Silt Traps And Catchpits For Infiltration

Silt traps serve a key purpose in the perfect infiltration drainage application. Also referred to as a pre-filter, a silt trap is placed up-stream of the void (a soakaway crate wrapped in geotextile membrane) so that stormwater passes through the trap before it is able to enter the soakaway.

As stormwater passes through the trap, any silt, sediment, or litter in the water will be caught and prevented from entering the soakaway. This ensures high water quality, sustainability, and maximum water storage in the crate part of the infiltration system.

Our silt sentinel silt traps are manufactured by Turtle Enviro, who’s sentinel range of products are a leading brand in the construction industry. Each trap is supplied with a lid and a silt bucket, also known as a catch basin, that sits within the trap and can be removed easily removed for maintenance purposes.

This range features a wide variety of chamber depths and lids to support various tonne loadings and allow for installation in a variety of urban environments.

What is infiltration drainage?

An infiltration drainage application is used for holding stormwater underground and allowing it to disperse, or infiltrate into the surrounding soil at a controlled rate with the highest quality of water possible. Stormwater usually enters the system from the guttering of a property, once it flows through the downpipe and into the underground drainage pipes, it can enter an infiltration system.

An infiltration system will most often start with a pre-filter that removes any silt or fine sediment in the water, before allowing it to flow into the main part of the system, that being a soakaway crate wrapped in a membrane. The crate is where the water is temporarily stored and the membrane surrounding it ensures not only that the surrounding soil does not make its way into the system but also that the stormwater leaves the system at a controlled rate.
