These gullies vary in internal size and outlet diameter. The increasing size of the gully increases the amount of silt that they can retain and/or extends the maintenance interval. The drainable area is usually controlled by the ability of water to get through the surface grating.


SuperSleve gullies and traps are Kitemarked to the requirements of BS EN 295-1 and are supported by a CE mark and DoP.
