Alternatively, the base of the branch channel is allowed to sit on the lip of the main channel, although the branch channel itself is cut to such an angle that it does not project into/over the main channel itself. This is important as, if a section runs too far without a manhole, it can make it impossible to carry out essential drain surveys, drain repairs and drain jetting. Sometimes manholes are created with space for square slabs above them which allow the manhole to blend into its surroundings. You can create your listing free at DIYnot Local.
