Simple Installation (estimated time 5 min):​

  1. Connect the 4' tether (included) to the storm drain grate by creating a simple loop around one of the horizontal grate slats using the "D-loop" connectors. 

  2. Attach the ClearTec™ Passive Skimmer to the 4' tether by connecting the clip end on the Passive Skimmer to the smaller "D-loop" connector on the tether.

  3. Drop the ClearTec™ Passive Skimmer into the storm drain. It will float on any water that may be in the storm drain or will hang via the tether until water enters the storm drain during rain. The Passive Skimmer will always remain buoyant until it is replaced even when fully saturated with Oil, Gas, Grease, TSS, and Phosphates.

  4. Replace the storm grate over the storm drain opening

Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.
