Althon already have a range of RSFA headwalls which have been designed in accordance with Severn Trent Water Standard details STD6002 for pipework up to 600mm & a back wall height of 1100mm.
However, they have had a lot of requests for rectangular headwalls for larger pipe sizes & taller back wall heights. With the increase in height Severn Trent Water require steps for access rather than a ladder.
The accompanying images are a recent bespoke headwall Althon have manufactured to suit a 1200mm PCC pipe, factory fitted with a SFA1 1200 Outfall Safety Grille, Steps and Kee Klamp Handrail.
