HYDRAULIC PERFORMANCE OF CONFLICT JUNCTION BOXES

This report documents an experimental investigation of the hydraulic performance of typical conflict junctions, installed when utility conduits intersect a stormwater drainage line. The conflict pipe disrupts the jet flow across the box creating additional losses and resulting in decreased capacity. As would be expected, the loss depends directly on the size of the conflict pipe, but also the loss increases when the conflict pipe is large in relation to box size. The results of this investigation have been summarized as appropriate design information. Recommendations for application of this information to achieve efficient system performance are presented.
