RSFA11A Rectangular Precast Headwalls are Sewers for Adoption compliant precast concrete headwalls for outfalls discharging into ponds, swales, ditches beaches and rivers. RSFA precast headwalls come with the option of two thicknesses of toe, 300mm and 500mm, each of which is available in three depths. 

Althon RSFA11A rectangular precast headwalls have sloped wingwalls and are suitable for use with plastic or clay pipework up to 225mm.

Althon RSFA11A precast headwall units can be pre-fitted with a range of accessories such as flap valves, penstocks, Kee Klamp® handrails and a selection of gratings depending on the application.

Our RSFA11A precast headwalls are manufactured in accordance with Severn Trent Water Standard detail STD6002

All RSFA Headwalls are cast with the opening in the back wall to suit the size and type of pipe being used at the invert level required.

The RSFA11A headwall weighs 1136kg
