What are Silt Traps?

Silt traps for drainage are basin like devices placed upstream from a soakaway crate or sewer system. The purpose of a silt trap is to keep substances with the potential to cause blockages, such as silt, soil, sediment, or pieces of metal from entering your water drainage system. They do this by temporarily collecting water in the trap, allowing the silt to settle at the bottom of the basin. After this the trap releases the water minus the silt and allows it to flow through into the drainage system.

How Do Silt Traps for Drainage Work?

While there are many different types of silt traps, they all operate based on the same principle. Before entering the drainage system, the water is directed into the catch pit drainage system. As the trap fills with water, the silt settles at the bottom, below the invert of the pipe. When the water reaches the level of the pipe, it leaves the silt trap, and the silt behind, while it continues to the drainage system.

You can make silt traps using bricks or precast concrete. However, these can be unreliable. We would always recommend a prefabricated silt trap. Our silt traps are designed with the exact purpose in mind and are available with more advanced filtration systems that can catch even finer silt particles.
