Drain Guard for Trash and Debris

The Ultratech 9227 model is a new personal protective equipment item designed to filter stormwater drains. It uses a black non-woven polypropylene geotextile to capture trash and debris before they enter the drainage system. This unit suits maintenance crews and site managers who need to protect drain inlets on active job sites.

Flow Capacity and Opening Constraints

The guard fits almost any drain with a 10 in diameter opening and handles a flow capacity of 500 gpm. Its flat dimensions of 48 in by 36 in cover the grate while the 18 in height provides the necessary settling depth. Flows exceeding the rated capacity or debris loads heavier than the material tensile strength will bypass or overwhelm the filter.

Oil Retention and Service Limits

The geotextile material retains up to 7.4 gal of oil and hydrocarbons alongside solid waste. It comfortably handles routine sediment, litter and hydrocarbon sheen from parking lots or wash-down areas. The guard runs out of capacity when the oil saturation reaches the 7.4 gal limit or when accumulated solids blind the fabric and restrict the 500 gpm flow rate.
