Where a Headwall is part of a Section 104 Agreement and the Sewers are to be adopted once completed by the local Water Company then the materials used and installation must comply with the ‘Sewers for Adoption’ guidelines. Althon SFA Precast Concrete Headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses.
We cast the opening in the back wall of our headwalls to suit the pipe diameter and material of the pipe being used. We can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of our headwalls. We can also cast pipe openings into the wing walls of our headwalls.
All Althon SFA Headwalls are available with either 300 or 500mm thick toe extensions. If you cannot find the drawing or information you are looking for please contact us.

Althon Headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open water courses.
All drainage pipes discharging into open watercourses, such as swales, ditches, ponds and rivers, should be fitted with an appropriate Althon headwall.
