Althon - headwalls

Althon precast headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses.

All drainage pipes discharging into open watercourses, such as swales, ditches, ponds and rivers, should be fitted with an appropriate Althon headwall.

Althon headwall units can be pre-fitted with a range of accessories such as flap valves, penstocks, Kee Klamp handrails and a selection of gratings dependant on application.
