General Requirements

Any Stormwater system is only as good as the kerb inlet. There are five essential requirements to this vital structure as follows:

1. Hydraulic Efficiency – This is the most important aspect of a kerb inlet and therefore requires the greatest attention including the need to remain unblocked at all times.
2. Structural Strength – The proximity of this structure to the road requires that it is capable of withstanding any static or dynamic loads to which it may be subjected.
3. Safety – Any deviation of the kerb lines, or the gutter creates a potential hazard for passing traffic or pedestrians.
4. Maintenance – Without suitable access for periodic cleaning, this will soon become clogged and of no use whatsoever.
5. Economies of cost – The Kerb Inlet represents approximately 15% of the value of a stormwater reticulation and should therefore be cost effective.

The Salberg range of Kerb Inlets attends to these needs as appropriate. These are divided into two groups, the first being suitable for use in sub-critical flow conditions and the second, for super-critical flow conditions.

Sub-critical Flow

Type 1: Cover slab for brick chambers
Type 2: Side / end entry chamber
