The ‘Sewers for Adoption’ & ‘Sewers for Scotland’ Guidelines call for an Outfall Safety Grille to be fitted to any Headwall with a pipe opening of 350mm or greater. The Guidelines specify that the grille must be a minimum of 270mm wider that the outside diameter (OD) of the pipe, have bars at 100mm spacing, be hinged and have a padlock facility. Standard Gratings are hot dip galvanised to BS EN 1461 after fabrication but are all available in Stainless Steel if required.
Althon provide five types of an Outfall Safety Grille, Type 2 is hinged on both sides has a padlock facility at the top and bottom and bars at 100mm spacing. This type is particularly useful where space on the apron is restricted either due to length or if there is a requirement for stepped baffle blocks etc.
