Drainage Outfalls

All drainage pipes discharging into an open water course should be fitted with a suitable headwall to protect and locate the outfall pipe and minimize erosion at the discharge point. J.K.H. manufacture a range of headwalls to suit all pipe sizes up to 1800mm outside diameter. Generally pre-cast headwalls can be installed at a fraction of the cost of in-situ structures and have the advantage that during major maintenance work they can be removed and refitted.
