Abstract
An input channel (and method of making an input channel) for the flow of waste water into a grit removal unit. The input channel has a depth D extending from the bottom to the top of the channel. One side wall of the channel is configured to vary the channel width over the depth of the channel, whereby (a) the width at the bottom of the channel is W, (b) the width at the top of the channel is W, and (c) the width at channel depth 'd' above the bottom of the channel is W, wherein (i) 0≦d≦D, (ii) W<W, and (iii) Wis greater than or equal to the channel widths at substantially every channel depth less than 'd'. The channel profile may be integral to the channel, or defined by a separately added component, and selectively be stepped, tapered and/or curved.
