Ultra-Drain Guard Pellet Trap Model

When new, the Ultra-Drain Guard has a flow rate of 60 L/m2/s. However, the unit has been designed with overflow ports.  These allow the Ultra-Drain Guard a flow rate of 909 litres per minute which will prevent any flooding or ponding during extreme rain events.  Any water that goes through the overflow is essentially untreated.

The material called needle-punched geotextile can soak up synthetic oils. However, the Ultra-Filter-Tex material cannot soak up synthetics, it’s designed specifically for hydrocarbon absorption only.

The lifespan of an Ultra-Drain Guard after installation depends on several factors, including rainfall intensity and pollutant volume. Inspecting the unit after each significant rain event is recommended to evaluate its performance.

If the Ultra-Drain Guard is filled with sand, silt, and sediment or has collected debris, it can be removed, emptied, and replaced. However, if it has been saturated with oil, fuel, or other hydrocarbons, it is recommended to dispose of the unit and replace it with a new one. This is because these pollutants can be flushed out during heavy rain events, contaminating the surrounding environment. Replacing the unit is a safer option to avoid potential environmental hazards.

Usually, the most difficult part of installing an Ultra-Drain Guard is the handling of the catch basin’s grating.  Depending on the area, these grates can be large and heavy and therefore a challenge to lift/move.  For that reason, a second set of hands is recommended.  The rest of the installation is quick and easy.

The straps on an Ultra-Drain Guard are used to remove it from the catch basin. Before lifting the grate, the lifting straps sewn into the top of the unit should be fished out and brought up through the drain’s grating. Then, a piece of rebar, steel rod, or a shovel or broom handle can be inserted through each set of straps. This way, when the grating is lifted, the Ultra-Drain Guard will be lifted with it instead of dropping into the catch basin.
