Our SFA28 outlet range of precast concrete headwalls for adoption are designed to comply with Sewerage Sector Guidance for pipework discharging into open watercourses for pipework up to 1500mm. We cast the opening in the back wall of our precast 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 precast concrete headwalls. We can also cast pipe openings into the wing walls of our headwalls. We can factory fit all our precast SFA headwalls with Kee Klamp® handrails, Sewers for Adoption specification gratings, flap valves, penstocks and other flow control devices.
Althon Sewers for Adoption precast headwalls are available with either 300 or 500mm thick toe extensions.
