Catchpits / Silt Traps & Fabrications

We design a range of catchpits/ silt traps to separate silt and other particles. This improves the quality of water before it is reintroduced back into the drainage system.

As each individual SuDS system is different, they are individually fabricated to take into account water flow rates and ground conditions that differ from site to site. Our catchpits are widely and successfully being used for applications including railway and highway drainage systems.
