Above Grate Filter

GrateGator is an above-the-grate stormwater filter that removes sediment and debris from stormwater as it enters the catch basin. The device is a durable, high-flow filter. Clean, maintain and reuse it for the duration of your project. With built-in overflow protection, it provides an efficient solution for filtering contaminants while allowing bypass during extreme wet weather events.

Ferguson Waterworks Offers Multiple GrateGator Products:

  • HD Unit: an over-the-grate system designed to stay secure without the hassle of lifting the grate
  • Grategator Skirt: slides over the grate and has a flip top for maintenance
  • Grategator Magnets: attaches to the grate with high-strength magnets
  • Grategator Magnets and Overflow: attaches to the grate with high-strength magnets but also it has a collapsible overflow which provides vertical containment that will collapse under vehicle traffic

Key Features:

  • Lightweight
  • Easy to use and reuse
  • No stone or sand is required
  • Optional overflows
  • Optional curb inlet filters

Additional Construction-Phase Drop-Inlet Devices:

  • EconoSack: a below-the-grate filter device that protects stormwater systems from trash, sediment, and debris.
  • Siltsack: protects catch basins from construction runoff.
  • SediBag: slides over the grate to stop debris from entering the catch basin
