N10D range of precast headwalls are suited for installation where you have steep banks or little depth from back to front for installation

Our N10D range of headwalls are manufactured to the same standards as our Sewers for Adoption headwalls and can be used on Section 104 Agreements where the sewers are to be adopted by the local water company.

N10D headwalls have been designed to suit plastic and clay pipework up to 600mm ID or concrete pipework up to 525mm ID.

N10D precast concrete outfalls are cast to suit the diameter and type of pipe being used and can be provided with fixings cast in at the time of manufacture to accommodate gratings, trash screens, flap valves, penstocks, ladders, Kee Klamp® handrails and flow and depth monitoring equipment.

If you require any assistance or more information please contact us by phone on 01603 488700 or by email sales@althon.co.uk
