The ParkUSA® Grate Inlet Filter™ is a stormwater best management practice (BMP) device designed to fit within common basin structures to provide an economical best management practice solution. In this way, stormwater runoff treatment provides protection from pollutants entering aquifers, public waterways, streams, rivers, and lakes. Vehicles traveling over streets, driveways, and parking lots leave hydrocarbons from vehicle lubricant leaks, metals produced by brake pad wear, and tire residue. These pollutants are picked up by stormwater runoff during the storm’s “first flush” event when pollutant concentration is highest. As rainwater accumulates on pavement, the stormwater will flow to the lowest point, where catchment structures like catch basins and curb inlets are typically installed. These basins present an opportunity to pre-filter the stormwater prior to discharging into the storm sewer. The grate inlet filter provides the best solution to pre-filtration requirements on these types of events.​

Dolor Sit Amet

  • Pre-engineered to fit any inlet basin or curb inlet
  • Stainless steel construction
  • Overflow protection
  • Easy installation and maintenance
  • Designed to fit in common catch basins
  • Light-weight removeable debris collection basket
  • Prevents loss of valuables
  • High flow bypass feature
  • Engineered as a stormwater pretreatment device

As stormwater passes through the grating, debris larger than the grate openings are prevented from entering the storm sewer. Flow goes through a skimmer tray and encounters the hydrocarbon absorption boom. The stormwater and collected solids flow down to the lower filter unit, where separation and capture of the solids occurs. The treated water goes into the catch basin and flows out through the basin’s discharge piping. Finally, the collected debris dries after each storm event and can be removed for proper disposal.​
