The Hydro DryScreen® is a next-generation baffle box that captures sediment and screens trash and other solids, storing organic materials dry to prevent nutrient leaching. Improving on the conventional baffle box design with the inclusion of a patented flow diffusing mechanism, the system requires significantly less maintenance than other stormwater treatment systems. Hydro DryScreen® has screening areas that span the entire footprint of the device and are resistant to blinding.
