In the stormwater management market, precast sand traps are the answer to unique filtering requirements. Precast sand traps, also known as sand filters, capture sediments from runoff water, solve particle separation problems, and lower phosphate levels. 

​

These vaults contain two chambers, one for filtering large debris and particulates and another that contains the sand to filter contaminants from the water itself, including emulsified liquids. The sand filter is typically situated between a collection structure and water piping. Each filter can be sized to match your application, thereby making processing and maintaining more efficient. Sand filters are available in a variety of sizes and feature a high-flow bypass to comply with underground structure requirements.
