What Is A Silt Trap And Why Should I Have One?

Introduction

A silt trap is a basin device that is set upstream of a soakaway crate and its purpose is to prevent any kind of silt, soil, sediment, metals or pesticides from entering your water storage system by containing water in the trap for some time and allowing these unwanted materials to settle to the bottom of the bucket and separate from the water. It essentially works like a filter.

Why do I need a silt trap?

All of the materials mentioned above should not be allowed to flow into a soakaway crate (or any other water storage system) as they will cause damage to it, reduce its sustainability and can sometimes leave you with no other option but to purchase a new one. A silt trap collects these materials in a basket at the bottom of the basin and allows the filtered water to carry on through to your storage system. This basket can of course be easily removed and put back into place when cleaning is required.

Which silt trap will I need?

The type of silt trap you will need depends on the size of your water storage system and the type of environment you are in. For small residential applications, the Silt Sentinel 300 Series is the best choice. It is specifically designed to sit upstream from your water storage system/crate and filter out materials on a domestic scale.

The Silt Sentinel 500 Series is similar to the 300 series but is more appropriate for water storage systems in the medium size range. It would be best for large domestic applications or small to medium sized commercial buildings. Finally the FilterTrap 500 Series is the big one; recommended for large areas of heavy silt and sand like coastal areas or hardstanding landscapes. It will prevent 99% of all sediment from entering your drainage and storage systems.
