5. At its downstream end, the FP6 area willdischarge into an existing ditch which leads tothe outlet flat-V weir. A flapped 250mmdiameter orifice at the outlet of the ditchbeneath the flat-V weir will be provided forland drainage purposes. For details of the FP6outfall see drawing no. HQ22135/CLR/EA/15.
