Aqua-Guardian™ catch basin insert by AquaShield™ Inc., provides a highly effective means for the removal of sediment, floating debris and free-oil normally present in the "first flush" or the stormwater that initially runs off an area that is more polluted than the stormwater that runs off later. These inserts are perfect for retro-fit applications. For more information about Aqua-Guardian™ visit www.aquashieldinc.com or give us a call at ETG. |
