Sand filters are specialized below ground or perimeter style vaults that are integrated with a stormwater management system. The 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. It is lidded with concrete and contains an access hatch.
Sand filters are incredibly effective at filtering pollutants from runoff. They are versatile and can be used virtually anywhere filtration is needed. Oldcastle Precast manufactures sand filters in a variety of sizes and most take less than a day to install.
We offer a wide variety of electrical vaults and associated products for electrical utilities.
