Ultra-Basin Guard®

Replace messy hay bales and keep sediment and oil from entering drains and inlets

In many instances, stormwater management products are best kept out of sight.. so long as they are functioning properly.  On a construction site or roadside, however, it can be advantageous to have storm drain protection that also clearly indicates where the drains are located.  

The geotextile material of the Ultra-Basin Guard prevents dirt, sand, sediment, and hydrocarbons from getting into the drain.  The tall sidewalls of the unit help identify storm drains for construction workers, machinery operators and highway maintenance crews.

Key Features:  
  • Prevents silt, sediment, and hydrocarbons from entering storm drains
  • Provides visual indicators to storm drain locations
  • Two standard sizes: Part # 9292 fits up to 24" x 24" grates. Part # 9293 fits up to 4' x 6' grates.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.

The Path to the Perfect Product

Frequently Asked Questions

Why would I use the Ultra-Basin Guard instead of one of your other storm drain products?
The distinction that the Basin Guard has from other products is its tall profile.  Needless to say, a drain protection product that sits 18" above the grate is not suitable for many applications.  But in some situations (usually construction-related), it is advantageous. 

The geotextile material used for the Ultra-Basin Guard is the same as we use in the Drain Guard and other stormwater products so the oil/silt/sediment containment capacities are the same.  But the taller profile provides additional "above the drain" filtering as well as a quick visual identifier of the storm drain's location.


Do I have to take the grate out of the storm drain to install an Ultra-Basin Guard?
It depends.  Part# 9292-O/S requires that you lift the grate, put the Basin Guard over the catch basin and then replace the grate.  However, Part# 9293-O/S does NOT require the removal of the grate and is held in place using gravel, rocks or some other aggregate.


What do I do with the Basin Guard when I'm done with it?
If the unit has only been used to remove dirt, sand, and sediment from the incoming stormwater flow, it can be disposed of like any other trash/waste.  If oil/grease or any other hydrocarbons have been absorbed by the geotextile material, it must be disposed of in accordance with local regulations and requirements.


What other products could be used instead of the Basin Guard? 
As mentioned above, the Basin Guard is fairly unique if a taller profile is a required feature.  However, the Ultra-Filter Socks could be a possible alternative.  The Path to the Perfect Product can help in finding the best solution for your specific application.
