Wherever water is to be fed from an open watercourse into a pipe, a suitable silt trap inlet should be provided. The sloped gratings provided minimize the risk of blocking from floating material, and the silt chamber will collect the worst of the heavy objects and silt. It is, of course, essential that all sites where such units are required, should be regularly inspected and the accumulating rubbish and silt be removed to avoid 'over-topping' and flooding. J.K.H. manufacture a range of silt trap inlets to cater from 150mm pipe up to 1400mm.
