Storm Drain Protection - How It Works

storm drain filterThe Taurus Hopper fits under the storm drain or catch basin grate, preventing trash and debris from entering waterways and filtering sediment before it enters the storm water system. The hopper (collection area) is larger than traditional comparable products, accommodating large amounts of silt, trash, debris and sand.

This rugged design catches debris while the heavy duty filtration fabric allows water to flow steadily through. Built-in overflow ports allow for an increased flow rate to avoid flooding during heavy rain events. (To increase longevity and performance, we recommend regularly emptying the storm drain filter's hopper.)

Nylon webbing straps are featured for ultimate support and can withstand thousands of pounds of pressure. The (optional) high visibility design makes it easy to quickly identify which storm drains contain the under grate filter. Additionally, Taurus products can prevent mosquitoes from exiting storm drains for flying insect control.

For Maintenance:

  1. Lift the grate using a lifting strap or other approved safety device.
  2. Remove the filter from the grate.
  3. Empty the filter hopper and dispose of the contents.
  4. Reattach the filter to the grate per installation instructions.
  5. Use lifting strap or other approved safety device to replace the grate in the drain opening.
