Ultra-Drain Guards®

Ultimate Model

Ultra-Drain Guard. The original catch basin insert.
The ultimate in catch basin inserts removes dirt, sediment, hydrocarbons, and utilizes an effective antimicrobial coating

Out of sight shouldn't mean out of mind. At least not when it comes to stormwater management. While many of UltraTech's products are designed to prevent pollutants from entering the system through the drain, the catch basin (the part that's "out of sight") shouldn't be ignored.
Strips of antimicrobial material, attached to the bottom of this catch basin insert, mix with any standing water present. These coated "tentacles" help resolve issues of bacteria and algae-laden water often found in catch basins.
Key Features:  
  • Same hydrocarbon and sediment removal capabilities as the Ultra-Drain Guard, Oil & Sediment Plus Model but with additional antimicrobial properties.
  • 1.5” x 20” strips of Ultra-X-Tex AM (Antimicrobial) hang from the bottom of the Drain Guard and become immersed in standing catch basin water, allowing contact with destructive bacteria.
  • Antimicrobial coated Ultra-X-Tex “tentacles” help address stormwater-related issues with single-cell organisms (bacteria, fungi, yeast, and algae) that are found in stagnant stormwater and catch basins.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.

Frequently Asked Questions

What's the difference between this and your standard Ultra-Drain Guard?
Other than the additional strips of Ultra-X-Tex AM material sewn to the bottom, there is NO difference.  We start with Oil & Sediment Plus Drain Guard(Part# 9219) and simply add the X-Tex AM strips.  Everything from a construction and performance standpoint is the same.


How much water can the Drain Guard handle?
When new, the Drain Guard has a flow rate of 90 gpm/ft2. However, the unit has been designed with overflow ports.  These allow the Drain Guard a flow rate of 770 gpm which will prevent any flooding or ponding during extreme rain events.  Any water that goes through the overflow is essentially untreated.


How long will a Drain Guard last?
It is difficult to arrive at a definitive answer for this as there are several factors that will determine how long an Ultra-Drain Guard, Ultimate Model will last after it has been installed.  The amount of rainfall and the amount and type of pollutants that the unit will be exposed to, among other things will determine the Drain Guard's life expectancy.  For this reason, we recommend inspecting the unit after each significant rain event to better understand how much each Drain Guard will capture.  We have had test units in Seattle as well as Florida that were still working effectively after more than a year after installation.


Can the Ultra-Drain Guard be reused?
Yes, under most circumstances.  If the Drain Guard is filled with sand, silt, and sediment, it can be removed from the drain, emptied out and replaced.  Trash and debris can also be removed.  The exception is if the Drain Guard is saturated with oil, gas or other hydrocarbons.  Because these pollutants can be flushed out of the Drain Guard by a major rain event, it is recommended that the units be replaced instead of reused.


Are Drain Guards difficult to install?
Usually, the most difficult part of installing an Ultra-Drain Guard is the handling of the catch basin's grating.  Depending on the area, these grates can be large and heavy and therefore a challenge to lift/move.  For that reason, a second set of hands is recommended.  The rest of the installation is quick and easy.  


What size drains will this Drain Guard fit?
The Ultra-Drain Guard, Ultimate Model is designed to be installed in drains up to 30" x 40".


What other products could be used instead of the Drain Guard, Ultimate Model? 
With the exception of the antimicrobial properties, you could achieve similar results by using one of our other Drain Guards.    You can also check out thePath to the Perfect Productto see what other products might be a good option.
